## Star Light, Star Bright? Finding Remote Atmospheres

This is a lesson about detecting atmospheres of planets. Learners will explore stellar occultation events (by interpreting light curves) to determine if an imaginary dwarf planet "Snorkzat" has an atmosphere.

## We All Need Soil!

Each student will explore three activities that promote understanding of and respect for soil.

## Earth System Responses to Natural and Human Induced Changes (Grades 10-12)

This unit focuses on local plant species; students learn to identify common species and will examine their life cycle characteristics as evidence of climate change.

## Newton's First Law of Motion: Inertia and Unbalanced Forces

This educational wallsheet illustrates Newton's First Law of Motion. In the related activity, students will discover the properties of inertia and motion, and see how they have very important real-life applications.

## Climate Kids: Planet Health Report: Sea Ice

One of Earth's vital signs, the extent of sea ice cover in the Arctic, is examined. An image and accompanying text describe the extent and consequences of the reduction in that sea ice.

## Climate Kids: It's Cold! Is Global Warming Over?

The movement of Arctic air, known as the Arctic oscillation, can and will cause periodic extreme winter weather outside the Arctic region - the harsh winter experienced in many parts of the U.S. in 2010 is a recent example. This article explains the connection between the two events.

## SciJinks: Whirlwind Disaster

This article discusses how hurricanes form, are named and categorized. An online game related to hurricanes is included, as is a short video featuring Hurricane Katrina.

## S'COOL Lesson: The Sky and the Dichotomous Key

In this field activity, students observe clouds, and are introduced to dichotomous key to classify cloud types. Students also make weather observations of current weather and record and track changes in weather over time.

## Dusty Dilemma

Learners will be introduced to the concepts of error analysis, including standard deviation. They will apply the knowledge of averages (means), standard deviation from the mean, and error analysis to their own classroom distribution of heights.

## MY NASA DATA: Hurricanes as Heat Engines

In this data analysis activity, students explore how hurricanes extract heat energy from the ocean surface by tracking Hurricane Rita and sampling sea surface temperatures along its path.
