Lesson 20 – In Your Bathroom
Students collect data on ingredients found in products brought from home and investigate the substances used to make these products. They use this data to practice choosing data display methods.

In this activity from Professor Irv Levy at Gordon College, students manipulate m&m candy pieces to calculate Environmental Impact Factor (E-Factor) and relate it to chemical manufacturing.
Students conduct and experiment to determine if the shampoo they created is effective in cleaning hair.
Students observe the effect of surface tension in water and the dispersive force of detergents to understand how shampoos work.
Students use lettuce or radish seeds to determine the toxicology of sodium lauryl sulfate.
In this optional lab activity from VWR Education, students practice standard serial dilution to better understand parts per million.
After viewing a Today Show segment, students evaluate the safety of sodium lauryl sulfate in their shampoos.
Students test different variables to see if they impact the effectiveness of the shampoo. And, they answer the question, “Does the lather matter?”
Reviewing the pH Neutral lesson, students strive to create a pH balanced shampoo and experiment with green emulsifiers.
Students create a basic soap. During this process they monitor and maintain a set temperature range.
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.
