Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Young scholars explore water bodies on the planet Earth and their various uses and qualities. They examine several ways that engineers are working to maintain and conserve water sources and think about their role in water conservation....

Students examine the phases of the water cycle and water's different forms it can have. They work in groups to create pantomimes to illustrate the water cycle to their classmates.

Learners create a model to explore the water cycle. Students also perform different experiments to witness water changing from a liquid to a gas. Learners are asked to if they can find ways for water to go away without pouring the...

Students describe how water exists on earth in three states. They trace the path that rain water follows after it falls. Students describe various forms that water takes on the earth's surface and conditions under which they exist....

Students, in groups, explore ecosystems, water cycle, rock cycle, and food web. They create a puzzle piece on white butcher paper based on their information.

We are very dependent upon other life forms around us to survive. Here, scholars explore relationships in the ecosystem with the help of Auntie Litter and the pollution patrol. They imagine a world without grass, making connections to...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

High schoolers design and conduct an experiment to compare the water-holding capacity of sand, soil, and moss. They measure the change in weight for each material after adding the same amount of water to each material.

Learners complete an experiment. For this precipitation lesson, students complete an activity where they make rain in a jar.

Second graders examine the characteristics of animals who live in a pond environment. In groups, they describe the various stages in the life of a frog and identify the characteristics of other pond animals. Using this information,...

Students plant seeds, observe and tend plants. They identify major plant parts, how to germinate and troubleshoot problems with plants; and, that plants need water, light, and soil nutrients to thrive. They create a Plant Growth Data Log.

Students analyze data from monitoring activities . They summarize, post, and present the data from activities. They tell others in the community what they've learned about local water quality.

Students conduct hands-on experiments. In this life cycle lesson, students are able to observe a variety of animals as they travel through their life cycle (brine shrimp, mealworms, frog eggs and chicken eggs). Students respond to what...

Learners explain how uneven heating of Earth affects wind and water currents. They describe the limits on current technology in predicting weather and how the Water Cycle is related to local weather.

Students perform several water quality tests on groundwater from their area. They use test strips to determine the pH, hardness, alkalinity, nitrates, iron and chloride levels.

Students apply cause and effect relationships to water pollution in a stream. For this pollution lesson students recognize the importance of clean water in their daily lives. Students accompany "Fred the Fish" as he travels down stream....

Students review various scenarios in regards to the water cycle to determine what the best solution is to the problem. Students write their opinions on the controversies.

Students are introduced to rainfall measurement and develop a network of rain gauges. Students measure rainfall, plot rainfall maps and calculate total rainfall volumes during rainstorms.

Students draw and label the four parts of a plant. They describe changes that are part of the common life cycle. Students follow various one and two step directions. They are asked to discuss that they can recall about plants.

Students define the hydrologic cycle, define transpiration, name the three parts of the hydrologic cycle, and record the amount of moisture given off by several green plants.

Fourth graders explore the plant life cycle. They discuss the sequence of events in the life cycle of the plant and illustrate how the life cycle never ends. Students explore the importance of water, sunlight, and nutrients during the...

Student learns about the life cycle of plants by watching a time-lapse video. This activity provides students with further evidence that all living things grow and change as they progress through their life cycle.

Third graders investigate the stages of animal life cycles. They examine an egg and compare it to an inanimate object, read a booklet about the life cycle and define key vocabulary terms, and observe a mealworm. Students then design a...
