Rain in a jar is one of the easiest science activities you can do with your kids. It’s suitable for at home or even a whole classroom full of children. With a few common materials, you can put this play idea together in under 5 minutes.

Weather science is a fun topic to teach kids. Even toddlers and preschoolers can understand it because they see it everyday. It affects how they dress, how they play and introduces them to some wonderful play-based learning.

Weather Science for Kids

One of my favorite science activities for kids is the Indoor Water Cycle Science Activity. With a few kitchen items you can turn saltwater into freshwater, making the water go through the whole water cycle in a way the kids can both see, and later taste.

If you’re heading into the rainy season be sure to learn How to make a Rain Gauge. This is one of the most simple weather activities for kids that is often overlooked.
