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.

Young scholars 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...

Second graders observe the changes that water has when there is a change in a state of matter. In this lesson they observe the results of applying heat to water with the end result of conversion to a gas.

Students seek scientific and technological solutions to envrionmental problems. They record class activities in a journal. They identify relationships among living things and their environments.

In this environment activity, learners take part in a variety of activities that includes an experiment, word search, and readings related to the watershed.

Young scholars are introduced to the concepts of a watershed, stream flow and water quality. This five-day plan is an excellent way to introduce students to the concepts involved. They create their own watershed using a paper bag, water...

Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the lesson plan, they review the steps of the water cycle and...

Fifth graders explore changes in nature. They identify chemical and physical changes in the water cycle, carbon cycle, and weathering. Students explore a chemical or physical change based on a chemical formula. They examine the effects...

Stimulate interest in ocean currents with a simulation. The first installment of a five-part middle school series teaches future oceanographers about the forces that interact to cause ocean currents. A simulation shows how wind and...

Learn about defensible space and renewable resources with a lesson about forest fires. After exploring the ways that humans have impacted the environment, kids conduct mock interviews about differing points of view in the conservation...

Third graders study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

First graders study sunflower plants and identify its parts. They plant sunflower seeds and watch them grow and make sunflowers out of paper plates and colored paper. They watch videos and visit websites about sunflowers.

Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...

Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities: Measurement of the mass and volume of fruit in order to compare densities Measurement of the mass of oil and water...

Students work together to identify marine debris. They explain the effect of the debris on various ecosystems. They draw different types of ocean currents as well.

Students explore the life cycle of shrimp. In this life cycle lesson, students research the different stages of a shrimp's life cycle. Students examine threats to the species in each stage of life.

In this water worksheet, students answer 10 questions about Florida's water. Students also describe the role of ground water and sinkholes.

Students read and conduct and experiment to learn about rain formation. In this water forms lesson, students read about the formation of rain and its purposes. Students then complete a rain experiment activity.

Students are led through three activities to explore the effect of temperature fluctuations on the growth and survival of aquatic plants, clams, and shrimp eggs.
