Students are introduced to the Global Precipitation Measurement (GPM) satellite mission and its role in studying the water cycle. This webquest provides links to eight websites, allowing middle school students to explore the water cycle and its... (View More)

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... (View More)

In this lesson, students will learn about the water cycle and how energy from the sun and the force of gravity drive this cycle. The emphasis in this lesson will be on having students understand the processes that take place in moving water through... (View More)

This is a hands-on lab activity about the properties and states of water. Learners will complete activities using different liquids to understand the three states of matter, explain how the high heat capacity and abundance of liquid water makes life... (View More)

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... (View More)

This is an activity about the correlation between annual precipitation and plant productivity in different Earth biomes. Learners consider water evaporation, solubility and abundance relative to life on Earth and relative to finding evidence for... (View More)

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... (View More)

In this problem-based learning (PBL) activity, students take on the role of a student research scientist and explore the role of solar energy in determining climate. Students conduct experiments to observe how a change in water phase affects surface... (View More)

In this activity, students analyze the results of an experiment, conduct research, and describe the potential importance of positive and negative feedbacks in governing the response of the Earth system. Teacher background information, assessment... (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)
