Students study weather in all its stillness and fury. They examine and use thermometers and find out why a change in temperature might also mean a change in clothes. Teachers share their ideas for hands-on activities, including encouraging students to walk in the rain to better understand the force of a downpour, or collecting snowflakes so they can see for themselves that each one really is different. Children learn about wind by blowing and following bubbles, and about light and shadow by playing with a lamp and a screen. A virtual treasure chest of early scientific childhood development and learning.
