They will use a cup of ice water as a simple humidity detector. They will then examine how the humidity and temperature affect the environment.
This is an activity out of the book I have called Science Made Simple. Sample file contains a look at many lessons from the book so you can see the general quality of the lessons. All lessons are hands-on and use simple supplies that can be done by any teacher anywhere. The full book can be purchased in my store.
