Seventh Grade Science Projects (668 results)
Science Buddies' seventh grade science projects are the perfect way for seventh grade students to have fun exploring science, technology, engineering, and math (STEM). Our seventh grade projects are written and tested by scientists and are specifically created for use by students in the seventh grade. 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, seventh graders 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.
Let us help you find a science project that fits your interests, with our Topic Selection Wizard.

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…
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!
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.
Try your hand at this engineering challenge. Can you build a "launcher" device to launch a ball as far as possible and a "receiver" to catch it? Building a receiver provides an extra twist to a traditional catapult project. Add to the challenge by using a limited set of materials to build your machine and calculate a score based on your throw distance and materials used.
Do you filter your tap water before drinking? Many commercials claim these filters make your drinking water cleaner and safer. But what, exactly, are these filters doing and is the water really cleaner afterwards? The cleaning power comes from their filling material, called activated carbon. It exists in all kind of forms: powder, granules, foams, and blocks. Do you think it matters what type of activated carbon is inside the filter? In this activity you will investigate whether larger or…
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…
In this engineering challenge, you will build a device that can pick up a ping pong ball from a distance and return it to a start line. The farther away the ball is, and the fewer materials you use to build your device, the higher your score. Enter your score in the 2023 Science Buddies Engineering Challenge for a chance to win prizes! Teachers,
lesson plan versions of this challenge are also available.
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…
Some objects float on top of the ocean, and other objects sink to the bottom. Why? Try this eggsperiment to find out!
Do you want to trick friends and visitors with an amazing optical illusion? In this engineering design project you will learn how to build an infinity mirror,with built-in lights that make the mirror look like a deep tunnel with no end. But pick the mirror up and look behind it, and you will see that it is only a couple of inches thick! Read this project to find out not only how this illusion works, but how to design and build your very own infinity mirror from scratch.
