This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (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)

Students will explore the difference between the three types of contrails. Then they will make observations of contrails outside, and record their observations. Fifteen minutes later they will make follow-up observations to see how the contrails... (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)

In pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish plants as... (View More)

In this lesson, students analyze land cover change in order to help them grasp the extent, significance, and consequences of land cover change; and to introduce them to the perspective of space-based Earth observations. Students learn to identify... (View More)

This is a lesson where learners engage in a radiating heat activity and an activity that measures temperature in models with and without greenhouse gases. Learners will draw conclusions about the effect of greenhouse gases on temperature and on... (View More)

This is an activity about the Earth-Moon system. Learners will build a scale model of the Earth-Moon system and predict the distance between the two, as well as the distance of Earth-orbiting spacecraft.
