The total amount of water on Earth, the places in which it is found and the percentages of fresh vs. salt are examined in this lesson. A short demonstration allows students to visualize the percentage differences and a coloring exercise illustrates... (View More)

Water is essential to Earth's living system, the biosphere. In this lesson, students determine the types of living things within an outdoor study site, use a taxonomic key to determine the predominant land cover type of their site, then predict the... (View More)

Students will design, build and then test a rain gauge to measure precipitation. By sharing their results, they will recognize the need for standardization and precision in scientific tools. All background information, student worksheets and... (View More)

With this lesson plan, students observe a demonstration of cloud formation that uses a 2L plastic beverage bottle and other simple ingredients to learn the three factors required for cloud formation. A test and a control experiment are conducted.... (View More)

Cloud cover is a fundamental observation in the S'COOL project. The ability to reasonably estimate the percentage of cloud cover is introduced and practiced in this activity. The Students' Cloud Observations On-Line (S'COOL) project engages students... (View More)

The purpose of this investigation is to understand the change that takes place when water condenses from a gas to a liquid, and how a change in pressure affects this transformation. Materials needed for the experiment include a large (2L) soda... (View More)

This is an activity about the periodic reversals of Earth's magnetic field. Learners will graph the frequency of magnetic pole reversals over the past 800,000 years and investigate answers to questions using the graphed data. This is Activity 8 in... (View More)

Students learn to identify and communicate important patterns in a dataset by drawing a visualization, and begin to interpret those patterns. Resource includes a student data sheet and scoring rubric. This learning resource is part of the Atmosphere... (View More)

In this activity, students work in teams to calculate relative air mass and demonstrate how solar elevation angle affects the intensity of light that reaches an observer on the ground. The resource includes a student data sheet. It is part of the... (View More)

Students observe cloud type and coverage and weather conditions over a five-day period and correlate these observations. Students make and test predictions using these observations. This is a learning activity associated with the Atmosphere chapter... (View More)
