Ant-tastic Teamwork!

September 25, 2024

Ants have been around for millions of years. They were found in fosssils over 100 million years old! They are a type of insect. Across 12 000 different species of ants range different shapes, sizes and appearances.

Ants are impressive in many ways, but especially in their strength. A single ant can carry 50 times its body weight. However, when ants work together their feats are even more incredible. For instance, fire ants have been seen making large rafts made of their own bodies during floods in the south of the U.S. In Central American forests, you can see army ants create a hanging, temporary nest where they can protect themselves.

The key behind the ants’ amazing feats are communication and organization. Ants are a social animal species, meaning they live together in communities containing thousands of ants. Each type of ant has a specific role. A species commonly known as paramedic ants will go on raids to capture prey to eat. During these raids, ants will get injured. Rather than leaving them behind, other ants will bring the hurt ants back to the colony where they can recover and get better. Some will take care of the brood while other ants will defend the colony against attackers. Every colony has what’s known as the queen ant, who makes up her own team, as the producer of eggs.

Working together, each ant has a role in keeping the colony alive and well. As strong as an individual ant is on their own, together they are powerful.



The Hubble Telescope – Photographing Worlds Beyond

December 19, 2023

Telescopes have been used for centuries to explore the vast and dark night sky, allowing us to see faraway objects like stars and planets. The first telescopes used lenses, curved clear pieces of glass, to focus light from stars into an image our eyes can see. Nowadays, most telescopes are built with curved mirrors, which are lighter and easier to make.

However, Earth’s natural and man-made elements, such as rain clouds, lights, and the Earth’s atmosphere, interfere with seeing into space. In the 1920s, scientists began discussing the possibility of launching a telescope into space. After decades of research, fixing problems, and getting enough money, the Hubble Telescope was launched into space on April 24, 1990. The telescope has been used daily to observe our universe and take photographs, uncovering many secrets of the universe.

One photograph from 1995 showed a part of the sky that looks empty to our eyes but actually contained more than 3,000 galaxies. A galaxy is a massive collection of gas, dust, billions of stars, and planets held together by gravity. The Milky Way galaxy, shaped like a massive flat spiral, is home to our Solar System and the Sun, one of its many bright stars.

The Pillars of Creation

The “Pillars of Creation” capture colourful gaseous blobs from which new stars are being born, something we would never be able to see with our naked eye. With advancements in technology, we can continue to study, share, and admire the wonders of the universe.

Gingerbread Houses

December 12, 2023

Gingerbread has been delighting taste buds worldwide for centuries. Gingerbread likely came from the middle East or Asia, where people have been making it for over a thousand years. Legend has it that gingerbread arrived in Europe in the tenth century where a monk named Gregory Makar brought the recipe from Armenia to France.

As the treat became more popular throughout Europe, gingerbread shaping became an art form. People would carve a picture into a piece of wood and press dough into the mold, and their cookies would look like the picture.

After the Brothers Grimm wrote the story of Hansel and Gretal, Germans began to make gingerbread houses just like the one in the story. Later, when Germans immigrated to America, they brought this tradition along with them for many Americans as well.

Every winter, in the city of Bergen Norway, children ages eleven and under are invited to build an entire city of gingerbread. This magical display is called Pepperkakebyen, which means gingerbread town.

Simone Biles

November 14, 2023

Simone Biles is widely considered the greatest gymnast of all time. She is the first female to win three straight All-Around World Championships, earning a total of 14 medals, 10 of them gold.

Life was not always easy for Simone. Her birth mother was unable to care for her children. Simone’s grandparents, Ron and Nellie Biles, adopted Simone and her younger sister, Adria.

On a field trip with her daycare class, six-year-old Simone was introduced to her sport at Bannon’s Gymnastix. Very quickly, she started copying the gymnasts, drawing the attention of the instructors.

“I loved the idea of flipping around, and the center saw something in me, so they sent home a letter to my parents encouraging me to join,” Simone explains. “Right from the start, I was fearless and willing to try anything and everything.”

Simone advanced very quickly. At age seven, she began performing competitively. Her debut as an international gymnast was on March 2013 at a World Cup event.

Simone is known for her power and upbeat personality. She often plays to the crowd, flashing a big smile as she performs in the floor exercise. Her coach, Aimee Boorman, appreciates her hard work and personality. “Simone is bubbly. She loves to laugh, is genuine and real. When she wins and is given flowers on the medal podium, she searches out the shyest child in the crowd and gives her the flowers.”

How does Simone handle the pressures of life as an athlete? “It is important to embrace the moment,” she says. “Remember to have as much fun as you can, but keep in mind, win or lose, you still have your whole life ahead. You can achieve anything that you put your mind to.”

Making Artificial Limbs

November 7, 2023

A pirate’s wooden leg may be one of the most famous examples of an artificial limb. These are devices that replace a body part. But did you know that there are records of replacement limbs as far back as 200 BCE? In Ancient Rome a famous general named Marcus Sergius was said to have a hand made of iron. Unfortunately for the general, his hand couldn’t do much. He wore it as decoration.

In the American Civil War, many soldiers lost limbs from fighting. Scientists and engineers began to design replacement arms and legs to do work. One design helped injured soldiers grasp things with moveable fingers. It was one of the first examples of a controllable artificial limb!

There are many reasons someone might need an artificial limb today. Perhaps they were born without an arm or leg or they were injured and had to have their arm or leg removed in surgery. Scientists and engineers are concerned with making them comfortable for the person and making it act like the original limb as much as possible.

There are also many different types of artificial limbs today for many different purposes. They can be steel arms, legs molded to look like a person’s original legs, or even blades that runners use to compete in races!

The most advanced artificial limbs today work with a wearer’s body and brain to imitate how a normal limb works. This lets the person control the limb with their brain, just like they would with any other part of their body.

Thankfully, artificial limbs have improved a lot since the days of pirates and their wooden legs. We can all say “aye!” to that!
