## Afterschool Universe

This astronomy program is designed for middle school children in out-of-school-time settings. The program explores basic astronomy concepts (like invisible light, telescopes) and focuses on the universe outside the solar system (stars, galaxies, black holes).

## Ratios, Proportions, Similarity

This is a set of one-page problems about the size of planets compared to Earth. Learners may use ratios to compare planets within our solar system or those outside of our solar system with the Earth.

## Learning from Slide Rules

This resource describes the slide rule as an analog computer, and uses the slide rule to demonstrate the concept of isomorphism, which is one of the most pervasive and important concepts in mathematics.

## Towards a Sustainable World

Readings in this chapter guide student reflection on sustainability of the planet, and whether the Earth system is near a tipping point, where ecosystems will reorganize and seek a new equilibrium, with consequences for biodiversity.

## MRC: Investigate Mars (Grades 3-5)

This lesson plan uses the 5E learning cycle and is designed around an essential question: How do I know when I’ve found important information in my reading?

## Introduction to Magnetism

This is an activity about magnetism. Learners will experiment using horseshoe and bar magnets along with various materials in order to identify the effects of magnets on each other and on other materials.

## Astro101 Slide Set: Debris Belts around Vega

This slide set focuses on the discovery of debris belts around Vega. It is one of a series of short, topical presentations on new developments from NASA astrophysics missions, relevant to introductory astronomy topics.

## How to Hold a Dead Star in Your Hand

Follow the 400 year background story leading to the creation of the first 3D model of a supernova (Cassiopeia A). This article explains how science, mathematics and technology led to the visual representation of data gathered by NASA's Chandra X-ray Observatory.

## What Makes a World Habitable?

This is a lesson about the characteristics necessary for life. Learners will identify the top candidates for life in the solar system by examining Habitability Cards, which discuss each planet and the six large moons in terms of water temperature, atmosphere, energy, and nutrients.

## Identifying Unusual Galaxies

In this activity, students match unusual galaxies with their distinctive names and justify their reasoning. Students discover that often, galaxies acquire their names based upon how they appear to observers.
