## Measuring Angular Size and Distance

This is an activity about measuring angular size and understanding the solar and lunar proportions that result in solar eclipses. Learners will use triangles and proportions to create a shoebox eclipse simulator.

## What Is There to See From Sea to Shining Sea?

This investigation teaches that physical and human features are used to characterize places on Earth.

## Sun and Space Weather: Presentation for Elementary School Teachers

This is a presentation about the Sun. Learners will hear about its cycles, as well as important features like solar flares, prominences, coronal mass ejections, and magnetic loops.

## SciJinks: Play Spectrix!

This game helps students understand how multiple remote sensing wave bands can be combined to reveal new information about the weather. SciJinks is a joint NASA/NOAA educational website targeting middle school-aged children and their educators.

## NuSTAR Educators Guide: Medical X-rays

Students read and analyze two different articles about medical imaging using X-rays. This activity is from the NuSTAR Educators Guide: X-Rays on Earth and from Space, which focuses on the science and engineering design of NASA's NuSTAR mission.

## NGC 3314: A Tale of Two Galaxies Lithograph and Classroom Activity

This Hubble Space Telescope image reveals two galaxies that look like they are slamming into each other, but they are actually separated by many millions of light-years. The system consists of a face-on spiral galaxy that lies in front of another larger spiral galaxy.

## Rational Number Operations

Students will learn about the twin STEREO spacecraft and how they are being used to track solar storms through reading a NASA press release and viewing a NASA eClips™ video segment.

## Principles in Remote Sensing: Earth Observations from Satellites

In this self-paced, interactive tutorial, learners become familiar with basic concepts related to remote sensing of the Earth by satellites.

## MRC: Landing, Moving, and Surviving Conditions (Grades 6-8)

This lesson plan uses the 5E learning cycle and is designed around an essential question: Why is the method you chose for landing your Rover on Mars the best one for your mission?

## KWL Assessment

In this final lesson of the Dancing Lights curriculum, students will reflect on and discuss what they learned about the aurora. First, students will compare what they know now with what they knew at the beginning of the program, and discuss their answers with a partner using Think, Pair, Share.
