Using an auger, start-up soil scientists bore a core of soil. They examine the sample and record the temperature at three depths in the borehole. This is an attractive activity sheet that succinctly guides your earth science class...

Students investigate soil temperatures. In this graphing and earth science instructional activity, students insert temperature probes into different types of soil at varying depths. Students complete a data chart and construct a related...

Help your class come up with a procedure for comparing the dissolving rates of colored candy coating in different temperatures of water. If you are placing importance on controlled variables with your class, make sure that they use equal...

Learners take a look at the local newspaper and focus on the weather section. They get into small groups, and each one looks at the same map, but of a different part of the country. They must prepare a presentation that shows how...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Does a single-celled organism know more about the history of our planet than we do? A video explains how single-celled organisms manage to build a house and hold the secrets to the weather. They contain the information about the changes...

Students discover how clouds form and how air pressure and air temperature affect their formation. The instructional activity is delivered in the story of Mike Breezy, Air Detective, who tries to solve The Cloud Case.

Actual stream water is analyzed in this environmental science activity. Participants measure water temperature and pH, and then survey the macroinvertebrates living in their samples. The data worksheet, troubleshooting tips, and...

Students identify and count Macroinvertebrates at a Hydrology website.  In this macroinvertebrates lesson students collect, sort and identify Macroinvertebrates.

Learners examine the influences of water and mulch on soil temperature.  In this investigative activity students complete a soil experiment.
