In this activity, students build a basic understanding of how a sling psychrometer is used to determine relative humidity and learn how to read a chart to determine this relationship. In addition, the student will become familiar with the concept of dew point. Materials need to conduct the investigation include two thermometers, a wooden dowel, wood screw, two washers, a section of plastic straw, and a hollow shoelace. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 11 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.

Learners will read or listen to a story about two sisters, Marisol and Sofia, as they explore the Sun's role in the water cycle. Additionally, numerous extension resources are included in the accompanying educator guide, such as suggestions for no-cost language arts activities, links to further science activities, a book walk cue chart to guide classroom discussion before, during, and after the story, a graphic organizer, and alignments to the National Science Education Standards (NSES) and the Next Generation Science Standards (NGSS).

Groundwater is one of the largest sources of drinking water, so environmental engineers need to understand groundwater flow in order to tap into this important resource. Environmental engineers also study groundwater to predict where pollution from the surface may end up. In this lesson, students will learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow.

We will go below the surface and learn how water chemistry plays an important role in the Rain Shadow Effect. First, check out the Watershed Council Director video to learn how the Powder Basin Watershed Council is supporting efforts to restore their rivers, streams, and lakes in an arid part of Eastern Oregon. In the Discovery Challenge video, explore and learn how water chemistry plays a role in the rain shadow effect causing Eastern Oregon to not get nearly as much rain as Western Oregon.

This lesson introduces NGSS standards, and those standards are listed in the lesson and is part of the Explore Science Club series, an online Career Connected Learning program developed by the Greater Oregon STEM Hub. To learn more find us at: www.go-stem.org.

The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. ... The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.

This lesso material includes the water cycle along with the three main keywords ( evaporation , condensation , and Precipitation) explained.

The water cycle game helps you learn how water molecules move through various places including rivers, the ocean, the earth’s surface, the atmosphere and clouds. Actions such as evaporation, runoff, condensation, precipitation, soil absorption and ground water expansion move water from one zone to another.

This is a hands-on lab activity about the water cycle, specifically evaporation and condensation. Using materials such as clay, ice and a lamp, learners will observe the relationship between temperature and condensation and temperature and evaporation. They will then draw a diagram or a concept map of the water cycle. Background information, common preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities.

Students use a thermal process approach to design, build and test a small-scale desalination plant that is capable of significantly removing the salt content from a saltwater solution. Students use a saltwater circuit to test the efficiency of their model desalination plant and learn how the water cycle is the basis for the thermal processes that drive their desalination plant.

Students learn about the Earth's water cycle, especially about evaporation. Once a dam is constructed, its reservoir becomes a part of the region's natural hydrologic cycle by receiving precipitation, storing runoff water and evaporating water. Although almost impossible to see, and not as familiar to most people as precipitation, evaporation plays a critical role in the hydrologic cycle, and is especially of interest to engineers designing new dams and reservoirs, such as those that Splash Engineering is designing for Thirsty County.
