Science fair project ideas for 2nd grade 4. **Density Tower**: This project is an excellent way to learn about density and how different materials interact with each other. You will need a few different liquids with different densities, such as water, oil, and corn syrup. Layer the liquids in a clear container and observe how the different liquids interact with each other. 5. **DIY Rainbow**: This project is an excellent way to learn about the properties of light and how it interacts with different materials. You will need a flashlight, a prism, and a few other household items. Shine the flashlight through the prism and observe how it separates the light into different colors. 6. **Elephant Toothpaste**: This project is an excellent way to learn about chemical reactions and how they can produce gas. You will need hydrogen peroxide, yeast, dish soap, and a few other household items. Mix the ingredients together and observe how the reaction produces a foamy substance that looks like elephant toothpaste. 7. **Ocean in a Bottle**: This project is an excellent way to learn about ocean currents and how they work. You will need a clear plastic bottle, water, food coloring, and a few other household items. Fill the bottle with water and add food coloring to create a realistic ocean scene. Then, add a small amount of cooking oil to simulate ocean currents. 8. **DIY Thermometer**: This project is an excellent way to learn about temperature and how it affects different materials. You will need a glass thermometer, rubbing alcohol, a small plastic bottle, and a few other household items. Fill the bottle with rubbing alcohol and add a few drops of food coloring.
