If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

Eighth graders analyze physical change in mass. In this chemistry lesson, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with elements,...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

Pupils explain the importance of the five main biogeochemical cycles. In this chemistry lesson plan, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

In this stoichiometry worksheet, students calculate molar masses, empirical and molecular formulas to solve 105 problems and short answer questions.

Learners demonstrate their understanding of a chemical process.  In this exploratory instructional activity students create a clay animation that shows how a specific type of chemical bond. 

Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...
