## Technology Teacher: Evil-doer or Do-gooder - Getting the Goods on Ozone

This article discusses the differences between ozone in the stratosphere and troposphere, and how NASA is measuring ozone using a spectrometer on-board the Aura satellite. The article includes an activity: building a spectroscope using a DVD cover and inexpensive materials.

## Measuring Time

This is an activity about the measurement of time. Learners model the rotation of Earth over one day by holding a flashlight for the Sun and a blow up globe, and record their observations. Then, they use those observations to create devices that will track time and test their devices outside.

## Interpreting Graphs

Students will learn about the temperature change of Earth during the 20th century and through 2010. They will read a NASA press release describing recent trends in global climate change since 1900, and view a NASA eClips™ video segment about the energy budget of Earth.

## What Can We Believe? The Daily Shooting Star

This is a lesson about discerning fact and fiction in news articles. Learners will read tabloid articles about meteorites and decide if the information is fact or fiction. Questions, extensions, and advanced preparation and procedural tips are included.

## The Declining Magnetic Field

This is an activity about the declining strength of Earth's magnetic field.
