Curated OER
Evaporation of Alcohol and Water
Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.
Curated OER
Chemistry Module
Students build metal atomic models using styrofoam. In this chemistry lesson, students identify the different unique properties of metals. They explain how metal atoms bond.

Atomic Structure
Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...
Curated OER
Exothermic vs. Endothermic
The PowerPoint opens with video footage of the decomposition of nitrogen triiodide and then explains it with diagrams. Graphs of exothermic and endothermic reactions are exhibited, as well as one for the effect of a catalyst on reaction...
Curated OER
Oxidation and Salt
Students study the reaction on iron in water, air, and sodium chloride. They create a situation that shows this process and gives them the opportunity to hypothesize what, why, and how. They keep records and do an oral and written ...
Cornell University
Bacteria Take Over and Down
Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Solution Concentrations
What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original solution.
Curated OER
Water and Polymers
Students conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...
