Fun science experiments to explore everything from kitchen chemistry to DIY mini drones. Easy to set up and perfect for home or school. Browse the collection and see what you want to try first!
Science Buddies' middle school science projects are the perfect way for middle school students to have fun exploring science, technology, engineering, and math (STEM). Our middle school projects are written and tested by scientists and are specifically created for use by students in the middle school grades. Students can choose to follow the science experiment as written or put their own spin on the project.
For a personalized list of science projects, middle schoolers can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

What Makes Ice Melt Fastest? Log in to add favorite More Menu
Science Fair Project Idea If you live in a place that gets cold in the winter, you have probably seen trucks out spreading a mixture of sand and salt on the streets after a snowfall to help de-ice the road. Have you ever wondered how this works? This basic chemistry project can give you some clues. Read more
Make Ice Cream in a Bag Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 509 reviews Have you ever made ice cream? It can be a lot of fun, and you end up with a tasty frozen treat! There is actually a lot of interesting chemistry that goes on behind making ice cream. For example, think about how you start out with refrigerated (or room-temperature) ingredients and then need to cool them down to turn them turn into ice cream. How do the ingredients change during this process? How important do you think it is that they are cooled to a certain temperature? In this science… Read more
Balloon-Powered Car Challenge Log in to add favorite More Menu
Science Fair Project Idea Do you think you could build a car powered by nothing but air? A balloon-powered car is pushed forward by air escaping from a balloon, and it is fun and easy to build with materials you already have around your house. Can you imagine how you would want your own balloon-powered car to look? Can you design a car that will travel as far as possible? You can even measure your car's speed using your smartphone and a special sensor app. Get ready to grab some simple supplies to bring your idea to… Read more
Build a Floating Maglev Train Log in to add favorite More Menu
Science Fair Project Idea How can you make a train without wheels? By using magnets! In this project you will build a magnetic levitation ("maglev" for short) train that floats above a magnetic track. How much weight can you add to the train before it sinks down and touches the track? Read more

Build a Simple Electric Motor! Log in to add favorite More Menu
Science Fair Project Idea 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

STEM Activity 1 2 3 4 5 251 reviews Create a giant foaming reaction and wow your friends with this classic science demonstration! With just a few simple ingredients, you can make something that looks like toothpaste being squeezed from a tube—but so big, it must be for elephants! Read more
Does Color Affect Taste? Log in to add favorite More Menu
Science Fair Project Idea You might have heard the saying "The eyes eat before the mouth." The appearance of food, especially its color, certainly affects how we perceive its taste. But can your eyes actually change the way you taste something? In this science project, you will find out by investigating how people perceive the taste of different colored apple juice. How do you think color affects taste? Read more
