Students love hands-on experiments, and these projects will give them a taste of being real scientists. From making their own classic vinegar and baking soda volcano to discovering how music affects plant growth, these experiments cover biology, chemistry and physics – perfect for keeping students busy learning while having fun!
Be a science hero this school year by engaging your students with this exciting project that teaches them to build their own batteries! Plus, they’ll gain insight into atmospheric pressure and its effect on objects!
Make Your Own Lip Balm
Find a science fair project idea that both engages their curiosity while pushing their knowledge is crucial for any student looking to submit an entry in this year’s science fair competition. Doing this will enable them to better connect with scientific concepts they are studying, making their presentations even more captivating for peers and judges.
Kids can explore oxidation with this rusty nail experiment, determine density of liquids using this vibrant experiment that layers different substances, or even create their own barometer. Other projects include testing how different materials keep hands warm, investigating fast food nutrition and demonstrating air pressure through this can crusher experiment.
Collect and Measure Biofilm
Students can explore biofilm using a simple kit composed of copper strips, batteries and 9V battery snap connectors with alligator clips. Students can test germ and bacterial growth using this classic science fair experiment. They could even take up Linnaeus’ role by creating their own system of taxonomy or testing whether music affects plant growth rates in this straightforward project.
Parents must help guide and support their child during experiments, but should allow him/her to run most of them on their own. Background research can be provided, while they let their child lead most of the experiment themselves.
Balloon Science
If your 7th grader is taking part in a science fair, help them choose a manageable experiment and guide them through testing process. Students will have to create both a board that displays results of experiment and packet that contains their work.
Encourage them to document their process by taking pictures and adding them to the board — this will add content and make their project easier to explain on presentation day. Make sure they have water or beverages available on that day, as well as keeping a repair kit handy in case anything needs fixing up during their experiment.
Texting Glossary
Seventh grade is a great time for science fairs, but students must be prepared to conduct their own experiments independently. Teachers and parents can help guide children with manageable experiments and appropriate work technology that make conducting projects simpler for children.
Create your own system for collecting bacterial biofilm with this ecology project or test the greenhouse effect with this simple climate change experiment.
Discover how oil and water behave as floating molecules by performing this simple yet captivating physics experiment. Other fun experiments involve exploring how far apart planets are, making glow-in-the-dark sticks, or witnessing unexpected chemical reactions.
Centripetal Force
Some science fair projects ask students to test a hypothesis, while others demonstrate or recreate known scientific principles. For instance, students might build Newton’s cradle to see how lighting a candle again affects its momentum or use easy-to-make magnetic slime for a simple chemistry experiment.
Discover centripetal force, or net force that causes objects to seek their center, via balloon tethers and satellite orbital mechanics. Centripetal force can be demonstrated through tension in balloon strings or gravity pull.
Acid Rain
Acid rain is one of the many impacts of air pollution on our atmosphere. Its source can range from humans (from burning fossil fuels) or natural sources (volcanic emissions), to combine with water vapor to produce acids that penetrate aquatic ecosystems and harm living organisms.
Students can mimic acid rain on aquatic environments by creating different concentrations of acidity using household vinegar. They should observe its impact on organisms in each experimental environment and compare results.
Plant Growth
Plant growth is an essential concept for students to grasp. Much like humans, plants undergo different stages of life that call for different nutrient requirements.
Typically, larger organisms are capable of gathering more material than their smaller counterparts; but what limits this process?
This low-tech experiment with leaf disks provides children with an easy way to observe photosynthesis in action. When combined with growing potatoes or cabbage clones in tubs or containers, students can observe how different environmental conditions influence plant life – making this project an invaluable addition to an ecology unit!
