Students begin by determining dew point using an aluminum can, stirring rod, ice and thermometer. Air temperature is also measured and recorded. Students then use those two data in conjunction with the Lifting Condensation Level approximation, to... (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)

Designed as a five-lesson curriculum to introduce students to limnology, this program explores the structure, history and biology of lakes. Students analyze models, images, and a core sample from a lake case study before engineering a device for... (View More)

Through an analysis of data sets on four parameters - sea ice totals, sea surface temperatures, near surface temperatures and surface type - students must decide whether the Arctic is experiencing climate change and predict any potential effects on... (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 a lesson about the formation of plasma bubbles in Earth's ionosphere. Plasma bubbles cause stars to twinkle and radio signals from satellites to distort. Learners will build a model ionosphere in order to demonstrate and understand this... (View More)

This is a lesson about the location of common Earth objects within layers of our atmosphere. Learners will construct a scale model of the atmosphere in order understand where the common objects, such as clouds, airplanes, and space shuttles can be... (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)
