## What are the Consequences of Global Warming?

In this textbook chapter, sea level rise, ocean acidification, storm surge, desertification, ecosystem loss, and extreme weather are all discussed, along with economic and social costs to society. A video clip of NASA scientist, Dr. Tom Wagner, discusses sea level rise.

## Jupiter: Largest, Fastest and Strongest Fact Litho

This is a lithograph about Jupiter. It describes basic facts about Jupiter and the missions that have visited it.

## What is Wind Chill?

This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept.

## Secchi Disk Interactive

Learn how to build a Secchi disk and use it to make water transparency measurements following the GLOBE protocol for water transparency measurement with a Secchi disk. This resource is part of the GLOBE Program Hydrosphere Protocol eTraining.

## A History of Forest Use in the Pacific Northwest

This textbook chapter summarizes the changes in the ecosystems found in the world's forests. This is chapter 2 in the unit, A New World View, which introduces global systems science, emphasizing the concepts of environmental diversity, Earth as a system, and sustainability.

## Connecting Global Climate Change with Engineering

This self-paced tutorial explores the importance of engineering solutions to the management of climate change by brainstorming ways to remove CO² from the atmosphere and store it in a form that does not promote global warming.

## Pilots, Airplanes and Tangents of Three (3) Degrees

This exercise shows a practical application of trigonometry in the aviation environment, where student pilots consider the relationship between altitude and distance to complete a landing. It requires a scientific calculator.

## Integer Arithmetic

This is a set of one-page problems about the size and area of solar panels used to generate power. Learners will will use integer arithmetic to tally the number of hydrogen, oxygen and carbon atoms in a molecule and determine the number of methane atoms that can result.

## Changes to Permafrost Over Time

In this unit, learners discover that changes that affect permafrost ecosystems can happen over very long periods of time or very short periods of time. Permafrost can be monitored over time by analyzing geological, archaeological and paleontological evidence.

## Constellation Quest

This is an activity about identifying constellations. Learners will look for constellations in the Sky Tonight online program, draw images of these constellations, and attempt to find them in the night sky.
