Sweat Helps Me Cool Down
The Human Body
After playing, little drops may appear on the skin. As this sweat evaporates, it takes heat away. This is one way the body cools itself.
Did you know?
Sweat is mostly water with a little salt.

An idea to try
With an adult, observe a water drop on a surface. Return later and describe what changed.
For the adult reading along
A little more to discover
Evaporation, rather than the mere presence of drops, removes heat. Shade and drinking water are part of this ordinary break after playing.
