Activities

One of the best ways to learn is to play. We have a collection of activities that let you learn biology by playing. You can try a biology experiment or test your knowledge with one of the biology puzzles based on our stories. There are printable and online coloring pages and worksheets that you can use to practice your coloring skills.

Wait, there's more. The Bird Finder tool can help you identify that mystery bird in your backyard. You can also venture into Body Depot where you can learn about your body and the biology that keeps it going. With so many activities you might find it hard to choose, so don't. You can try them all.
