2. 9-1. Visuals often play an important role in helping an audience learn. At the same time, visuals seldom constitute all that an audience needs to learn. For this integration activity, you should identify a concept, process, or event whose learning can be enhanced through the use of visuals. After you have identified your topic, combine visuals with other instructional elements to create a presentation that will facilitate the learning expected of your audience. The presentation should be prepared in PowerPoint or an equivalent program and should contain as many slides as needed for the desired learning to occur. Also, in the Notes section of PowerPoint, identify the role that your visuals are expected to play in the learning process. The presentation of the images and elements should be consistent with the guidelines for preparing presentation graphics found on pages 74-75 in your text.

3. Concept: The Water Cycle • The water cycle is comprised of the following parts: • Evaporation • Condensation • Precipitation • Transpiration • Surface runoff • Accumulation

4. Evaporation • the process by which water is converted from its liquid form to its vapor form and thus transferred from land and water masses to the atmosphere.

5. Condensation • The process in which water vapor changes into a water droplet or ice crystals. This happens because water vapor in the air gets cold and changes back into liquid, forming clouds.

6. Precipitation • Precipitation occurs when so much water has condensed that the air cannot hold it anymore.  The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet, freezing rain, or snow.

7. Transpiration • Transpiration is the process where water contained in liquid form in plants is converted to vapor and released to the atmosphere. Much of the water taken up by plants is released through transpiration.

8. Surface Runoff • the water flow that occurs when soil is soaked to full capacity and excess water from rain, meltwater, or other sources flows over the land.

9. Accumulation • When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land.  When it ends up on land, it will either soak into the earth and become part of the “ground water” that plants and animals use to drink or it may run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again.
