Curated OER
Stoichiometry (gases and masses)
In this chemistry worksheet, students identify how many liters of oxygen can be consumed to form carbon dioxide. Then they identify how many liters of sulfur dioxide are produced if the gas is at STP.

Volcanos and the Atmosphere
In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...
Curated OER
Air Quality Trivia Time
Students identify and analyze what the Air Quality Index (AQI) is and how it works. They review ways that "unhealthy" or "hazardous" days could be prevented and draw and color something that they can do to help reduce air pollution....
Curated OER
Acid Rain
Learners perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.
Curated OER
Exothermic and Endothermic Reactions
Students observe demonstrations of exothermic and endothermic reactions and determine the changes that take place in a chemical reaction. Students observe four demonstrations showing entropy, attraction of molecules due to polarity,...
