Bhopal - Covalent Bonding
Using the chemicals that leaked in the Bhopal gas tragedy of 1984, chemists examine covalent bonds. Provide for them the chemical reactions and have them draw Lewis diagrams for the molecules involved. That's about all there is to the...
Curated OER
Solids, Liquids, Gases
There are three states of matter, liquid, solid, and gas. Each are covered briefly in this very short presentation. The energy cycle is depicted in a chart and the states of matter are defined but this isn't a complete or...

If Hot Air Rises, Why Is it Cold in the Mountains?
Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.
Curated OER
States of Water
Students investigate the 3 states of matter. In this physical science "matter" lesson, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on changing...
Curated OER
Matter in Motion
Second graders examine matter, what it is and what the different states are. In this matter activity students view The Magic School Bus Meets Molly Cule and answer questions.

Gases
In this gases activity, students review the 3 states of matter, the types of molecular motion, and the characteristics of gases. This activity has 30 problems to solve.
Curated OER
Stoichiometry
In this stoichiometry instructional activity, students calculate balance the chemical equations and then calculate the moles needed to complete or activate the chemical reaction. Students also calculate the volume or grams needed for...
Curated OER
From Molecules to Mole Day Do's
Students recognize methods used to define the mole. After converting various quantities to the mole, students provide a context for understanding the usefulness of scientific notation and the mole.
Curated OER
The Great Gas Race
Fourth graders improve their understanding of Graham's Law by using properties of gases to evaluate the rate of effusion of two compounds as they vaporize. They engage in a lab which elevates their understanding of the properties of gases.
