Get Your Techno On
Desert regions are hotter for multiple reasons; the lack of vegetation causes the sun's heat to go straight into the surface and the lack of moisture means none of the heat is being transferred into evaporation. This concept, and other...

The Cycle of Water
Help young scientists get to the bottom of the water cycle with this comprehensive earth science lesson. After first viewing and discussing presentations about the states of water and the water cycle, the class performs a series of...

Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...
Science 4 Inquiry
States and Phases of Matter
Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

Splish! Splash! From the Bath to my Glass
An excellent instructional activity on the water cycle! In it, learners should gain a general understanding of the water cycle, along with how water first falls as precipitation, then ends up coming out of our faucets. This instructional...

Condensation
It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...
