Science Fair Project Idea

Scientific Method

Imagine telling your friends about your latest science project: using a battery to make a light turn on. You might get some blank stares...sounds a little boring and basic, right? Now tell them you will do it with a potato! Yes, you can actually use fruits and vegetables as part of an electric power source! Batteries power many things around you, including cell phones, wireless video game controllers, and smoke detectors. In this science project, you will learn about the basics of battery… Read more

Have you ever heard that plastic can be made out of milk? If this sounds like something made-up to you, you may be surprised to learn that from the early 1900s until about 1945, milk was commonly used to make many different plastic ornaments, including buttons, decorative buckles, beads and other jewelry, fountain pens, the backings for hand-held mirrors, and fancy comb and brush sets. Milk plastic (usually called casein plastic) was even used to make jewelry for Queen Mary of England! In… Read more

Build a Simple Electric Motor!

Science Fair Project Idea

Scientific Method

When you think of a motor, you may immediately think of a car, but you actually encounter other motors in your home every day. That's right, if you put on clean clothes from the washing machine, ate food from the fridge, or used a fan, you used an electric motor. In this electronics science project, you will make a simple electric motor with two magnets that "talk" to each other. As they interact, they will alternate between "liking" each other (pulling together), and "disliking" each other… Read more

Make the Wind Work for You!

Science Fair Project Idea

Scientific Method

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

Make Popping Boba Balls Out of Your Drinks

Science Fair Project Idea

Scientific Method

Forget drinking your juice. Instead, try snacking on it! Use the steps and recipes in this food science project to transform drinks into semi-solid balls that pop in your mouth. The technique is called spherification and it is part of a larger food science trend called molecular gastronomy— but we just call it yummy science! Read more
