Students explore the surface ratio of an object.  In this surface area to volume activity students construct a data table, make calculations and create a graph. 

Ninth graders study the climate regions of Europe. For this geography skills lesson, 9th graders determine how weather and climate are influenced as they research the climate zones of specific locations and write about the ways that...

Third graders identify a cloud and explore how they form. They create an acrostic poem about clouds.

Pupils explain how water changes from vapor to liquid with a change in temperature by engaging in this experiment. They use a worksheet imbedded in this instructional activity to guide their inquiry.

Third graders examine the power of solar energy. In groups, they create their own pizza box solar oven to discover the power of the sun and how it is a source for heat and light. To end the lesson, they use the internet to examine...

High schoolers explore the process of combustion.

First graders observe while water is absorbed into a sponge. They experiment by putting a sponge on yardstick and watch while water dries and the weight changes.

In this soil conservation activity, students study and analyze two excellent ways to enhance soil conservation: compost heap and leaf-mould. Students review all the ingredients in making both.

In this activity, students investigate how condensation causes moisture to form on the outside of a cold cup. To see if the condensed water vapor comes from the air, students use 2 cold cups, but limit the air around one of them by...

Regardless of the time of year or region of the country students live in, they have likely experienced moisture on the outside of a cold drink or another cold surface. In this activity, students will prepare a sample of humid air since...

An experiment that demonstrates why there are clouds in the sky. Start with air, invisible water vapor, particles we call condensation nuclei, and air pressure...the cloud comes later!

Use this site to find out how humidity works and perform some activities related to humidity.

Explains how dew point is used to show the amount of moisture in the air. Gives an activity for measuring the dew point at home.

In this hands-on activity, students experiment to discover how moisture, pressure, temperature, and condensation nuclei play a role in cloud formation.

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make...
