All About Solids, Liquids, and Gases
DVD 23 minutes + teachers guide
Presents an introduction to the three states of matter, including solids, liquids and gases, and provides information on their characteristics, nature, and behavior, looking at how each one can change into another, and discussing key concepts such as melting point, freezing point, and boiling point.
Adventures of Little Drip
1 VHS videocassette 15 minutes.
Explores the water cycle. Story of Little Drip, an animated character who fell off his "water cycle."
Water Cycle Simulator
1 model, 19" x 14 1/2" x 4" + guide
Create a water cycle as it occurs in nature. This experimental model creates a continuous water cycle that demonstrates precipitation, collection, evaporation, and condensation. It also graphically illustrates the distillation of water as it changes into gas. All processes are confined within the closed box; the sources of heat and cold are applied to the outside of the box. Model measures 19" x 14 1/2" x 4" and includes a study guide.
All About the Water Cycle
1 DVD, 23 minutes.
Describes the stages of the water cycle, visits an underground cavern examining water's role in creating these natural wonders, and shows how scientists are protecting the Earth's water supply. Discussion questions and activities -- Downloadable teacher's guide and investigation data sheet. Earth Science for Children series.
1 VHS videocassette, 14 minutes
