Focusing on air, water, land and life, this video describes how these components are connected in the Earth system through the flow of energy, cycles of water and biogeochemistry. Methods of studying the Earth system, ranging from field observations... (View More)

This video demonstrates students measuring the transparency of water, a measure of water quality, using a Secchi disk or turbidity tube. Field measurements of water temperature are also shown. The resource includes a video and a written transcript,... (View More)

In this demonstration, relative humidity is modeled using a sponge and a pan of water, and the concept of saturation is depicted. Students answer questions examining the relationship between temperature and the capacity of air to hold water vapor.... (View More)

This is a short activity about our Sun. Learners will read a page of information about our Sun and the electromagnetic spectrum and answer questions in an accompanying worksheet. This activity is from the Stanford Solar Center's All About the Sun:... (View More)

This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept. The resource is from PUMAS -... (View More)

In this activity, students learn that the small droplet size of water the in the clouds and wind contribute to clouds remaining suspended in the sky. The demonstration requires a clear beaker, sand, and rocks. Several other activities are suggested.... (View More)

This math example explains what celestial objects a person can see with the unaided eye from the vantage points of Earth and Mars, using simple math, algebra and astronomical distance information. This resource is from PUMAS - Practical Uses of Math... (View More)
