Science fair projects enable children to explore scientific concepts through hands-on experiences. Students can discover solar systems, glow-in-the-dark plants and unexpected chemical reactions using these innovative ideas.
Conduct a model experiment to test how oil floats on water or follow in Linnaeus’ footsteps and develop your own system of plant taxonomy. Students can also get hands-on experience through this exciting rusting experiment or try this quick yet efficient insulation test.
Solar Oven
Use solar energy to craft tasty treats with this straightforward science project! Kids create a pizza box solar oven that absorbs light through foil-lined flaps, plastic windows and black paper; then it retains heat by acting like insulation – perfect for cooking food inside. In addition, this activity teaches kids about absorption and insulation!
This seventh grade science fair project can be done in groups or pairs and easily monitored by parents.
Spherification
Engineers-in-the-making will have loads of fun designing, building, and testing the strength of this fascinating geodesic dome.
This simple experiment will show children how heat affects air molecules, leading them to move upwards, creating hot air pockets. Please supervise any use of fire!
Use this fun experiment to explore spherification, the process of turning liquid into gel-like spheres that can then be used to produce culinary treats like boba tea.
Egg Float
Discover how gravity impacts an egg’s weight with this straightforward experiment, designed to show children about centripetal force.
Submerge an egg in fresh water before slowly adding salt. Watch as it sinks to the bottom when fresh water is added; but once more salt has been added, it floats on top! Use this experiment to understand density (which measures mass per volume of liquid). Also a great way to teach children about mixtures.
Hand Model
Students can apply their design and engineering abilities to build an in-depth model of the human hand, using design principles to explore its musculoskeletal structure, finger size variation among different digits and more.
Use this simple experiment to explore how gravity alters the shape of objects using gravity as a force, helping children understand concepts like centripetal force.
Climate Change
Explore the science of weather using a barometer and cloud types with this EPA resource designed specifically for seventh graders. Experimentations are provided.
Show how our atmosphere warms the Earth using this simple experiment from Steve Spangler Science. Students can also create balloon-powered cars to gain knowledge about air pressure.
Rainbow Density
The Rainbow Density project introduces kids to density through sensory exploration. Additionally, this activity introduces layers, color theory and mathematics.
Students will discover that liquids of differing densities float and stack separately upon one another – making this an exciting spring science experiment suitable for preschool, pre-k, kindergarten, grade 1, 2, 3, 4 and 5 students alike!
Stretch Test
Discover how important stretching truly is by comparing the flexibility of willing test subjects before and after stretch exercises using this exciting seventh grade science project.
Prep time may take longer, but kids will truly feel like scientists when extracting onion DNA using this easy experiment. Plus, it provides them with valuable lessons about scientific procedures!
Bacteria
Bacteria are everywhere and this fun experiment will demonstrate just how quickly bacteria can grow when placed in a petri dish with nutrient agar. Try sampling surfaces such as toilet seats, door handles and faucets to see which harbor the highest number of microorganisms.
Unwrap the potential impact of stress on your body temperature by comparing this volunteer’s results from Before to After. You might be amazed!
Biofilm
Biofilms are slimy layers formed by bacteria growing on objects in watery environments that cover surfaces, typically made up of one bacterial species or more likely a community of microbes such as bacteria, fungi, algae and protozoa.
Biofilms make nutrient exchange simpler than free-floating cells, leading to the evolution of more adapted strains of bacteria and the more rapid transfer of genetic material between cells.
Slime
Slime making is an engaging science fair project for kids of all ages, making a perfect way to channel that enthusiasm into something tangible. These experiments allow your young scientist to experiment with various ingredients and properties ranging from magnetic mud to glow-in-the-dark slime!
Select an ingredient and alter it, taking careful note to see how this changes its consistency, stretchiness or gooeyness of your slime. Take notes, pictures or record video so you can evaluate and share your results later on.
