Science fair projects provide students with an engaging opportunity to study biology, chemistry, physics and other STEM disciplines. With creative 7th grade science fair ideas that allow for experimentation, innovation and study that keeps their attention, science fair projects can help students learn all they need about these sciences – making for a truly enjoyable science experience!
Does caffeine boost typing speed? Put that theory to the test with this straightforward experiment!
Pinball Machine
Engage students in this hands-on experiment that shows them how a solenoid works, while exploring physics and sound waves simultaneously.
Kids can use this science fair project to explore oxidation and corrosion through this simple chemistry experiment, making a fascinating science fair project out of learning how everyday actions affect the environment.
Swab household items to discover what germs live on them with this popular science fair project for 7th graders interested in bacteriology. It makes an ideal project.
Helicopter Car
Students explore aerodynamics and the creation of lift by wings with this easy-to-build helicopter. The shape of the paper cutout determines how much rubber band energy goes to powering its propeller.
Dividing your class into teams, challenge them to predict and construct a helicopter which can safely descend from a specified height, before testing and recording results. This project showcases Newton’s law of motion: every action produces equal and opposite reactions.
Electric Generator
An electric generator is an excellent way to demonstrate how electricity is created. Students spin magnets and copper wire to generate power that lights bulbs.
Does caffeine enhance productivity? Test this theory in this 7th grade science experiment! This project encourages students to record data and track results over time.
Pet Feeder
7th graders explore engineering and physics with these engaging projects, from balloon-powered cars to solar ovens! Engineering one will help students explore centripetal force; creating one will allow for reflection, convection and thermal energy analysis to learn more effectively.
Make slime with glow-in-the-dark ingredients for an interactive chemistry experiment, explore water filtration with this easy experiment, or follow in Darwin’s footsteps and observe finch beak adaptations with Project FeederWatch lab!
Cellular Mitosis Models
Students gain insight into mitosis using a model they build themselves. After receiving instruction on mitosis, they use a circle of textured paper or material and toothpicks to construct a model of cell division.
Explore the strength of various natural fibers with this engaging science fair project, providing an engaging way for teaching about materials and their physical properties.
Soak eggshells in various liquids to demonstrate how acids and sugar affect teeth. This experiment is suitable for 7th grade science studies.
Friction Experiment
Explore force and motion through this engaging friction science experiment! Kids can observe how much strength it takes to drag a book across various surfaces.
Try interlacing two stacks of books together and then pulling them apart – you will notice they stick like glue due to frictional forces created between their surfaces – rough surfaces have more frictional force than smooth ones!
Natural Fiber Experiment
Students can demonstrate how natural fibers found in spider silk or seaweed can be utilized to make eco-friendly textiles, creating an engaging experiment which blends engineering, biology, and chemistry together.
This project adds a twist to the classic egg drop experiment by teaching eighth graders that almost anything with a center of gravity can be balanced.
Red Cabbage Chemistry Experiment
Red cabbage contains anthocyanin pigments that act as natural acid-base indicators; when mixed with acids it turns redder while greener when combined with bases.
Place eight paper cups filled with different acids or bases (such as milk, Windex, soda pop and baking soda) into which different acids or bases will be introduced, such as milk. Pour a small amount of cabbage indicator in each cup and observe its effect on color change.
Copper-Plated Coins
New pennies may appear bright and shiny at first, but over time their brightness begins to dim. Try this experiment to learn why this occurs.
Use electricity to copper-plate a brass key, using alligator clips to secure its copper electrode to the positive terminal (anode) and brass key (cathode). Weigh both before and after coating to determine how much copper was applied.
Balloon Experiment
Students build and test a Rube Goldberg machine to explore mechanical engineering and physics. This experiment shows how air expands when heated, providing an engaging demonstration of thermodynamics.
Does caffeine boost productivity? This science fair project helps children explore chemistry and its effects, including caffeine’s relationship to strength testing of different natural fibers; they gain invaluable knowledge of material science and engineering as part of this experiment.
