Learn About Wisconsin’s Largest Lake

by Ermiyas Abiy, age 9

Wisconsin's largest lake is well known for hosting some of the state’s most popular fishing events.

Lake Winnebago is approximately 137,700 acres and the perimeter of the lake is about 88 miles. The depth of the lake reaches 21 feet, which is exactly seven yards deep.

Lake Winnebago formed after the Ice Age and after glaciers went away from Wisconsin. This giant lake formed from the remains of Glacial Lake Oshkosh 12,000 years ago, and Native Americans started to settle on the coast of Lake Winnebago. [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]

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 San Francisco Built the Golden Gate Bridge

by Lina Al Quraishi, age 10

Spanning one of the largest and safest harbors in the world, the Golden Gate Bridge is 1.7 miles long and has been in use for 87 years. The Golden Gate Bridge opened on May 27th, 1937, linking San Francisco with Marin County, California. The bright red color of the bridge, known as "International Orange," allows for easy visibility even during foggy or rainy weather.

The person who designed the bridge was Joseph Strauss, the chief engineer responsible for its construction. He was assisted by a consultant, Irving Morrow, who contributed to the bridge’s Art Deco design and the choice of its iconic color. [Read More]

What Is Bluetooth? Exploring Its Uses and Security Tips

by Aarosh Subedi, age 11

Bluetooth is a form of technology that connects devices without the need for cables or wires. There are several interesting aspects of Bluetooth.

Through Bluetooth, multiple devices can communicate with each other. Bluetooth capability in devices is now commonly an electronic “standard,” meaning manufacturers and companies typically incorporate specific requirements to allow other devices to interact with and recognize their products via Bluetooth.

A large number of personal electronic devices (PEDs) utilize Bluetooth technology. For example, people can operate computers with a wireless keyboard or use a wireless headset for phone calls. These are just a few examples of Bluetooth technology in daily life. [Read More]

Colugos: Incredible Gliders from Southeast Asia

by Delany Onyango, age 9

Although the colugo, a creature that resembles a flying chipmunk, cannot fly, it has the remarkable ability to glide through the air. The colugo has a patagium, which is the stretchy skin that connects its limbs, allowing it to glide between trees.

When fully extended, their patagium can span up to 28 inches, helping them glide distances of up to 328 feet. The colugo can fold up its patagium to avoid getting caught in twigs or other sharp objects and uses its tail to steer while gliding. [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

by Maya Maclin, age 10

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]

Would You Want to Live on Neptune?

by Dilma Attidekou, age 8

Neptune, the smallest out of all outer planets, is known for its blue color. Methane is the reason for its color. Neptune has less then four percent of methane within its atmosphere.

Neptune is very far from Earth, approximately 2.5 billion miles away. Pluto is usually farther from the sun than Neptune, but once every 248 years, Pluto crosses in front of Neptune. The planet has enormous storms, but they don’t last as long as Jupiter's great Red Spot.

Neptune takes 165 Earth years to orbit around the sun. Due to the planet's orbit being almost a perfect circle, its seasons are all of even length. Neptune’s climate and seasons are different from Earth’s seasons. [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]

Explore the Mighty Congo River in the Heart of Africa

by Sol-Saray, age 10

Africa is home to many great rivers. One of them is known as the Congo. In Africa, the Congo is only slightly shorter than the Nile in length, and is just as important to the people who live along the river.

The Congo has been very efficient for the people of Africa when it comes to transporting goods like food, medicine, clothes, and other items to people living along the river. It is also used for fishing and irrigating crops like peanuts, cotton, and sugarcane.

In the river, there are over 30 waterfalls and many other islands. It is near the equator, meaning it can get very hot and wet. The river receives around 90 inches of rain annually. There are 200 species of fish that live on the river. Many animals eat the tall grass that grows along the river, including buffalo, antelopes, zebras, gazelles, and giraffes. [Read More]

Learn More About Wisconsin's Prettiest Pollinators

by Max Moreno Lopez, age 9

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]
