Do you remember your last parade, party, or fair? You might have been surrounded by sounds of all kinds: fireworks, music, and, maybe even the famous (or infamous) sound of kazoos. A kazoo is a very simple musical instrument, made up of...

Have you ever wondered what makes the bright colors of fall leaves? You can uncover all of their color pigments with a technique called paper chromatography. This video will show you how to set up and run the experiment yourself!

Find out about static electricity in this STEM activity and measure which materials get charged the easiest with the help of a homemade electroscope!

Scientists study earthquakes so we can understand them better and hopefully one day predict them so we can save thousands of lives. A seismograph is a tool scientists use to record earthquakes and measure their strength. In this activity...

Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? DNA is the genetic instructions for how an organism develops and functions. This video will show you how to extract enough DNA from...

Springtime is when nature comes back to life. Trees are growing their leaves again and flowers are sprouting, displaying their beautiful colors and spreading their delightful smell. But have you ever looked at a flower in more detail?...

This video shows how to use a few simple materials (lightbulb, batteries, and alligator clips) to create a circuit to light up a lightbulb. From there, the video shows how to use the circuit to experiment and determine if various...

In this video, you will see how you can use reflective surfaces to redirect a light beam to wherever you need to if you place the mirrors correctly. Can you use what you learned to guide a light beam through a maze and around obstacles...

Have you ever visited a house of mirrors and seen a wacky-looking version of yourself? In this activity you can construct your own miniature house of mirrors. Try it out and see what funny reflections you can make!

You have probably cracked open a soda before to see the liquid fizz right up out of the bottle, creating a huge mess. Why does that happen? It has to do with the carbon dioxide gas that is added to the liquid to make it fizzy. Opening...

How long do you think you could survive without drinking any water? Only three to four days! Your body needs water to function properly. We also rely on water for cooking, cleaning and many other activities. You might not think about...

This tutorial shows you how to use a solderless breadboard to build an electronic circuit, including the basics of how a breadboard works and some common mistakes that beginners make.

Explore engineering and potential and kinetic energy by building and testing your very own toy car.

How much energy does a roller coaster need to go through a loop without getting stuck? Build your own marble roller coaster in this project and find out!

Have you ever wondered what DNA looks like up close? DNA contains the genetic instructions for how an organism develops and functions. It stores all this information in its unique double helix structure.This video will show how you can...

Have you ever wondered why ice cubes in your cold drink become gradually smaller, or why their surface becomes smoother as they melt? Does ice always melt this way? In this activity, you will use water balloons to create giant ice balls...

Do you know what enzymes are? Enzymes are like little machines that help carry out and speed up chemical reactions. In our body, for example, enzymes help break down the food we eat. This video shows how you can use a toothpick model to...

What is an easy way to move liquid from one place to another? A siphon! With just a little effort to get it started, you can then sit back and watch liquid flow from one container to another, as it seemingly defies gravity by going...

Have you ever ridden a roller coaster? Have you ever wanted to design your own? There are plenty of expensive toys and even video games that will let you build your own coasters—but in this project you'll make one out of paper and...

Explore interplanetary space travel with an experiment! The gravity assist or "slingshot" maneuver is often used by engineers to send spacecraft to the outer planets. This video presents a model to simulate a planetary flyby using...

This video will show you how to use a multimeter to measure voltage, current, resistance, and continuity. This is a beginner's guide aimed at students and electronics hobbyists who need to make basic measurements using an entry-level...

Here's a challenge: Try throwing a paper airplane by moving just your wrist (don't move your elbow or shoulder). It's hard, isn't it? How could you get a paper airplane to fly far if you can use only a short distance to launch it? Try...

Have you ever seen a mobile? Not a mobile phone, but a hanging art sculpture. You might have had such a mobile in your room when you were little. These mobiles hang from the ceiling and are usually made up of many layers of rods to which...

Do you think plants can grow without soil? If you've tried growing veggies, you probably planted the seeds or seedlings in soil. Soil gives the plants the nutrients they need to grow. However, plants can grow without soil too, using a...
