Dye Eggs Using Silk Ties for Egg-cellent Colors

STEM Activity

8 reviews

Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! People often do this using dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. Eggs can be dyed in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this activity, you will dye eggs with silk ties and… Read more

Ears: Do design, size and shape matter?

STEM Activity

16 reviews

Have you ever been puzzled by a faint noise nearby, trying to discover what it is? Maybe you turned your head or cupped your hand behind your ear, hoping to hear the sound better. What if we could make this cup huge? After all, some animals with exceptional hearing have big ears, like a serval (a type of wildcat), which can hear a mouse wiggling its way underground. Birds are even believed to use their entire head as an outer ear. In this activity, you will design and test your newest hearing… Read more

Earthquake Rollers

STEM Activity

10 reviews

Earthquakes can cause serious damage to buildings and even loss of human life. Many of the world’s most populous cities are in earthquake-prone regions. How can engineers keep the millions of people in those cities safe? Find out how you can use science to save lives in this fun activity! Read more

Make String from Algae

STEM Activity

215 reviews

Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more

Energetic Two-Ball Bounces

STEM Activity

8 reviews

How many ball sports can you name? How many of those have several balls at once in the game? Almost none, right? Games that do use several balls at a time most likely use balls of the same mass, volume, and material. Would having two balls of a different mass make a game very difficult? In this activity, you will explore what might happen if you were to add a tennis ball to a basketball game, or a tiny ping pong ball to a tennis game, or any other combination. Ready to be surprised? Try it out! Read more

Evaporative Cooling with Liquids

STEM Activity

1 review

Have you ever wondered why we sweat when our environment is getting hot or when we exercise? Sweating is a life-saving strategy that cools our body down and maintains our body temperature. Without sweating, our body cannot regulate our temperature, which can lead to overheating or even heatstroke. But why does sweating have a cooling effect? The answer is evaporative cooling. Turning a liquid such as sweat from its liquid state into a gas requires energy. This energy is taken from our body, or… Read more

Explore Biodiversity Using a Homemade Bug Vacuum!

STEM Activity

5 reviews

It might seem impossible to estimate how many different bugs live in a nearby field, or how many types of birds live in a forest, but wildlife biologists often have to try to determine the number of different species in a given habitat. This plays an important role in helping us understand how healthy the environment is. In this activity, you will get to take on the role of a wildlife biologist by examining the biodiversity of bugs and other small invertebrates (such as spiders, centipedes,… Read more

Explore How Lung Infection Influences Breathing

STEM Activity

21 reviews

Have you ever coughed, felt short of breath because you were sick, or felt it was hard work to take a breath? Maybe you have watched someone gasping for air. At times, these events can feel scary! This activity explores how mucus and fluid in the lungs or airways changes our breathing using a simple lung model. It can help you understand why symptoms like coughing and being short of breath happen. Read more

Explore Soil Erosion and See What a Plant Can Do.

STEM Activity

26 reviews

You pick up litter, you reduce, reuse and recycle but did you ever consider conserving the soil? It might seem farfetched, but it turns out that soil erosion—or the wearing away of soil by water, wind and other natural forces—is a problem. Productive farmlands can disappear as nutrient-rich topsoil in fields washes away when heavy rains hit them. Waterways can get polluted as pesticides and fertilizers wash into them. Even human life and property are jeopardized, as soil erosion… Read more

Explore the Wet Sand Effect

STEM Activity

8 reviews

Summer is the perfect time to take a stroll at the beach and walk barefoot along the shoreline. While doing that, have you ever looked at your footprints in the wet sand? If so, you might have noticed that with every step it looks like the sand around your feet dries out. Why is that? These dry footprints are caused by the pressure of your feet. You will find out exactly how this happens by doing this beachy activity! Read more

Exploring the Depths – of Vision!

STEM Activity

10 reviews

Did you know that there is a type of clam that has thousands of small eyes covering its body? It’s called the Tridachna gigas, and it lives in the South Pacific Ocean. Although it has a lot of them, the Tridachna gigas’ eyes are fairly primitive compared to ours (so don’t be too jealous that you don’t have thousands of eyes too!). In modern times, all vertebrate animals (including humans) have two eyes. Humans have developed an amazingly complex visual processing… Read more
