Earthquake, Earthquake, Read All About It!
Students utilize the U.S. Geological Service web site. They research the various types of scales used to measure earthquakes and classify different situations on the scale. They write a story about a town that has just experienced a quake.

pH and Red Cabbage Juice
Students review properties of materials and define what pH tells them about matter. In this pH levels instructional activity, students determine whether materials are acids or bases using indicator substances.
Curated OER
Acid Rain
Students understand the dynamics of acid rain and its impact on the living and non-living environment. They hypothesize how acid rain affects water pH levels in two lake systems with differing watershed features.
