From Brazil to Indonesia, young scientists investigate the geography and climate of the world's tropical rain forests with this collection of worksheets.

In this rain forest worksheet, students use different basic math skills to calculate the percentage of Earth covered by rain forests today compared to fifty years ago. They study the effects of how cutting down trees contributes to water...

Ninth graders research the average temperature and precipitation of a prairie region to determine the type of climate it is, and how it differs from other biomes. They examine the types of adaptions animals have made to live in the...

Students collect data on causes of Acid Rain. In this science lesson, students simulate the effects that produce acid rain, collect and analyze data from their samples. They relate science and statistics in this lesson.  

Students discover how to "read" tree rings to determine the date of a volcanic eruption and the effects an eruption has on plant growth. After a lecture/demo, students utilize a worksheet imbedded in this plan to date an eruption.

Learners study stream speed.  In this stream speed lesson students complete an activity and formulate an opinion and study its effects.

Students bag trees to determine the mass of the water given off in the evapotranspiration process.

First graders go on a water walk, collect weather data, and measure rainfall for a month. They examine the water cycle in this series of lessons.

In this multiplication practice activity, students sharpen their problem solving skills as they solve 6 story problems that require them to multiply with 3.
