Chemistry with a Concience

Lesson 00 – Chemistry with a Conscience Overview

This document provides an overview of the unit along with a lesson sequence guide.

Lesson 01 – Writing the Principles: Lab Activity

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.

Lesson 02 – 12 Principle Match Up

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.

Lesson 03 – Sustainability Bingo

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.

Lesson 04 – The Story of Cosmetics Video Assessment

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.

Lesson 05 – Is It Easy Being Green?

Introduce the green chemistry shampoo challenge through an interactive ‘game show’ activity.

Lesson 06 – Cookie Equations

Students use cookies to help them understand that chemical equations must be balanced. They manipulate elements and form compounds represented by cookie parts.

Lesson 07 – The Heat is On: Lab 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.

Lesson 08 – pH Neutral: Lab Activity

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.

Lesson 09 – Orb-It

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.

Lesson 10 – Solvent Snapshot

Using International Safety cards, students analyze the toxicity of a variety of solvents they could use in the shampoo making process.

Lesson 11 – Shampoozled: Lab Activity

Students create a basic soap. During this process they monitor and maintain a set temperature range.

Lesson 12 – Shampoozled 2: Lab Activity

Reviewing the pH Neutral lesson, students strive to create a pH balanced shampoo and experiment with green emulsifiers.

Lesson 13 – In a Lather: Lab Activity

Students test different variables to see if they impact the effectiveness of the shampoo. And, they answer the question, “Does the lather matter?”

Lesson 14 – SLS Today

After viewing a Today Show segment, students evaluate the safety of sodium lauryl sulfate in their shampoos.

Lesson 15 – PPM: Lab Activity

In this optional lab activity from VWR Education, students practice standard serial dilution to better understand parts per million.

Lesson 16 – SLS Toxicology: Lab Activity

Students use lettuce or radish seeds to determine the toxicology of sodium lauryl sulfate.

Lesson 17 – Breaking the Tension: Lab Activity

Students observe the effect of surface tension in water and the dispersive force of detergents to understand how shampoos work.

Lesson 18 – Product Testing: Lab Activity

Students conduct and experiment to determine if the shampoo they created is effective in cleaning hair.

Lesson 19 – E-Factor

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.

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.

Lesson 21 – Puzzler

Students create puzzles analyzing their research on renewable and non-renewable packaging materials.

Lesson 22 – Packed Up Properties: Lab Activity

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.

Lesson 23 – Water Waste: Lab Activity

Students test various waste streams likely to come from household products and evaluate the environmental impacts of those wastes.

Lesson 24 – The Green Zine

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.

Supplemental – DIY Cosmetics Recipes

Dive deeper into the world of cosmetics chemistry with these recipes for a variety of personal care products.

Supplemental – Personal Care Product Inventory

Short activator to get students thinking about the role personal care products play in their lives.
