Fifth graders investigate coral reefs and the dangers they face by labeling and drawing.  For this oceanography lesson, 5th graders view a PowerPoint presentation of photographs of coral reefs in Belize.  Students investigate...

Pupils describe the structural differences in the respiratory systems of aquatic and terrestrial vertebrates and explain the motivation for these structural adaptations in reference to the differences in habitat.

Students examine how sedimentary rocks are formed.  In this rock lesson students research different rock formations and different types of rock. 

Students investigate tides and the land submerged under them.  In this intertidal field trip, Students visit the intertidal zone and observe the habitats and animals that live there.  Students view the pools under rocks where...

Students examine how hormones affect different tissues. In groups, they make their own hormone-receptor model and identify the characteristics of tissues that respond to the different hormones. To end the lesson, they examine the role...

Students create a book about bats. They write a letter to a scientist containing questions about bats. They compare the socialization of bats to humans; compare the needs of bats to humans and other animals.

Third graders investigate Newton's law of Motion.  In this chemical reaction lesson, 3rd graders participate in an experiment with rockets to study Newton's law. Students observe the effects of a chemical reaction made by combining...

Students discover decomposition. In this environmental lesson, students explore different types of decomposers and their role within the ecosystem. Students also discover how waste interferes with the decomposition process.

Students examine the cause-and-effect relationship between tides and the rocky coast ecosystem. They complete a worksheet that illustrates the intertidal zone.

Students explain the parts of the body that are involved in breathing and explore lung function.  In this model lung lesson students make a model of a lung then interpret and explain it. 

Students calculate the calories in food samples and plan a meal based on the calorie amount. For this calories lesson plan, students also devise a work out program to burn off the calories.

Students discuss and evaluate the use of the Yin and Yang symbols in Chinese history, making connections to current trends in Chinese culture. Emphasis is placed on small group discussions.

The U.S. Geological Survey (USGS) and the Food and Agriculture Organization of the United Nations (FAO) have teamed up to create a water-cycle diagram for schools. Use the interactive version and download printable files of the diagram.

A quick summary of the water cycle that includes a diagram of the cycle, with links to in-depth explanations of each component of the cycle. Click "water-cycle home" to access water-cycle resources in a variety of languages.

Hyperlinked diagram provides an in-depth explanation of each phase of the Earth's water cycle.

An in-depth explanation of the Earth's water cycle, including a hyperlinked diagram that provides direct access to information about each phase in the cycle.

Presents a water cycle diagram with information about the different stages, a 10-question groundwater quiz, and a water poem.

In this science activity, young scholars investigate the water cycle by testing the water evaporated from leaves (transpiration). They investigate concepts of evaporation and the movement of water through the different states of the...

Learn about the movement of water from Earth's surface to the atmosphere with this site. Site describes the water cycle in words and with a diagram. Also explored on the page is the distribution of Earth's global water supply.

Describes the four main stages of the water cycle - evaporation, condensation, precipitation, and collection.

Through pictures, diagrams, and charts, learn how the ocean serves as a storehouse of water.
