Using International Safety cards, students analyze the toxicity of a variety of solvents they could use in the shampoo making process.
Using GoodGuide.com as a basis for data, students use a graphic organizer, the orb, to make determine which shampoo is the “greenest”. There are product sheets with background information on three separate shampoo brands.
Students observe, measure, and record what happens as varying amounts of an acidic solution is added to a basic solution to obtain neutralization. The goal is to create a pH balanced shampoo.
While using sodium hydroxide to create the base of their shampoos, students observe an exothermic reaction, measure the amount of heat, create a temperature over time graph showing their results, and determine ambient temperature strategies to use in the lab.
Students use cookies to help them understand that chemical equations must be balanced. They manipulate elements and form compounds represented by cookie parts.
Introduce the green chemistry shampoo challenge through an interactive ‘game show’ activity.
Students use critical thinking skills to analyze a video highlighting how cosmetics are made and regulated. Student will distinguish between fact and opinion within the video.
