10 Fun Science Experiments for Kids

You've seen for yourself, or in videos, planes flying, rockets hurdling towards space, boats racing through the water and submarines exploring the depths of the ocean. Have you ever stopped and thought about the aerodynamics and hydrodynamics involved in their operation? There is a lot of interesting science that goes into how they work!

Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more

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 this activity to find out! Read more

Blast off! Have you ever played with a model or toy rocket, or seen a real rocket launch on TV? In this project you will make simple rockets out of paper and launch them by blowing into a drinking straw. Can you make the rocket that flies the farthest? Read more

Just one sheet of paper can lead to a whole lot of fun. How? Paper planes! All you have to know is how to fold and you can have a simple plane in a matter of minutes! But what design should you use to build the best plane? In this aerodynamics science project, you will change the basic design of a paper plane and see how this affects its flight. Specifically, you will increase how much drag the plane experiences and see if this changes how far the paper plane flies. There is a lot of cool… Read more

Alternative energy sources are a big deal these days. One such source is the wind. Find out how a wind turbine can use the power of the wind to generate energy in this science fair engineering project. You'll design various blades to find out which produces the most energy, and put the wind to work for you! Read more

Have you ever wondered how a ship made of steel can float? If you drop a steel bolt in a bucket of water, the bolt quickly sinks to the bottom. Then how can a steel ship float? And better yet, how can a steel ship carry a heavy load without sinking? It has to do with the density, or the mass per volume, of the ship (and its cargo) compared to the density of water. In this science activity, you will make little "boats" out of aluminum foil to explore how their size affects how much weight… Read more

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 bag and a few strings is all it takes to make your figure into an expert skydiver. Read more

Have you ever wondered what makes a paper plane fly? Some paper planes clearly fly better than others. But why is this? One factor is the kind of design used to build the plane. In this activity, you will get to build a paper plane and change its basic design to see how this affects its flight. There is a lot of cool science in this activity, such as how forces act on a plane so it can fly, so get ready to start folding! Read more
