Sink or Float Science Exploration

Which objects sink and which objects float? This science exploration is a great way for preschoolers to learn how our world works. Just gather materials (all objects you can find around your home/classroom) and test whether objects sink or float.

Add these cards as a visual sort in your science center. Each card comes with a picture and a word for students to easily sort on their own. Perfect water science activity for your ocean theme or anytime!
