In this activity, students experiment to test the hypothesis that Mars was once hotter. The activity requires some advance preparation by the teacher: the day before the activity, need to place a plastic bottle filled with water in the freezer.... (View More)

Learners will consider the essential question, "How much energy does sunlight provide to the Earth and what is its role in the Earth’s energy resources?" Activities include building a device to measure the solar constant - the amount of energy in... (View More)

Audience: High school
Materials Cost: $1 - $5 per group of students

This is an activity about the Aurora Borealis or Northern Lights. Learners will plot the Auroral Oval in the northern hemisphere and determine the height of the northern lights using Carl Stormer's triangulation method. This activity corresponds to... (View More)

In this activity, students observe and sketch clouds, describing their forms. They will initially generate descriptions of a personal nature and then move toward building a more scientific vocabulary. They correlate their descriptions with the... (View More)

Students create a physical model illustrating soil water balance using drinking glasses to represent the soil column, and explain how the model can be used to interpret data and form predictions. Using data from the GLOBE Data Server, they calculate... (View More)

In this activity, a three-part questionnaire launches students into discussions about where objects in space are located, and when they formed - an introduction to the concepts of structure and evolution of the universe. By physically manipulating... (View More)

This article discusses how the Multi-angle Imaging SpectroRadiometer (MISR) instrument found on the Terra satellite is used to understand how particles in the atmosphere interact with sunlight and how particle pollution affects Earth's climate.... (View More)

This activity introduces measurement and scale using hands-on activities. In this activity, students use the concept of similar triangles to determine the height of a tree. This activity is one of several available on an educational poster related... (View More)

This is an activity about scale model building. Learners will use mathematics to determine the scale model size, construct a pattern, and build a one-fourth size scale model of the IMAGE (Imager for Magnetopause-to-Aurora Global Exploration)... (View More)

This inquiry activity supports student understanding of the cause of light, heat and shadow, how to measure the passage of time, and how to use rules and other measuring tools. Students make observations using shadows, a meter stick, and a homemade... (View More)
