In this activity, students will use a simulator of an orbiting X-ray observatory to observe a supernova remnant, the expanding gas from an exploded star. They will take X-ray spectral data, analyze them, and answer questions based on that data. This... (View More)

This is an activity about the correlation between annual precipitation and plant productivity in different Earth biomes. Learners consider water evaporation, solubility and abundance relative to life on Earth and relative to finding evidence for... (View More)

This article provides students with an overview of the technologies used to study the health of the Chesapeake Bay, which is at risk for eutrophication from non-point source pollution. The article describes how data from research vessels, buoys, and... (View More)

In this activity, students learn about the biological and physical conditions that lead to eutrophication of a water system by using real-time data to predict the the growth of harmful algae. They also conduct research on the Internet to learn more... (View More)

This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More)

The purpose of this investigation is to understand how the amount of water vapor in the air at various temperatures affects the way the human body responds. This is an important basic concept for understanding why one might feel either comfortable... (View More)

In this activity, students compare and analyze lapse rates (rate of decrease in atmospheric temperature with height) for two U.S. locations. It requires the use of atmospheric temperature data downloaded from the Internet into a student developed... (View More)

This chapter provides teachers with instructions to install a school weather station, and to build simple instruments to monitor weather conditions. Materials need to create a homemade weathervane include a two-liter soft drink bottle, a shallow... (View More)
