The Big Burp: Where's the Proof.
Young scholars explore the Cambrian explosion and Paleocene extinction events. In this climate change lesson, students read articles to link evidence they find to extinction and climate change. Links to the articles are included in the...
Curated OER
Weathering and Erosion
Students investigate how changes occur on the surface of the earth through erosion and glaciation. They observe what happens to salt and iron after they interact with water and vinegar, and analyze what occurs when water is sprinkled on...
Curated OER
Changing in Ohio
Fifth graders familiarize themselves with more abstract chemical/physical changes that are directly connected to Ohio. They use their knowledge of chemical and physical changes to distinguish these two, even though they may not be...
Curated OER
Blast Off
In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...
