- Build a Volcano: Create a model volcano using baking soda and vinegar to simulate an erupting volcano.
- Investigate Solar Energy: Build a solar-powered cooker and demonstrate how it can be used to cook food using only the power of the sun.
- Study Aerodynamics: Design and build a paper airplane that can fly the farthest distance or stay in the air the longest.
- Explore Magnetism: Investigate the properties of magnets and conduct experiments to see how they attract or repel various objects.
- Experiment with Density: Explore the concept of density by creating different saltwater solutions and observing how objects float or sink.
- Test the Power of Lemon Batteries: Use lemons to create a simple battery and investigate how different fruits or vegetables can generate electricity.
- Investigate Plant Growth: Design an experiment to determine the effects of various factors, such as light, water, or temperature, on the growth of plants.
- Study the Water Cycle: Create a mini water cycle model to understand the processes of evaporation, condensation, and precipitation.
- Build a Simple Circuit: Learn about electricity by building a basic circuit using batteries, wires, and a light bulb.
- Investigate Sound Waves: Conduct experiments to explore how sound travels through different mediums, such as air, water, or solids.
- Explore Chemical Reactions: Perform simple chemical reactions, such as mixing baking soda and vinegar, to observe the formation of gas and other changes.
- Investigate Static Electricity: Generate static electricity and observe its effects on objects, such as attracting or repelling lightweight particles.
- Study the Effects of Acid Rain: Create an experiment to understand the impact of acid rain on plants, metals, or other materials.
- Experiment with Insulation: Test different materials to determine which ones are the best insulators and can effectively prevent heat transfer.
- Investigate Reflection and Refraction: Explore how light behaves when it encounters different surfaces, such as mirrors or lenses, through experiments and observations.
These science projects and experiments provide hands-on learning opportunities for 7th graders to explore various scientific concepts while having fun. Remember to always follow safety guidelines and seek guidance from a teacher or adult when conducting experiments.
