The World’s Oldest Mummies Are Not in Egypt

by Ermiyas Abiy, age 9

When you think of mummies, you probably picture an Egyptian pharaoh wrapped in strips of cloth. It might surprise you to learn that the world’s oldest mummies are actually thousands of years older and found thousands of miles away.

The Chinchorro mummies of modern-day Chile were preserved more than 7,000 years ago, and are still being found to this day. The Chinchorro people began mummifying and preparing the dead for the afterlife in a harsh environment, with the driest place in the world located in Northern Chile or the Pacific coast of South America.

The Chinchorro inhabited the bays of the harsh Atacama Desert from around 7,000 BC to 1,500 BC. They developed the most unique techniques for mummification around 5,000 BC. [Read More]

When the U.S. and Mexico Went to War

by Gerard Sanchez, age 10

Today, Mexico and the United States of America are neighbors; however, 180 years ago, they were at war.

The two countries fought over the territory between the Rio Grande and the Nueces River. Mexico declared that the border was 100 miles to the east, but the U.S. did not respect the boundary and instead claimed that Texas ended at the Rio Grande.

Texas became a state in 1845. That same year, President James K. Polk sent soldiers to the contested zone to protect Texas. When the American troops reached the Rio Grande, they started fighting with Mexican troops near Palo Alto. Five days later, on May 8, 1846, the U.S. declared war on Mexico. [Read More]

The Puzzle with 42 Quintillion Possibilities

by Dellany Onyango, age 9

There are 42 quintillion ways to move a Rubik’s Cube to solve it! This colorful, brain-teasing puzzle has challenged and fascinated people worldwide for decades. It was invented by a teacher who used his creativity and love of geometry to design the cube as a teaching tool.

The puzzle was made by Erno Rubik, a Hungarian architect professor and puzzler who created his first puzzle in 1974. The original puzzle was a 3D cube made up of 27 smaller “cubies.” These cubies were made out of wood and were originally part of craft materials used in Rubik's classroom. Rubik experimented with rubber bands and wooden blocks to create a geometric puzzle. In the process, he unknowingly invented what would become an iconic brain teaser, originally called the Magic Cube.

The classic 3x3 Rubik’s Cube is made up of 27 smaller cube pieces, or “cubies,” arranged around a hidden central core. Each of its six sides is a different color. When scrambled, the colors are jumbled and scattered across the cube, making it look mismatched. The goal is to twist and rotate the layers until each side of the cube shows a single, solid color again. [Read More]

Why Does Blobfish Looks So Strange?

by Yemariam Bekele, age 9

True to their name, blobfish are bulbous, squishy creatures with weak bones. Deep underwater, they are unrecognizable due to the intense water pressure helping them hold their shape together. Their shocking appearance outside of the water has caused some people to coin the blobfish “the ugliest fish in the world.”

The blobfish lives deep in the Pacific Ocean. They can be found in dark and cold environments between 1,970 and 3,940 feet below the surface. Giant squids and angler fish also live in the deep ocean with the blobfish.

The blobfish keeps itself alive by eating crustaceans, which can include crab, shrimp, lobster, starfish, and even dead fish. Blobfish relax at the bottom of the ocean and wait for their prey to come to them. [Read More]

Why Wisconsin’s State Fish Is Called the Fish of 10,000 Casts

by Joseph Zheng, age 10

The muskellunge is the state fish of Wisconsin. This massive fish can grow up to around three feet and weigh about 67 pounds. The scientific name for the muskellunge is Esox masquinongy. However, it has earn the nickname “the fish of 10,000 casts,” because tends to avoid fishing lures and can be unpredictable.

The usual color for the muskellunge is a blend of green to dark green, although it can also be slightly gray. The muskellunge can swim up to 30 miles per hour. Its lifespan is typically about 12 to 18 years, but it can live up to 30 years.

From mid-April to mid-May, the female muskellunge gives birth to between 20,000 to 250,000 eggs. These eggs can stick to woody debris on rocks and sandy bottoms. Parents do not protect the eggs, so most eggs get eaten. [Read More]

Feathers, Fur, and Farmwork: The Role of Domesticated Animals

by Arsema Biruk, age 8

Domesticated animals are animals that humans have tamed. Domesticated animals provide important resources for humans. These animals can be kept as pets, are used as working animals, or serve as a source of food.

Many domesticated animals are raised on farms. These animals can include cows, horses, donkeys, pigs, sheep, and llamas. Other creatures include various types of fish, reptiles, and some invertebrates, such as snails and clams. Some are kept for their ability to work, such as large workhorses that pull heavy machinery or herding dogs that make sure the herds of sheep stay together. Other animals are kept on farms so humans can obtain their milk, meat, eggs, hair, or even their skin. The most common domesticated animal is the chicken, and there are 25 billion chickens today worldwide kept for their eggs and meat. [Read More]

These Long-Necked Antelope Stand Tall in the Wild

by Lucas Abiy, age 8

Gerenuks are not your typical antelope. This species has distinguishable long necks, legs, horns, and large eyes.

In Somali ,the word gerenuk means giraffe-necked. Unlike other four-legged creatures, these unique antelope often dine on two legs. Gerenuks feed on leaves from high places such as high bushes, shrubs, blooms, and shoots. Gerenuks have specialized backbones that help them stand on two legs. They can also reach up to six feet on four feet making them really tall. They can reach things that other animals can’t reach.

Gerenuks live in East Africa in the countries of Kenya, Ethiopia, Somalia, and Northern Tanzania. They prefer to live on semi-arid bush land and dry deserts. They avoid dense forests and open grasslands. Where they can’t see predators from far away. [Read More]

Baby White Rhino Named Nova Brings Hope for Conservation

by Isabella Flores Gonzalez, age 7

A baby white rhino was born in Belgium and named Nova, marking a significant moment for conservation efforts. She was first shown to the public in February 2024.

After her birth, the calf was cared for by the zoo staff. Although Nova was initially nervous, her mother’s presence made her feel at ease.

White rhinos are very large animals and eat about 120 pounds of grass per day. The southern white rhino lives in South Africa and can live up to 50 years. Even though they are called white rhinos, they are usually not white but tend to be gray or brown. They can survive up to five days without drinking water and five to seven days without food. White rhinos are the largest rhino species, growing 12 to 15 feet from head to tail. There are two types of white rhinos, including northern white rhinos and southern white rhinos. [Read More]

Capybaras Are the World’s Largest Rodents

by Delia Moreno, age 7

Capybaras are the largest rodents in the world. They can be found in Southern and Central America inside rainforests and near ponds, rivers, and lakes.

Capybaras are semi-aquatic animals. They grow up to 1.5 feet tall by the shoulder, 4 feet in length, and weigh around 75-150 lbs. Water is important to capybaras because it helps them hide from predators such as jaguars, anacondas, caimans, pumas, and ocelots. Their webbed feet help them move and relocate easily in the water. They eat grass and aquatic plants. Capybaras also eat their droppings, which is an activity called coprophagy. [Read More]

Sea Turtles Are Gentle Giants of the Ocean

by Semaia Zeregezhi, age 10

Sea turtles are tranquil, loving reptiles, and they can range in size from small to absolutely massive. The largest sea turtles can weigh more than eight people combined! Their shells consist of an upper part called a “carapace” and a lower section called a “plastron.” Hard scales, also known as “scutes,” cover all species of turtles except leatherback turtles.

There are six different species of sea turtles. The Olive Ridley turtle normally weighs less than 100 pounds. The leatherback usually ranges from 650 to 1,300 pounds. The carapace of each turtle ranges in color, length, shape, and arrangement of scales. The plastron is located beneath the sea turtle's stomach. [Read More]

Bees and Wasps Are Similar Yet Surprisingly Different

by Dellany Onyango, age 9

Bees and wasps are winged insects that share many similarities but also have distinct differences. Both insects have a proboscis, a specialized mouthpart that helps them drink water and nectar. Female bees and wasps have an organ called an ovipositor, which can be used for either laying eggs or, in some species, as a stinger. Since male bees and wasps don’t lay eggs, they do not have an ovipositor and, therefore, cannot sting.

Bees and wasps are found on all continents except Antarctica and can thrive in various environments, from deserts to grasslands. Their diets mainly consist of nectar and pollen, but some wasps are also carnivorous, feeding on small invertebrates such as caterpillars and spiders. [Read More]

Giraffes Are Graceful Animals of the African Grasslands

by Isabella Flores, age 7

Did you know that baby giraffes are known as calves? These calves are about six feet tall when they are born!

The scientific name for a giraffe is giraffe camelopardalis. These animals are herbivores which means their diet consists of plants, grass, leaves, and fruit. These mammals can weigh up to 1,750 to 2,800 pounds, and can grow up to 19 feet tall!

Calves commonly die due to lion attacks during the beginning of their lifespan. Adult giraffes can protect themselves due to their height. Along with their height, giraffes have long tongues, necks, and strong legs for running. For giraffes to stay safe, they need to be mindful of their surroundings when bending down to rest or drink water. [Read More]

Cómo las plantas acuáticas sobreviven en el agua

por Semaia Zerezghi, edad 9

Las plantas acuáticas son plantas que viven en el agua. Estas especies viven en el margen de estanques, ríos y pantanos. Un ejemplo de este tipo de plantas es la Vallisneria spiralis, una planta oxigenante, que suele estar en estanques y acuarios.

Muchas de las plantas acuáticas se encuentran bajo el agua, pero también hay algunas expuestas al aire. El pequeño sistema de raíces sirve para anclar la planta y para directamente absorber el dióxido de carbono y los minerales del agua. Algunas plantas que están bajo el agua contienen bolsas de aire que les ayudan a sobrevivir en estas condiciones. [Leer más]

Three Wisconsin Birds that Weigh Less than an Ounce

by Joseph Zheng, age 10

Wisconsin's smallest birds can weigh less than a pencil. The Downy woodpecker, American goldfinch, and house sparrow are all examples of small birds commonly found in the state.

The Downy woodpecker is 11 to 14 centimeters long and typically weighs around 20 grams. These woodpeckers are frequently seen at bird feeders, where they enjoy suet, sunflower seeds, peanuts, and even peanut butter. Downy woodpeckers are also fond of drinking sugar water. They produce high-pitched calls that are easy to recognize, along with rapid drumming sounds created by tapping their feet during mating displays, which can sound continuous due to their speed.

Humpback Whales Are the Big Singers of the Ocean

by Isabella Flores Gonzalez, age 7

The humpback whale is a marine mammal found in oceans around the world. These massive creatures can grow as long as 50-60 feet and weigh as much as 40 tons, making them one of the largest animals in the sea.

Humpback whales have a diet that includes krill, small fish, and other small marine organisms. Instead of teeth, they have baleen, comb-like structures in their upper jaws that help them filter food from water. When feeding, a humpback whale opens its mouth wide, allowing water and small prey to enter. It then uses its tongue to push the water out through the baleen, trapping the prey inside to be swallowed.

In addition to their unique feeding technique, humpback whales are remarkable for their ability to hold their breath for up to 30 minutes during deep dives, although they typically stay submerged for around 10-20 minutes. They are also famous for their songs, which can last up to 15 minutes and are believed to be part of mating displays. [Read More]

Why Snow Leopards Are Called Ghosts of the Mountains

by Sessina Zerezghi, age 7

Snow leopards, also known scientifically as Panthera uncia, are interesting animals. They are similar to lions, pumas, and other big cats. Unfortunately, these leopards are endangered.

Snow leopards live in 12 central Asian countries, some including China, India, Nepal, and Russia. Snow leopards have many abilities that help them survive extreme cold weather. These mammals have a tail that measures up to 36 inches. They weigh between 60 to 120 pounds. Snow leopards also have beige fur that helps them blend in with the rocks and terrain in their environment. The spots on their coats help them camouflage into their environment.

Snow leopards have only been seen by a few people, which is why they are known as the “ghost of the mountains.” Since these leopards are rarely spotted, researchers believe there are only about 3,500 to 37,000 snow leopards left in the wild. These cats are endangered because their food, like wild sheep and ibex, is constantly being hunted. Researchers use satellite radio collars to track where snow leopards travel. [Read More]

Learn All About the Unicorns of the Ocean

by Reety Subedi, age 8

Narwhals are popularly known as the “unicorns of the sea.” However, they are scientifically known as Monodon monoceros.

Narwhals eat flatfish, cod, shrimp, squid, and crab. Their food is found during their long dives. Narwhals use echolocation to locate their prey and they can dive down more than one mile deep in search of their food. It is unknown if their tusk is helpful during hunting or feeding.

Narwhals have a sausage-shaped body, round head, and no beak. Babies are dark gray, adults are gray and white, and older ones are white. Instead of a dorsal fin, narwhals have ridges located on their back and tail flukes that curve backward giving them a unique appearance adapted to life in Arctic waters. A well-known feature of the narwhal is their tusks, which can grow up to ten feet long. The tusk that narwhals grow is also considered a tooth. This tooth helps them feel or taste. [Read More]

The Mysterious Giants That Shape Our Galaxy

by Aloniab Gezae, age 10

A black hole is a region in space with an extremely powerful gravitational force. Black holes aren’t holes; rather, they are composed of extremely dense material packed into a tiny space, creating a remarkable force that pulls everything inward. This gravity draws in anything that comes near, and it is so strong that even light cannot escape. Black holes are called “black” because they are invisible in space.

There are two types of black holes, a supermassive and a stellar. Supermassive black holes are the largest, with masses millions of times greater than that of the sun. The black hole at the center of our galaxy, known as Sagittarius A, is a supermassive black hole that plays a crucial role in influencing the motion of stars around the center of the Milky Way. The most common type of black hole is the stellar black hole, which forms from the collapse of a massive star and can be around 20 times the mass of the sun. [Read More]

These Big Cats Are Often Mistaken for Otters but Are Stealthy Predators of the Americas

by Lucas Abiy, age 7

The jaguarundi cat is an amazing creature. Due to their small stature and slender-long body, these wildcats are commonly mistaken for weasels or otters.

The jaguarundi cat has sharp canines and carnassials to rip up flesh from their prey. This cat feeds on amphibians, small birds, mammals, reptiles and fish. These creatures have rough tongues with small bumps called papillae to collect the remaining flesh off bones.

The jaguarundi weighs around five to nine kilograms; its body is about 55-77 centimeters, with its tail being 33-60 centimeters. They have soft pads on their feet covered in thick hair that allow them to grip onto trees and stalk their prey silently through the dense forest. These cats have ear flaps that can focus on sounds and enhance hearing. [Read More]

Mallard Ducks: Beloved Residents of Wisconsin’s Waterways

by Joseph Zheng, age 10

In Wisconsin, mallard ducks are very common, especially near water. They are so common that the “Madison Mallards” is the name of a Wisconsin baseball team.

Mallards might plant nests in your roof, flowerpot, or chimney. Be cautious and prepared whenever they come and make a home out of your belongings.

Mallard ducks have big, round heads and flat, wide bills. This duck has a wingspan of about 32 to 37 inches and weighs about one to four pounds. Mallards support their diet with dragonflies, larvae, and gastropods, but the most common food source that mallard ducks eat all year long is grain from crops. Occasionally, they might eat small fish, but their diet mainly comprises plants and small invertebrates. Mallard ducks are nicknamed “Dabbling Ducks” because they tip forward in the water to reach aquatic plants and insects, rather than diving deeply. [Read More]

The Largest Leopard in the World Stalks the Forests of Iran

by Ermiyas Abiy, age 9

The Persian leopard, also known as the Caucasian Leopard, is a highly rare animal found in Iran. For decades, it has rarely been spotted outside of this country. Generally, these leopards have only been occasionally spotted and were thought to be extinct outside of Iran. However, while the majority of Persian leopards live in Iranian forests, some also inhabit regions of Afghanistan, Russia, Pakistan, and Turkey.

Persian leopards are the largest subspecies of leopard in the world. The leopard lives in forests, but due to their rareness, little is known about them. Furthermore, their low populations have initiated the development of leopard reserves in several countries.

Female leopards are viviparous which means the propagates already start growing before they are out of their mom’s stomach. They leave their mothers when they are 18 to 24 months old, but before they leave, their mothers share valuable hunting skills with their cubs. They do this by bringing them on a hunt when they are only three months old. [Read More]

How Will the Universe End?

by Abigail Gezae, age 10

Nobody knows the fate of the universe, but there are many possibilities. For example, dark energy might become so strong that it overpowers all forces including gravity. If this happens, the expansion of the universe will grow faster and faster as it is pushed apart without any limit. This theory is called the “Big Rip.”

The “Big Rip” results in galaxies, stars, planets, and all life being torn apart, but it’s also possible that the universe just keeps expanding. If dark energy stays indefinitely the same force as it is today, space will keep growing and may never come to an end. Additionally, another possible end for our universe lies trillions of years in the future.

Eventually, after the universe expands too much, no heat will be able to be spread and the temperature could drop to its lowest possible point. This will be known as the “Big Chill,” meaning no life could survive. [Read More]

Gila Monsters: The Venomous Predators of the Desert

by Ermiyas Abiy, age 9

Gila monsters are one of seven venomous lizards that exist in the world. They are some of the rarest creatures but are also endangered.

Gila monsters have many interesting features. One of its most notable features is its poisonous bite and venom. Gila monsters have bacteria in their mouths which can cause infections to its prey upon attack. Along with the bacteria, their venom is fatal to most small animals like reptiles, rabbits and rodents. Gila monsters have unique color patterns consisting of black, brownish-yellow and red. These color patterns help them camouflage from predators. Additionally, their bony and bead-like scales act as effective protection and armor.

While the Gila monster has many strong protective features, one of their weaknesses is in their vision. Their eyes are small and inefficient, thus they rely on other senses for practically everything. [Read More]

Arabian Camels: Man's Best Friend?

by Joseph Zheng, age 9

Owning a camel can be a sign of wealth in other countries. Dromedaries, better known as Arabian camels, are unique mammals with distinct characteristics.

Dromedaries are heavy animals weighing up to 1,600 pounds and grow to seven feet tall. A main characteristic you may notice on dromedaries is the big humps on their backs. Their humps are unique because they store 80 pounds of fat which can be used for hydration in the future. The Arabian camel is also able to consume 30 gallons of water in 13 minutes! Because of their strong features, they are able to carry heavy loads for 25 miles a day.

Arabian camels can be found in various places around the world. Many live in Northern Africa, Southwestern Asia and Australia. These locations can reach very high temperatures, but the camel's body is trained to survive temperatures reaching 120 degrees Fahrenheit. [Read More]

Nature’s “Vacuum Cleaner:” The Matamata

by Aarosh Subedi, age 10

The matamata lives in South America and is part of the turtle family. The matamata lives in the northern part of South America, in Brazil, Venezuela, but can sometimes be found in northern Bolivia, Ecuador, eastern Peru, Colombia, the Guianas, and Trinidad. They are about 18 inches in length and weigh around five to six pounds. Other than eating fish, they eat small birds and small mammals. This particular species lives up to 30 years.

Scientists compare this species to a vacuum cleaner, because it swallows its food rather than chews it. Camouflage is a common hunting tactic for the matamata. When in hunting position, it looks like an unassuming mossy rock in the water. They have fleshy appendages close to their mouths that look like weeds hanging and can act as a lure for fish. The nose on the matamata acts as a snorkel, allowing them to breathe air while they wait for food to approach so they can swallow it whole.

The word matamata is a phrase in a Native language that means “I kill” and its scientific name is Chelus fimbriatus which means fringed turtle. A matamata’s neck is almost the size of its back. In comparison, if the same were true for humans, our necks would be about three feet long. The matamata is one of the turtle species that breathes air, unlike other turtle species who get oxygen from water. [Read More]

Learn About the Vampire Squid

by Abigail Gezae, age 10

Vampire squids don’t actually share many resemblances to Dracula, and they aren’t after your blood. Instead, they are creatures that live deep in the ocean, around 2,000 to 3,000 ft.

Since the vampire squids live so deep in the water, scientists have to use drones to study them. They have very large eyes which are located on the side of their head, and are usually red or blue, depending on the light they reflect. Although they have the characteristics of other squids, they have 8 legs like an octopus and other cephalopods. One notable difference: vampire squids can not change color or use ink to protect themselves, which means they have to use different methods to stay safe. [Read More]

Leopards Are Large and Powerful "Supercats"

by Ian Kosharek , age 10

Leopards are a type of cat that live mainly in Africa, but they can also be found in China, Malaysia, and even Korea. There are more leopards in the wild than any other wild cat—that is why they are called supercats!

Leopards prefer to hunt at night, sitting in tree branches and waiting for their prey to come close. They are patient and let their prey get near in order to successfully attack. Leopards are pretty strong and can even lift prey as big as themselves.

Leopards enjoy eating animals of all sizes, from dung beetles, frogs, and birds, to monkeys and antelopes. Hyenas compete for similar foods, but leopards are selfish and do not like to lose their food to competitors. In order to keep their food safe they hide it in trees, which is known as caching. Some leopards are known as panthers. This name is only given to leopards that are born with black fur instead of their normal brown fur. Although leopards are the most common wild cat, they are quick and quiet so you may never know if one is following you! [Read More]

Is That a Leaf or a Gecko?

by Aloniab Gezae, age 8

The leaf-tailed gecko is a fascinating reptile. It can only be found in the rainforests of Madagascar and can grow up to eight inches long. Since leaf-tailed geckos are extremely rare, their lifespan is still unknown to scientists.

The gecko’s body is small and flat which makes it easier for it to fit in tight spaces for protection. It also has a long and sticky tongue that helps it catch prey, such as insects, spiders, and other invertebrates. Since they do not have eyelids, these creatures also use their long tongue to help clean their eyes.

Each toe of the leaf tailed gecko has millions of tiny bristles that help it get a good grip on both big and small surfaces. Similarly, its strong and flat tail also has bristles, which these geckos often use as an extra foot to help with balance. [Read More]

The Arduous Life of Monarch Butterflies

by Sol-Saray, age 10

Did you know that it takes three generations of monarch butterflies to get from Wisconsin to Mexico in a year? It's incredible how long these little butterflies can fly!

The adult monarchs do not care for their babies after they give birth. They give birth on the milkweed plant and the newborn caterpillars survive on their own. After the parents die, the newborn butterflies continue their journey to Mexico. The lifespan of these monarchs is from two to six weeks.

The monarch butterflies stay in Wisconsin for spring and summer. Afterwards, they start their journey to Mexico for the winter to find warmth. They are in Mexico from November to March just in time for Dia de los Muertos. [Read More]

How Bees Make Plants Grow

Pollinators are very important on our Earth. You would be surprised at how much bees and pollinators help. Did you know that we need pollinators so much that flowers depend 80 percent on pollination?

Wonder where flowers come from? While water and nutrients from soil help them grow, pollinators also help too! You might not notice these small insects, but they come by and play an important role in pollination. If there were no pollinators, the human race would not be alive and the Earth would not have as many beautiful flowers as you see today.

Pollinators don’t just pollinate flowers! They also pollinate plants and vegetables. These plants include blueberries, strawberries, raspberries, and more. Do you enjoy tea with honey? Well, pollinators such as bees are responsible for honey production! [Read More]

The Secret Life of Pollinators

by Dilma Attidekou, age 8

A plant has a lot of needs in order for it to be healthy. These needs include water, sun, and soil. Insects like the yucca moths, bumblebees, and honeybees take the pollen and nectar from plants.

In order for insects to get nectar and pollen, they need to feed on the nectar inside a plant. The pollination, yucca plants, and pollen grains are some seeds from different plants that insects take. Female yucca moth impersonators take the yucca pollen from the yucca plant and bring it to their home. However, not all moths do this.

The inside of a flower can be pretty fascinating as it has a stigma, anthers, nectar, and pollen. That's how insects are able to feed on the nectar and pollen. When a bumblebee gets nectar, the flower closes and the bee has to push open the flower. Afterwards, the bee is able to get the nectar as the pollen comes up. [Read More]

Did you know butterflies have an important role in pollinating flowers? They especially like flowers that have a strong scent, contain certain colors such as red and yellow, or plants with plenty of nectar.

While butterflies can be easily seen in the air, they didn’t always start out this way. Butterflies begin as caterpillars. Over time, these insects undergo metamorphosis, a process in which they create a cocoon to transform into butterflies. Once they come out the cocoons, it takes time to learn and get used to flying.

An important type of butterfly is the Monarch Butterfly, also known as the Painted Lady. It gets its name from its black and orange colors. Monarch butterflies weigh the same as a paper clip and can grow up to four inches. They also have a lifespan for 15 to 29 days. In the winter, Monarch butterflies migrate 1,700 miles to Mexico to avoid the chilling temperatures of Wisconsin before returning during warming seasons. Monarch Butterflies lay their eggs in May or June on a poisonous plant known as milkweed. When their larvae hatch, this plant serves as a food source and in the process, the butterflies can become poisonous as they continue feeding. [Read More]
