Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

Students role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...

Students examine the phases of the water cycle and water's different forms it can have. They work in groups to create pantomimes to illustrate the water cycle to their classmates.

Students explore Earth's seasons using an interactive website. In this earth science activity, students watch video segments and explain Earth's seasonal milestones. They discuss the factors that causes seasonal changes.
