Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

Step-by-step, arrow-by-arrow, viewers are walked through the rock cycle. In the end, you have a simple, yet complete diagram of the process. Pictures appear to show samples of igneous, sedimentary, and metamorphic rocks. The presentation...

Students are introduced to the components and importance of the water cycle. They are shown how groundwater moves using a model. Students list 9 places on earth where water is found. They define the terms cycle and water cycle.

Students construct a model of the water cycle in action using two-liter pop bottles to build a terrarium. Locate examples of evaporation and condensation in the water cycle (e.g., water evaporates when heated and clouds or dew forms when...

Fourth graders create a biome of their choosing in a terrarium. Terrariums are observed and results recorded daily for 2 weeks. They observe/record changes in the water within their terrarium and use the data to write sentences...

Eighth graders record the temperature change of the beakers. In this general science lesson, 8th graders create their own data table for recording observations. They discuss experimental results and cite real life applications.

A course lecture on the external processes that shape the Earth, specifically the hydrologic system. This system is powered by the Sun's energy. The components of the Earth's energy budget are described, and how these drive the movement...

Almost all of the energy that drives the various systems (climate systems, ecosystems, hydrologic systems, etc.) found on the Earth originates from the sun. Solar energy is created at the core of the sun when hydrogen atoms are fused...
