In this activity, students will learn how technology can help scientists solve a problem. One of the challenges scientists face with any spacecraft is attitude control. Students will be introduced to the problem of attitude control in space through... (View More)

This exploration engages students in an investigation that leads them to the conclusion that regions of the electromagnetic spectrum vary according to energy per photon, and connects with the video where Dr. Ilana Harrus explains observing a... (View More)

Audience: High school

This activity models grazing incidence reflection by using students as the “sea of electrons” provided generally by metallic bonding on the surface of a metal. A tossed ball is used to represent a photon of light and the ball tosser represents... (View More)

This is a lesson about water and water-ice. Learners will explore the molecular geometry and mechanics of ice. They will create a model of H2O, investigate its molecular structure and its consistent shape. Faraday's experiment is used as background.... (View More)

This is a lesson about condensation, snow and snowflakes. Learners will investigate how water and ice exist in the atmosphere as they study water vapor condensing, find that clouds are made of tiny droplets of water, and notice that snow forms in... (View More)

This is a lesson about the characteristics of ice as a mineral and how it compares to other minerals with respect to hardness. Learners will observe ice crystals, develop a hardness scale and position ice on it. Learners will also practice working... (View More)

This is a lesson about how and why ice flows, especially in a large mass such as a glacier. Learners will experience the qualities of viscoelastic materials and view videos of glacial ice flows. They will observe ice flows and materials other than... (View More)

This is an activity about vectors and velocity. It outlines the addition and subtraction of vectors, and introduces the application of trigonometry to describing vectors. The resource is designed to support student analysis of THEMIS (Time History... (View More)

In this activity, students use a piano keyboard to model spectral lines as musical chords. It is designed to aid student understanding of spectral analysis, what the patterns mean, how elements are involved, and how this relates to stars.... (View More)

This is a lesson to demonstrate magnetic field lines in 2- and 3-dimensions. In the first activity, learners sprinkle iron filings over a magnet underneath a paper and record their observations. The second activity involves building a 3-D magnetic... (View More)
