Looking for an easy science activity? Today I'm excited to share this sink or float free printable. It's fun one that is great for all ages. It can be a quick activity or if you're looking for something to keep them busy this summer, you can add lots of items to "test". There are 2 versions you can download and print for free. One has some suggested items to try out and one is blank. For the blank one you can have the kids gather a bunch of items they want to test out and write them down themselves. For little ones that can't write yet, have them draw the object.
