Students, using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, observe and record the role of light in photosynthesis. They consider plant production of carbon dioxide and the use of live materials in biological...

Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...

Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...

Middle schoolers use the blooming of tulips as a tool to measure spring's journey north. They predict when tulips bloom at 13 selected Journey North gardens in various geographic regions.

Student role play and draw the various stages an insect goes through to become a butterfly. They discover the different stages of how a caterpillar becomes a butterfly. Young scholars read The Very Hungry Caterpilla by Eric Carle.

Students discuss the threats facing migratory species and track the seasonal journeys of wildlife in real space and in cyberspace. Once they have gathered information from several sources, they create a portfolio to share with others...

Students explore the effects of ultraviolet light on Lumbriculus. They expose ultraviolet light to Lumbriculus (worm) and determine the lethal exposure time. They examine the worm and record their observations.

Students observe changes in a selected tree bud/leaf during spring. They record changes in the bud/leaf using words, pictures and numbers. They understand that trees adapt to changes in temperature, light, and moisture by sprouting leaves.

Students measure a topographic and geologic cross-section across a floodplain using simple surveying and auguring techniques in a field lab. Students also reconstruct the history of a river system.

Young scholars examine and then discuss opposite sides of controversial issues such as neighborhood curfews, lowering voter age, etc. They learn civic responsibility and cultivate tolerance for others' opinions.

Learners predict the movement of an air borne pollutant using their understanding of air currents. They determine which governments and/or communities should be contacted to be forewarned. They also explore the properties of their...

Learners observe how to classify things into groups based on physical properties.  In this plastic and rubber lesson students group and sort items to help them to better identify properties. 

In this water cycle activity, students investigate the evaporation process by participating in an outdoor evaporation experiment held on the school grounds. Students will determine where evaporation takes place the fastest and how nature...

Students apply their understanding of the natural water cycle and the urban stormwater water cycle, as well as the processes involved in both cycles to hypothesize how the flow of water is affected by altering precipitation.

Students develop an understanding of the water cycle and water catchments. This learning module is divided into introductory, developmental, and culminating activities, and also has several assessment strategies. Resource sheets...

Activities demonstrate how the water cycle maintains itself.

Activity helps with understanding the water cycle.

Learn about the water cycle through the adventures of two sisters. They will explain how the sun powers the water cycle and describe the different states of water. A glossary and labeled illustrations accompany the video. For the...

In this activity, you will investigate some of the processes that make water move in and out of the atmosphere by making a miniature water cycle model inside a plastic bag.

In this lesson, students unite science and physical activity to learn about the water cycle!

This tutorial includes interactive activities, videos, and teacher notes for a unit on the water cycle.

In this science activity, students 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 water...

Watch an animated video on the water cycle, become familiar with related vocabulary terms, and then quiz yourself on the parts of the water cycle, and review your answers when you're done. Site includes guidelines for a lesson entitled...

This water cycle activity is designed to assess the comprehension of concepts related to the water cycle.
