This is a lesson about using the light from the star during an occultation event to identify the atmosphere of a planet. Learners will add and subtract light curves (presented as a series of geometrical shapes) to understand how this could occur.... (View More)

Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. The... (View More)

This is a lesson about detecting ice on the permanently shadowed craters of Mercury and the Moon. Learners will consider what might be in that ice and will examine why the polar regions of Earth, Mercury and the Moon are colder than elsewhere on the... (View More)

In this activity, students engage in an ongoing investigation to find patterns of sunlight and shadow in a classroom (or any room that gets sunlight) at different times of the day and different times of the year. Students look for repeating... (View More)

Students will work in teams to create visual models to assist in understanding the volume of surface ozone in the air. Students construct cubes of different volumes and compare them to get a feel for parts per million by volume and parts per billion... (View More)

In this activity, students learn the basics of the horizon, direction and the rising and settings of the Sun and stars by making a schoolyard "medicine wheel" with sidewalk chalk on playground asphalt. Medicine wheels are stone rings constructed by... (View More)

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)

This is an activity about satellite size. Learners will calculate the volume of the IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) satellite, the first satellite mission to image the Earth's magnetosphere. They will then determine the... (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 paper scale model of the IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) satellite, the... (View More)
