Third graders examine the natural circulation of water from oceans, lakes, and rivers to evaporation into the air, and then to condensation to produce rain falling back to the soil as components of the water cycle.

Middle schoolers discover ways to preserve the Earth's resources. In this natural resources lesson, students investigate how many gallons of water the average American uses per day and then total their estimated usage. Middle schoolers...

Students explore the rain forest and where they are located. Students examine why the rain forests are important and what is happening to them. They investigate the water cycle and life cycle of a frog. Students build a rain forest in...

For this biosphere worksheet, students identify the different levels of organization that ecologists study. Students complete charts, sentences, and answer short answer questions.

Students construct a weather dial. In this weather lesson, students examine different types of weather and design a weather dial for use during the daily math meeting.

Students listen a variety of books on butterflies and are introduced to their life cycle. In groups, they describe the life cycle in the correct order and watch the life cycle from larva to the butterfly in a demonstration. To end the...

Students search stream beds to study the life cycle and adaptations of stream insects. They explore creeks and streams to see the diversity index of creeks or streams and to find the water qualit index.

Students explore the differences in sedimentary, metamorphic, and igneous rocks. They discuss the rock cycle of the different formations. Students discuss how rock is formed into different shapes. They explore, predict, and create each...

Students observe the life cycle of a frog.  For this life cycle lesson, students will observe and record the changes in the life cycle of a frog.

Middle schoolers investigate the concept of erosion by water in a problem solving activity. In small groups, they are assigned either sand, potting soil or rocks to construct a mountain that will hold up to a sprinkler can of water...

Students learn about the biological carbon cycle. In this carbon cycle lesson, students access the web site and mouse over the diagrams to follow the carbon cycle. They read about what happens to humans and plants during this cycle.

Students engage in a lesson of investigating the amount of water that is transpired in a one day cycle. They conduct research to find the purpose of transpiration and find information to explain the value to a plant and explain how...

Second graders explore how to identify cloud types by observing clouds. They record data and have fun by applying newly acquired knowledge throughout the curriculum.

In this crossword worksheet, students complete a 9 word crossword puzzle about the life cycle of the frog, accompanied by pictures.

Students investigate the concept of weather and how it is created. They review relevant vocabulary related to weather. Students predict weather given slight background knowledge. The lesson includes background information for the...

Students discuss pollution and the steps in the hydrologic cycle. They follow a drop of water through a watershed simulation. They discover the components of a water cleaning system as well.

  Learners observe a leaf and discuss the way that water is released from a leaf through its stomata.  For this water cycle lesson, students calculate how much water leaves produce from a whole tree.     

Young scholars examine soil. For this earth science lesson, students define and describe weathering and erosion as it relates to soil. Young scholars compare and contrast potting soil with forest soil and complete a science observation...

Fourth graders review the parts of the plant and their functions.  In this plant lesson, 4th graders recognize that plants must transfer energy to make food.  Students understand the interdependence of organisms in an...

Seventh graders take an outdoor observation walk around the campus and take soil samples. Working in groups , they conduct experiments with rocks and soil that demonstrate the effects of different types of erosion.
