What are some indoor kindergarten science activities?

Science Museums

Science museums are great places to learn about science. Children's museums, science museums, natural history museums, space museums, and discovery museums are all great places to do that! The museums usually have hands-on kindergarten science activities for kids to discover and explore science for themselves.

Look out for free admission days or free passes to a science museum near you! Check your credit card for offers, your local library for free museum passes, and local science museums for free entrance days.

Find a science museum near you and wow kids with the wonders of science! From my childhood to adulthood, I'm still in awe whenever I visit a science museum!
