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)

This demonstration allows students to visualize inversion in a fluid, explain it in terms of density, and apply the concept to weather systems and convection. Materials required include four Ehrlenmeyer flasks, two thin glass plates, a heat source,... (View More)

Audience: High school
Materials Cost: $5 - $10 per group of students

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 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)

This is a lesson about how and why ice flows, especially in a large mass such as a glacier. Learners will experience the qualities of viscoelastic materials and view videos of glacial ice flows. They will observe ice flows and materials other than... (View More)

In this activity, students create a reservoir model using hoses, a bucket, a flat pan, and water, to understand the inputs and outputs of a local watershed or reservoir. The resource is supported by teacher background information, assessment... (View More)

In this demonstration, students learn that heat makes air expand and rise, and learn how pressure systems are formed by observing the creation of a convection current. A large rectangular pan, a salad dressing bottle, a small latex balloon and water... (View More)

This demonstration allows students to visualize how heat moves through convection - using water, food coloring, a small cup and a large jar - and prompts them to make a connection between the observed process and cloud formation. The resource is... (View More)

In this demonstration, students learn that air flows from a high-pressure area to a low pressure area, and greater the differences between pressure areas, the greater the wind speed. The demonstration uses an apparatus made from two 2L beverage... (View More)
