Freshwater Habitats

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 lesson, students insert temperature probes into different types of soil at varying depths. Students complete a data chart and construct a related graph...

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 takes to...

Students discover how clouds form and how air pressure and air temperature affect their formation. The lesson plan 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...

Oceans absorb half of the carbon dioxide and 80 percent of the greenhouse gases released into the atmosphere. Scholars learn how and why the oceans store heat more effectively than land and how they help mitigate global warming. Pupils...

Middle schoolers 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.
