The physical and chemical changes lab involves usage of chemicals and various lab equipment. This is a lab that is meant for students to learn how to use the lab equipment and to identify chemical and physical changes in chemistry. The techniques used in the procedures help students prep for the various labs that are typically performed in chemistry. There are post and pre lab questions and a conclusion so students can distinguish between chemical reactions and physical changes.

This is a fun way to teach experimental design or variables. The instructions are thorough and so is the rubric. They are to identify a product they like, let's say, Starbucks. They have to convince the audience that Starbucks is the best caffeinated drink company. They develop a hypothesis, experimental design, identity variables and fabricate data. They put this info in one slide or poster. Their peers can critique it and identify components of experimental design in their notebook. The creati

When students learn about acids and bases, tying it to ocean acidification can appeal to them. This lab is meant for students to see what happens to calcium carbonate based shelled organisms when exposed to too much acid. This lab is inquiry based and the instructor can front load how acids react with bases.
