This science book came with our Timberdoodle prek kit And it is just so cute. There are 14 labs in it that are geared towards small children. The things I like best is that the last page has a great introduction to what a science lab would entail when your kids get older. From making a hypothesis to what happens during and after the experiment.
Most of the items needed for each experiment you might already have but if not your local grocery store will probably have them. You don’t need that many things for the labs and each one has amazing pictures so that if your child doesn’t read yet they are able to easily understand what needs to be done.
Our daughter’s favorite experiment is one that involves her sea animals toys. I froze them in water and then we use warm water to melt the ice. I love that the book also gives suggestions of other things you can do during the lab to see if there are different effects, like putting salt on the ice. I would definitely recommend Look I’m a Scientist to get your littles excited about science.
