Students make their own glue in an over-the-top lab procedure. Once the activity is complete, students are challenged to improve the given procedure during which they draw out the 12 Principles of Green Chemistry in the process.
Students use the example of text messages to understand different uses of language, break down scientific terminology and explain the 12 Principles of Green Chemistry in simple language.
Reinforce the 12 Principles of Green Chemistry through a bingo game using simplified versions of each principle and examples of the principles lived out in daily student life.
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.
Introduce the green chemistry shampoo challenge through an interactive ‘game show’ activity.
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 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.
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.
Using International Safety cards, students analyze the toxicity of a variety of solvents they could use in the shampoo making process.
Students create a basic soap. During this process they monitor and maintain a set temperature range.
Reviewing the pH Neutral lesson, students strive to create a pH balanced shampoo and experiment with green emulsifiers.
Students test different variables to see if they impact the effectiveness of the shampoo. And, they answer the question, “Does the lather matter?”
After viewing a Today Show segment, students evaluate the safety of sodium lauryl sulfate in their shampoos.
In this optional lab activity from VWR Education, students practice standard serial dilution to better understand parts per million.
Students use lettuce or radish seeds to determine the toxicology of sodium lauryl sulfate.
Students observe the effect of surface tension in water and the dispersive force of detergents to understand how shampoos work.
Students conduct and experiment to determine if the shampoo they created is effective in cleaning hair.
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 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.
Students create puzzles analyzing their research on renewable and non-renewable packaging materials.
Students use the properties of matter and the 12 Principles of Green chemistry to test various packaging materials and determine the most green and effective choice for their shampoo.
Students test various waste streams likely to come from household products and evaluate the environmental impacts of those wastes.
Culminating activity. Students create a magazine test, Goodguide.com web page, and an art campaign to analyze their use of the 12 Principles of Green Chemistry and to promote their implementation.
Dive deeper into the world of cosmetics chemistry with these recipes for a variety of personal care products.
Short activator to get students thinking about the role personal care products play in their lives.
