Water Investigations

Sink and Floating 
The goal of this experience is to explore the ways some materials float and sink. We made predictions of what objects would sink or float and why???
We tested many different objects.

Water Drop Races 
For this investigation, we explored the speed of movement of drops of water on a ramp.
Why do drops of water move down the ramp?
What would make the drops move down the ramp slower?
Do big drops move down the ramp faster or slower than the small drops/

Water's "Skin"
Exploring Surface Tension
In this experience the children explored the ability of water to hold together like a sheet. Our Voice Thread below will share some of the investigations we did!!
