Seventh grade science fair projects provide students the chance to apply STEM (science, technology, engineering and math) concepts. Students may either follow a project as written or modify it to add their own unique twist.
Learn the secret behind glow-in-the-dark sticks, determine how far apart planets are, or uncover unexpected chemical reactions with these fun experiments!
Biofilm
Biofilms are communities of microorganisms such as bacteria that adhere and grow on surfaces. When left to their own devices, these microbes produce a slimy adhesive substance that encases them, making it hard for individual bacteria to leave or enter other surfaces; making treatment with antibiotics difficult in these communities.
Students can explore microbial biofilms through home science tools’ kits for growing bacterial colonies. Our easy bacterial growth kits feature everything necessary for starting their experiment, including an ultrasonic device which detaches cells 10 times more effectively than traditional swabbing.
Caffeine
An effective science fair project should capture students’ interest while remaining easy for them to comprehend. Experiments requiring complex equipment or human subjects often fall outside the scope of a 7th grade science fair project.
Try this chemistry experiment that involves using a simple chemical reaction to make ice cubes! It’s an enjoyable way to discover an everyday kitchen ingredient and makes for an awesome party favor!
Engineering novices love this engaging physics experiment that challenges them to determine how far a balloon car will travel while also imparting lessons about energy and momentum.
Plants
Students can gain insight into plants and their environment with a plant growth experiment. Children will grow plants using water from different sources–rainwater, tap water, salt water and soda water–and see how each affects its development.
Encourage children to discover more of the world with these exciting projects designed for seventh graders, helping them learn about the greenhouse effect, pond protozoa and more.
Make learning lab work and the basics of chemistry accessible to children by setting up this simple laboratory experiment with dry ice, taking note to follow all necessary safety procedures. Or help them engineer a hydraulic lift using whatever supplies may be lying around the house.
Pets
Students often form strong attachments to their pets, making science fair projects that involve animals an excellent way for them to explore scientific questions. Just remember that most schools or science fairs require any animal experiments be conducted safely so as not to compromise animal health or increase injury risks.
Students can test how certain soil types impact plant growth. They could also look at whether spherification – an engineering process that transforms liquid into solid balls – is an effective food preservation technique or use Newton’s Cradle to learn about centripetal force.
Cellular Mitosis
Cellular mitosis is an integral component of cell division, creating two identical cells with separate nuclei that allow reproduction and growth. The process is controlled through various checkpoints including prophase, prometaphase, metaphase, anaphase and telophase.
Kids will gain a better understanding of biology, chemistry and physics through hands-on experiments. They’ll discover why oil floats on water with this fun density experiment; or take on Linnaeus’ role with this simple system of taxonomy project!
Squirrels can be an annoyance in any backyard birder’s environment, but kids can help find effective strategies to deter them with this science fair experiment.
Hand
Science fair participation allows students to develop into independent researchers by selecting an intriguing topic, creating a testable hypothesis and conducting hands-on experiments. Participants also practice applying the scientific method used by professional scientists around the globe.
This engaging and easy experiment will show kids how to build a bridge inspired by Leonardo da Vinci’s 500-year-old self-supporting design from 1490. They can explore gravity as well as physics and engineering through testing different materials to see how much weight their bridge can support.
Bridge
From performing basic germ tests on household items to designing their own electroplating lab, seventh graders are ready to learn how to apply basic scientific principles to real-world tasks. From making cake or candy an experiment subject, or exploring Newton’s Cradle as a demonstration tool of how air molecules affect objects moving through space – seventh graders are ready to put science principles into action!
Students participating in this bridge project will construct various craft bridges from various materials and then test how well each one stands up under certain weight loads. At each test session, students will make observations and write down any hypotheses they come up with during this process.
