Students study the aspects of a forest floor ecosystem, including decomposition, the water cycle, food webs, the needs of living things, and physical vs. chemical change over an extended period. In addition, students conduct observations...

Students explore about and evaluate the potential impacts of climate change on northern hydrological systems. They work in small groups, research the background to climate change in the north with a particular focus on lakes and rivers.

Young scholars identify the changing states of water, water vapor and ice in the water cycle They investigate how each of these stages can be reversible. Students complete a worksheet describing the water cycle.

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

Seventh graders identify how much carbon is held by the world's forests. For this forestry lesson, 7th graders study the carbon cycle and discuss what role humans have had on climate change. Students write a one page paper on how...

Fourth graders explore weather patterns by completing an Internet project. For this water cycle lesson, 4th graders read assigned text including a Magic School Bus book about precipitation and water. Students complete a water science...

Students explore water and how it changes forms.  In this investigative instructional activity students participate in an activity that shows them how water changes form and what it looks and feels like. 

Students explore forms that water can take. In this science lesson, students participate in hands-on activities that require them to change water to a solid and back to a liquid again.

Young scholars explore the parts of the rock cycle and the process of erosion as they build their own mountain and observe the effects of wind and rain as erosive agents.

High schoolers 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.

Students examine water as it changes states.  In water and ice lesson students study the water cycle and what happens to it as it changes state. 

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. Student conducts a...

Fifth graders practice interpreting line graphs of the Hudson River water levels to assess the tides and tidal cycles in the estuary. They explore how weather can affect water levels and tides and observe that high tides and low tides...

Students conduct various experiments to investigate plant transpiration. In this biology lesson, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.

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

Students examine the journey of the Pacific salmon. In this salmon species lesson plan, students review the stages of the salmon life cycle and conduct an experiment to determine how the water and habitat changes during each stage.

Students conduct hands-on experiments. In this life cycle instructional activity, 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...

Become a member of the Pollution Patrol and stand up to litter! After discussing the life cycle of seeds and discussing how plants figure into the food chain, young conservationists engage in several activities involving podcasts,...

If you are new to teaching agriculture classes, this outline may be helpful when you are preparing a lecture on parasites in livestock. In addition to lecturing on this topic, the lesson plan suggests that learners research the life...

Fourth graders write a story about how a drop of water may have traveled to school. They design a presentation on the water cycle.

Students investigate the water cycle and evaporation. They study the porosity and permeability of groundwater, and the capillary action in soil in this unit.

Students explore Afro-American history. They identify the commonality between African, Carolinian and Cleveland Black culture. Students explore the water cycle, oceanography, hydrology and bio-geochemical processes. They discuss the...

Students examine the major concepts related to the water cycle in this lesson. They recognize and define evaporation, condensation, precipitation and the natural cycles that occur as weather. They also participate in an activity of...

Young scholars explore the seasonal changes in Costa Rica.  In this dry season instructional activity students use the Internet to locate science data then generate data for precipitation.
