Intended for use prior to viewing the Science on a Sphere film "Water Falls," this lesson introduces students to Earth's water cycle and the importance of freshwater resources.

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)

Each student will explore three activities that promote understanding of and respect for soil. They will generate responses to the following questions: "What makes up soil?" and "What lives in the soil?" Next the students will watch a demonstration... (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)

Students determine the moisture content of a sponge after squeezing the water out of the sponge, and allowing water to evaporate from the sponge. Students also measure the amount of water that has evaporated from the soil samples. This learning... (View More)

In this field activity, students learn about the five soil-forming factors and their influence on soil properties such as moisture, temperature, color and texture. They identify factors such as slope, shade, plants and compaction, and investigate... (View More)

Students will work in teams to create visual models to assist in understanding the volume of surface ozone in the air. Students construct cubes of different volumes and compare them to get a feel for parts per million by volume and parts per billion... (View More)

This is a lesson where learners explore plate movement and the relationship between plate tectonics and volcanoes. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes, prerequisite concepts, common... (View More)

In this activity, students observe and sketch clouds, describing their forms. They will initially generate descriptions of a personal nature and then move toward building a more scientific vocabulary. They correlate their descriptions with the... (View More)
