The purpose of this resource is to understand what causes the Earth's seasons with a focus on the Earth's tilt and spherical shape. Students learn how sunlight spreads over the Earth at different times of the year, emphasizing the solstices and the equinoxes. Students investigate the effect of the Earth.s tilt on the spread of sunlight by modeling different tilts using a three-dimensional polyhedron ... Full description.

The purpose of this resource is to further students' understanding of the causes of seasonal change using visualizations to compare the effects of incoming solar energy in the two hemispheres. The class reviews global visualizations of incoming sunlight and surface temperature and discusses seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in ... Full description.

This activity helps students to understand the many roles that polar sea ice plays in the systems that maintain our planet, by first helping them to understand the process of the formation of ice in oceanic regimes. Students will use an inquiry based lab experience relating salt content to the ability of water to freeze in order to begin this study. Specifically, they will design an experiment to ...

This site provides information about precipitation, evaporation, condensation, surface runoff, infiltration and transpiration, which are all part of the water cycle, a complex process that not only gives us water to drink and fish to eat, but also weather patterns that help grow our crops. The site has four sections. The introduction presents the overall concept while the second section covers each ... Full description.

This explanation of the hydrologic cycle discusses evaporation, transpiration, condensation, precipitation, runoff, percolation, groundwater, and the water table. There is a diagram and a description of each as well as a discussion of the dynamics of the cycle, which powered by the Sun. In addition there are links that lead to all parts of the Properties of Water menu. Full description.

This experiment helps students understand that ultraviolet (UV) radiation is present in natural outdoor light and that the intensity of the light varies with season and time of day. After completing this activity, students will be able to demonstrate that UV radiation can be blocked or filtered by various substances. The page contains detailed background material, learning goals, alignment to national ... Full description.

Comment on this resource
In this activity, students will be reminded that when sunlight strikes the Earth's surface, energy is absorbed and the surface material is heated. But although the same amount of sunlight strikes different materials at a given location, they heat up at different rates. Students will use models to demonstrate conduction, convection, and radiation and to gain an understanding about what happens to create ... Full description.
