Mesmerizing Fractals

STEM Activity

1 review

Do you ever wonder what mathematicians study, and why? Most of what they do is complex and inaccessible to laymen, but fractal art might give us a glimpse. While mathematicians study fractals formally, they are used in many branches of science and technology, and we, as laymen, are struck by their beauty. Are you eager to create one? In this activity, you will get to take out some finger paint to make artwork and discover how common fractals are. Read more

Milk Curdling with Enzymes!

STEM Activity

43 reviews

Have you ever gone to pour yourself a cup of milk, and all you get is clumps? What happened to the milk is called coagulation, which is the mechanism that occurs when proteins in the milk clump together. While you do not necessarily want this in your milk, without coagulation (or curdling), there would be no cheese or yogurt, which is why it is a very important process in the food industry. Wonder how you can make milk curdle? Do this activity to find out! Read more

M&M Geometry

STEM Activity

4 reviews

Has an adult ever caught you munching on candy and asked, "How much candy have you eaten?" Instead of saying, "I don't know," and possibly receiving a scolding, wouldn't you rather respond, "I ate precisely 10.7 cubic centimeters of candy"? In this activity, you will investigate which mathematical formula is most accurate for estimating the volume of an M&M. Figure this out and the next time you are discovered while snacking on sweets, you might make a… 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

Model How Herd Immunity Works

STEM Activity

22 reviews

Have you ever wondered why you need to get a flu shot regularly? The vaccine protects you from getting sick with the flu, which is an infectious disease. Such diseases, like the flu or COVID-19, can easily spread through a population and cause a pandemic by making many people sick. Measures such as social distancing can reduce the risk of catching the disease, but real protection only comes from gaining immunity against the disease. This is the reason for vaccinations—to make someone… Read more

None of Your Fizz-ness – Make Your Own Sherbet!

STEM Activity

1 review

Did you know that if you could take the acid in your stomach and put a few drops on a wooden table, your stomach acid would eat right through it? The acid in your stomach is as powerful as battery acid! Luckily your stomach isn’t damaged by this powerful acid, because it has special cells that act as a barrier to the acid, preventing it from breaking down your stomach tissue. These cells produce a basic mucus that neutralizes the acid in your stomach. Turns out, your stomach is a pretty… Read more

Paper Squawker

STEM Activity

7 reviews

Did you know that not all animals use their ears to ‘hear’ sounds? Snakes, for example, perceive sound waves through their jaw bones! And many insects perceive sound waves through their antennae. While these methods of detecting sound might be different, they all respond to the same thing that our ears do, which is sound waves in the environment. In this activity you will generate some impressive sound waves from very simple materials, and observe how these sound waves are… Read more

Password hacker

STEM Activity

10 reviews

Do you have your own email or social media accounts? If so, you probably use a password to log into them. How did you pick your password? Is it something that might be easy for someone else to guess, like the name of your pet? This fun activity will teach you about password security and how to pick a stronger password. Read more

Phone Book Friction

STEM Activity

24 reviews

A popular science demonstration shows that when you overlap the pages of two phone books, they are nearly impossible to pull apart. Since most people do not have two phone books sitting around, we will show you how you can do the same experiment with sticky notes. Sticky notes are much smaller than phone books, so they should be easy to pull apart, right? Try this activity to find out! Read more

Physics Secrets for Hula Hooping

STEM Activity

6 reviews

Have you ever spent time spinning a hula hoop around your waist or arm? Could you easily do it, or was it difficult? Have you ever wondered how hula hoops work, or, in other words, what makes them be able to spin around a person's waist or arm? It comes down to the physics that is involved. Physics can help you determine what makes one hula hoop a winner and another a flop. In this activity you will get to create your own hula hoops and investigate how their masses affect how they spin. … Read more

Pinocchio’s Arm: A Lie Detector Test

STEM Activity

9 reviews

Did you ever think of lying as an interesting social skill? Lying is actually tied to empathy, the ability to see things from another person’s perspective. Most humans begin to develop these skills around the age of three, when they begin to understand that what they know about the world might be different from what other people know about the world. Telling lies might be a skill, but lies can be bothersome. Sometimes, you really like to know how to tell a truth from a lie. Will the… Read more
