7th grade science projects provide children an exciting way to explore their curiosity about the world. Experiments should challenge children, yet still allow for comprehension.
Explore this engaging physics experiment where students build their own Newton’s Cradle model and use it to learn about friction and gravity.
By the 7th grade, students are ready to expand their experimentation and explore how different branches of science (biology, chemistry, physics and environmental) interact. Plant-based projects provide an ideal way to do just that!
Discover if leaves have various hidden colors with this simple yet exciting hands-on plant science experiment, or test how music affects plant growth with another great hands-on experiment. Additionally, students can grow plants in soil-filled containers while studying how the environment impacts their health through this easy experiment.
Kids can even build their own plant-powered battery with this innovative project! Other great 7th grade science fair experiments for 7th graders include testing how fast food nutrition affects plants; studying greenhouse effects with this experiment; or discovering why oil floats on water with this colorful density experiment.
By seventh grade, students are often ready to tackle more intricate science fair experiments and are eager to understand how things work. Biology-centered projects such as these will allow them to use the scientific method while exploring their individual interests.
Doing a salt water experiment is an exciting chemistry experiment! Students fill three freezable plastic cups with water, adding two teaspoons of salt in one and only water in another before observing and recording results.
Clean drinking water is an invaluable commodity. Help your 7th graders explore ways to purify and recycle it with these easy physics experiments, including building solar-powered desalination machines. Additionally, this is a great opportunity for them to gain insights into greenhouse effects and other environmental issues.
Students gain insight into astronomy, geology and weather through these earth science fair projects. From classic experiments such as whether introverts have better memories to creating slime with magnetic properties or glow-in-the-dark properties with food-grade slime; kids can even build their own Rube Goldberg machines using just basic materials!
Kids will easily grasp the greenhouse effect with this engaging experiment! Later, students can utilize data compiled by scientists to explore climate change.
This balancing act experiment teaches kids about gravity with just a pencil and potato on the edge of a table. For an enhanced challenge, add Mentos diet pop to see how far the diet pop shoots! Students may also explore water filtration using simple ingredients found around their home and an old jar!
At this age, students are ready to explore more complex ideas in science. Our seventh grade science fair projects provide them with the perfect way to extend their academics beyond textbooks and classroom walls.
Conduct an experiment comparing vinegar vs commercial cleaning agents or observe how acid rain impacts the environment – this will encourage students to think critically about topics like climate change and pollution!
As an easy, accessible environmental science experiment, children could try keeping plants under various lighting conditions and monitoring their growth rates. They could also recreate real-world water problems like fertilizer runoff in a fish tank to see the effects it has on aquatic life within. Finally, let them experiment with spherification – the hot new trend among restaurants but which can also be done at home using basic ingredients – an excellent chemistry experiment that also teaches about density and surface tension.
