Young children enjoy learning about how things work.

By participating in a vast array of science activities, they are learning important critical thinking and observation skills.

These activities also promote their inherent sense of curiosity about the world.

For this activity we experimented with sinking and floating.

Using real items (in our case crustaceans and sea shells), we placed them in fresh water and then salt water (to incorporate into our Under the Sea theme) and observed whether they would sink or float.
