Hurricane Katrina serves as the focus for this lesson on the relationship between sea surface temperatures and hurricane intensity. Students assume the roles of Senior Science Advisors for the Louisiana Environmental Agency to research and plot the... (View More)

Audience: High school
Materials Cost: Free

This lesson incorporates sea surface data collected by NASA satellites. Data for three surface characteristics- height, temperature and speed- are used for several activities. Students examine the differences in speed of currents relative to... (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)

This is a lesson about the formation of glaciers, ice layering and stratigraphy, and the cryosphere and cryobotics. Learners will collect evidence of layering, explore the science story that layering tells, study snow and ice for insights into... (View More)

This experimental activity is designed to develop an understanding that air has mass. Students conduct an investigation and observe the change in the position of a bar balancing a balloon inflated with air on one end and a uninflated balloon on the... (View More)

In this activity, students monitor the change that takes place when water vapor condenses from a gas to a liquid and see how a change in temperature affects this transformation. Materials needed to conduct the investigation include two thermometers,... (View More)

This experimental activity is designed to develop a basic understanding of the relationship between temperature and pressure and that a barometer can be constructed to detect this relationship. Resources needed to build a simple barometer include a... (View More)

This activity promotes student understanding of some of the movements that take place when warmer water and cooler water interface, and how differences in densities, resulting from variations in temperature, set molecules of liquids and gases in... (View More)

This is a lesson about condensation, snow and snowflakes. Learners will investigate how water and ice exist in the atmosphere as they study water vapor condensing, find that clouds are made of tiny droplets of water, and notice that snow forms in... (View More)

This chapter provides a series of investigations, ranging from teacher-centered to open inquiry, that involve the formation of clouds in a model cyclone, and demonstrating how the availability of heat (indicated by temperature) affects formation and... (View More)
