Little kids are born scientists, which is why science experiments and activities are so much fun for them. From the time they are barely learning to crawl they are putting the scientific method in action.
They observe their world and make new discoveries each and every day. When they are babies they taste and touch pretty much everything as a means of learning about their environment. As they get a bit older they ask a million questions because they have a natural curiosity about life and how the world works.
This post is a list of over 70 fun science experiments and activities for kids to help encourage and enhance that natural curiosity that young children have for science. These experiments and activities are simply amazing and fun for kids of all ages!
These activities are brought to you by some of the most phenomenal kid bloggers out there. They are truly fantastic, so I encourage you to check out their blogs and I promise you will not be disappointed!
