## How Did They Form? Building Blocks of Planets

This lesson is about meteorites. Learners will experiment with simulations that illustrate how chondrites and asteroids formed in the early solar system. It is intended for learners to observe and describe the meteorites in the Meteorite Sample Disk.

## Transit Math

This is a collection of mathematical problems about transits in the solar system. Learners can work problems created to be authentic glimpses of modern science and engineering issues, often involving actual research data.

## GLOBE Data Explorations

A collection of nine atmospheric science and geography activities that guide students in developing the skills used to analyze GLOBE environmental data. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.

## The Cosmic Ray Telescope for the Effects of Radiation (CRaTER)

In this lesson, students will explain CRaTER's purpose and how it works. They will also design (using paper and pencil) a cosmic ray detector to answer their own questions.

## Fractions and Chemistry

In this problem set, learners will practice fractions by working with the ratios of various molecules or atoms in different compounds to answer a series of questions. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.

## What's Getting Through To You?

In this activity, students are introduced to light and colored gels (filters).

## Accidental Discoveries

In this activity, students research scientific discoveries that happened by accident in the past, and learn how gamma-rays were discovered by 20th century scientists. In the process, students develop an understanding that science theories change in the face of new evidence.

## Observing Visibility and Sky Color

Students become aware of the changes in visibility and sky color due to particles suspended in the air, called aerosols.

## Resolution Matters

This is an activity about image resolution. Learners will recreate a solar image taken by the Solar Dynamics Observatory (SDO) using various sizes of building bricks, and discuss how their recreations relate to image resolution.

## The Cause of the Earth's Seasons

This lesson attempts to correct the common misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. Proceeding from student preconceptions, small groups participate in an exploration of the cause of the seasons using a basketball, small globes and a lamp.
