In this paper and pencil exercise, students create graphs that describe the effect of a series of experiments using Daisy World, an energy balance model, that can be used to demonstrate concepts of equilibrium, homeostatis, and positive and negative... (View More)

This demonstration shows that an increase in temperature will speed up the water cycle. One outcome will be an increase in rainfall. A second outcome will be the increase in total evaporation of water and subsequent drought. Materials required... (View More)

In this activity, students observe how elastic rebound creates waves, using an apparatus consisting of a plastic tub and paint stir stick. The resource is part of the teacher's guide accompanying the video, NASA SciFiles: The Case of the Shaky... (View More)

In this activity, students build a model system using a rectangular pan, clay, craft sticks and water, and learn that energy is required to initiate waves and demonstrate that frequency is the number of waves that pass a given point in a certain... (View More)

This demonstration will show how increased temperatures will hasten the melting of ice in the environment, contributing to a rise in sea level and subsequent flooding of coastal areas. Materials required include 2 aquariums, plastic wrap, a clamp... (View More)

In this problem-based learning activity, students conduct research to determine the potential impact of a changing climate on maple sugar production. Student worksheets, a teacher guide, and an assessment rubric are included. The activity is... (View More)

In this demonstration, students explore the concept of greenhouse warming. They determine whether an increase in the amount of heat-trappping gases in the atmosphere can cause the temperature on Earth to rise. Students compare the relative heat... (View More)

In this activity using an open space and a thick rope, students simulate the movement of photons from the Sun. The resource is part of the teacher's guide accompanying the video, NASA Why Files: The Case of the Mysterious Red Light. Lesson... (View More)

In this activity, a balloon, flour, pebbles and a funnel are used to create a simulation of a meteorite impact. Balloons containing flour and pebbles are thrown onto a hard surface and students note the pattern of impact and draw it in their... (View More)

Using this worksheet, students learn to differentiate between wind speeds by using the Beaufort Scale of Wind Force. They are presented with a table describing the Beaufort scale, and then assign the appropriate scale to different weather events... (View More)
