Students identify the signs that a chemical reaction took place. In this chemistry lesson, students role play the movement of different molecules of matter. They classify matter according to their properties.

Students explain the Chatelier's Principle. In this pH lesson plan, students identify factors that resist changes in pH of the ocean and why the ocean is becoming more acidic.

Students define what a redox reaction is. In this chemistry lesson, students electroplate some wires in the lab. They research the application of electroplating in the real world.

Learners explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...
