![]() ![]() This simple but effective DIY science project teaches kids about air pressure and meteorology. (Bonus: Have students try different toothpaste and toothbrush combinations to see how effective they are.) In this experiment, students use eggs to determine how soda and juice stain the teeth and wear down the enamel. The calcium content of eggshells makes them a great stand-in for teeth.

Design your own slimeĬhances are good your students already love making and playing with slime. ![]() The supplies are simple, but the results are pretty neat! You’ll blow your seventh grade science students’ minds when you tell them they’re going to build a clock using engineering that’s been around for thousands of years. Learn more: Science Buddies/Mummified Hot Dog 13. Mummify a hot dogĪre your students fascinated by ancient Egypt? Then we’ve got the perfect seventh grade science project for your class! No need for canopic jars just grab some baking soda and get started. Learning about wave action? Build this surprisingly easy wave machine for hands-on exploration. Plenty of homes use water filtration systems these days, but how do they really work? This chemistry experiment explores how charcoal filters impurities from drinking water. Introduce the concept now with LEGO bricks. ![]() Discover computer coding with LEGO bricksĬhances are good at least some of the kids in your class will go on to work with computer code someday. We learn early on that oil floats on water, but where do other liquids fit in? Students find out when they conduct this colorful density experiment that has them layer different substances, making a rainbow. Learn more: Teaching Science With Lynda 8. Then, urge them to explore data collected by other scientists so they can learn to make informed decisions about topics like global warming. Watch the greenhouse effect in actionĬlimate change can be a contentious topic, so start by teaching kids about the greenhouse effect, which is easy to see and understand. Learn more: Science Buddies/Robotic Hand 7. This is a great individual or group seventh grade science project, as it encourages students to use and hone their design and engineering skills to make a working model of a hand. Learn more: Science Buddies/Newspaper Dome 6. This experiment requires nothing more than newspaper and masking tape! Construct a geodesic domeīudding engineers will love designing, building, and testing the strength of the fascinating geodesic dome. Learn more: Steve Spangler Science/Can Crusher 5. Sure, it’s easy to crush a soda can with your bare hands, but what if you could do it without touching it at all? That’s the power of air pressure! They’ll need some supervision with the fire, so try this out on the playground for extra safety. This easy experiment is a cool way to show kids how heat affects air molecules, making hot air rise. The only special supply you need is a plug-in light socket. When you build your own grow box, there are lots of seventh grade science fair projects you can do with it. ![]() Experiment to see how far or fast you can make the car go. Drive a balloon-powered carĮngineer a balloon-powered car using basic materials from around the house (even the wheels are bottle caps!). This huge list of seventh grade science ideas covers biology, chemistry, physics, and more. Whether you’re prepping for a middle school science fair or looking for ways to make classroom lessons more exciting, hands-on activities are the answer. Did you know you can use cabbage to test pH? ![]()
