This simple but effective DIY science project teaches kids about air pressure and meteorology. Learn more: Science Buddies/Onion DNA 23. Most of what you need you can find at home, and you can get 95% ethanol at Amazon. This experiment takes a bit of time and requires a few special supplies, but kids will truly feel like scientists when they extract onion DNA via a test tube. (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. Learn more: Science Buddies/Slime Varieties 21. Turn the fun into an experiment by changing the ingredients to create slime with a variety of properties, from magnetic to glow-in-the-dark! 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 19. 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. Find a terrific kid-friendly test tube set here. Simply boil some red cabbage and have students use the resulting water to test various substances-acids turn red, and bases turn green. Teach kids about acids and bases without needing PH test strips. Learn more: Science Buddies/Calories Experiment 15. Burn calories to explore stored energyĮver wonder how scientists determine how many calories are in your food? Try this experiment to find out! Learn more: Little Bins for Little Hands 14. Introduce the concept now with LEGO bricks.
#RAINBOW EXPO MARKERS CODE#
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. Learn more: ThoughtCo/Density Rainbow 13. 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 12. 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: Uplifting Mayhem/Salt Water Density 11. Learn how salt affects densityĮxplore the salinity of various bodies of water, then re-create their waters to see if you can make an egg float or sink. Learn more: Science Buddies/Robotic Hand 10. 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/Spherification 9. This is a cool chemistry experiment and tasty too! Spherification is a hot trend in top restaurants, but seventh grade science students can easily replicate it at home with a spherification kit. They can serve up their experiment results along with their final reports! Students experiment with the best way to build a solar oven, exploring thermal energy, reflection, convection, and other physics concepts. Learn more: Science Buddies/Newspaper Dome 7. 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 6. 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. When you’re finished, you can enjoy a sweet treat! If you’re learning about how genetic traits are passed along from parent to child, try this jelly-bean demo.
