You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if...

This video provides an introduction to basic concepts in magnetism, including magnetic poles, magnetic fields, and electromagnets.

How well do you wash your hands? Do you just give them a quick rinse with water, or do you use soap? Do you wash the backs of your hands and in between your fingers? Good hand washing is one of the best ways to prevent the spread of...

Have you ever wondered where rain comes from and what clouds are made of? You can find the answers to these questions by making a miniature water cycle model in a plastic bag. Follow the instructions in the video and see how you can make...

Would you like to include LED lights in a painting or greeting card? This video will show you how. Paper circuits are made with just a few simple items; you can use a battery and some copper tape to add tiny lights to your project. The...

Rube Goldberg machines—machines that complete a simple task in a convoluted way—are intriguing, artistic, and fun! If you ever wanted to make one, this video will show you how the concept of kinetic energy can help you design and build...

When should you use the Scientific Method? Would the Engineering Design Process be a better choice? If you aren’t sure then this video can help! We compare both methods step-by-step using a real-world example.

How do engineers solve problems? They use the engineering design process to create the best possible solution. In this video, we will show you how to do it step-by-step as we prepare to send our eggstronaut on an interplanetary mission.

In this activity, you will use recyclable materials to make your own wall marble run. A marble run is a fun toy and a great way to learn about physics concepts like kinetic and potential energy. Do you think your marble will make it to...

We breathe a lot, roughly 12 to 16 times a minute for adults and even more for children! Have you ever wondered how the process of breathing works so smoothly? Our lungs allow us to inhale the oxygen our body needs, but they do much,...

Do you love playing on a seesaw? Why is it that depending on where you sit on the beam, and the weight of the person on the other side, you either fly up into the air or fall down to the ground? And why is it so difficult to perfectly...

Bridges come in all shapes, sizes, and materials. What makes a bridge the strongest? Find out in this fun activity as you build simple bridges with paper and test to see how much weight they can hold.

There are many occasions to light candles. When you did, have you ever looked closely at the flame? Which part of the candle is actually burning? Can you tell? Is it the wick, the solid wax, the liquid wax or something else? In this...

Have you ever wondered what a parachute and an open rain jacket have in common? They both trap air and slow you down when you move fast! In this activity, you design a parachute for a miniature action figure. Tissue paper or a plastic...

It's time to set sail! Even if you live nowhere near a lake or ocean, you will get to do some sailing in this science activity as you build your own toy sailboat. But first, you have to make sure your boat doesn't capsize! Are you up for...
