This demonstration allows students to visualize how heat moves through convection - using water, food coloring, a small cup and a large jar - and prompts them to make a connection between the observed process and cloud formation. The resource is... (View More)

This is a lesson about elemental abundance in solar wind. Learners will simulate the extraction of elements from the Genesis wafers by counting elements extracted from a simulated sample. This will help them learn how the Genesis samples help... (View More)

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

This is an activity about light and its component colors. Learners will observe a photograph of a rainbow and make observations about what they see in the photo. Next, they will observe a rainbow spectrum and draw the rainbow using crayons. Finally,... (View More)

Audience: Elementary school

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)

In the culminating activity of this investigation, students write an editorial entitled, Are We Warming Earth?, in which they attempt to persuade readers to take global warming seriously. Leading up to that activity, students read background... (View More)

El Niño Southern Oscillation (ENSO) affects weather, climate, and, consequently, humans and their activities. In this investigation, students review and analyze ENSO background info, data and satellite images in preparation for a game. Acting as... (View More)

This activity introduces the primary colors of light. Satellites transmit images to us as a series of numbers, and this activity is designed to show how numbers are combined to create images using the primary colors of light. Students work in groups... (View More)

Students identify the actual colors of objects bathed in monochromatic light and learn how three colors of light can be combined to produce colors ranging from black to white. Students see how space observatories make use of monochromatic filters to... (View More)

Students determine the ability of various lenses and mirrors to gather light in order to compare and calculate their light gathering power. This activity is part of Unit 3 in the Space Based Astronomy guide that contains background information,... (View More)

This is an activity about the differences in thermal behavior between similar materials having different physical properties. Learners will measure temperature of two different surfaces; sand and stone; on a sunny day, make a series of temperature... (View More)
