Science fair project ideas for 2nd grade 3. **Plant Germination Experiment**: This project is an excellent way to learn about the life cycle of plants and how they grow. You will need a few different types of seeds, some potting soil, and a few small pots. Plant the seeds and observe how they grow over time. You can compare the growth rates of different types of seeds or explore how different conditions affect plant growth. 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. Then, attach the thermometer to the bottle and observe how the temperature affects the level of the alcohol. 1. **Use the Papa John's website or app:** The easiest way to find the nearest Papa John's is to use the store locator feature on the company's website or mobile app. Simply visit or open the Papa John's app, enter your address or zip code, and the locator will show you the nearest Papa John's locations. You can also filter the results by services offered, such as delivery, carryout, or dine-in. 3. **Plant Germination Experiment**: This project is an excellent way to learn about the life cycle of plants and how they grow.

You will need a lemon, a copper penny, a zinc-coated nail, and a few other household items. Insert the penny and nail into the lemon and connect them with a wire to create a simple battery. 10. **DIY Parachute**: This project is an excellent way to learn about air resistance and how it affects different objects. You will need a small toy figure, a plastic bag, some string, and a few other household items. Attach the string to the toy figure and the plastic bag to create a simple parachute. Then, drop the toy figure from a height and observe how the parachute slows its descent. These science fair project ideas for 2nd grade are just a starting point. Encourage your child to explore their interests and come up with their own project ideas. With a little creativity and some basic materials, your child can have a fun and educational science fair experience.
