In this activity, learners work in teams to construct specific components of a model of the High Energy Solar Spectroscopic Imager (HESSI) spacecraft. Afterwards, the teams make presentations on the results of their effort. Note: HESSI is now named... (View More)

This resource provides illustrations showing how the coastline of California will change in response to the movement of the Earth's plates. Students assemble the illustrations to create an animated flip book. The resource is part of the teacher's... (View More)

In this activity, students create a model of sea floor spreading using two sheets of white paper and a metric ruler. The paper strips are pulled through a slit representing a mid-ocean ridge and divergent plate boundary. The model mimics how molten... (View More)

This Spanish web site explains why we need to study objects in space at many wavelengths. It includes a general overview of what we learn in each part of the spectrum and why we need to send telescopes into space.

Audience: Informal education

In this demonstration, an egg is used as a model of the Earth. The egg is tapped gently, to create cracks in the shell. The pieces of shell are analogous to the Earth's plates, and the cracks are used to explain plate boundaries. Using the egg, the... (View More)

In this activity, students use marks on a 1.4 m strip of paper to simulate light wave frequencies and measure the time it takes for different frequencies to pass through the "viewer" made from a manila folder. Students learn that different colors of... (View More)

This is an online lesson which introduces the concept of astronomical filters and their connections to imaging different objects in space. Learners will explore perceptions of images as seen using different colors of light, construct a filter wheel,... (View More)
