Doing science projects during class is a great way to get your students interested in class. But how do you continue these projects outside of the classroom? Here is a list of the top 25 2nd grade science projects to keep your students learning, even when they’re not in class. And best of all, they’ll have fun!

1. The Amazing Growing Gummy Bear

This project focuses on the scientific method and requires little more than common household items, since this experiment is essentially a mixture of candy in liquid. However, we don’t recommend eating this, as it’s not an edible science experiment!

2. Make a Model Steam Engine

This is a fun project that I use to help my students understand temperature for earth science. It can also serve to teach the water cycle and requires only a few items, such as pipe cleaners and a plastic bottle.

3. Dig up bones!

Get your students out of the house with this classic experiment. Students will  compare bones that they dig up and record differences in the bones found. You can also use this to teach about different rocks and rock layers.

4. Learn how leaves get water

This is a great example of experiments for kids to teach about plant adaptations and the cycle of plants. Choosing any outdoor plant with leaves and keep water level records in a science journal.

5. Jumping Goop

Use this experiment to teach second grade concepts, like friction and states of matter with just a few household items.

6. Kool-aid Rock Candy

No, not that kind of rock candy! This colorful experiment is also a great idea for a science fair project by making new candy through mixing colors and a variety of liquids.
