Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we create a sustainable haircare product that effectively combines chemistry principles with environmental responsibility while considering consumer choices and measuring its effectiveness against traditional options?

Essential Questions

Supporting questions that break down major concepts.
  • What are the chemical principles behind the ingredients used in sustainable haircare products?
  • How can we measure the effectiveness of eco-friendly shampoos compared to traditional shampoos?
  • In what ways can we reduce the environmental impact of haircare products during the production, use, and disposal phases?
  • What role do consumer choices play in the sustainability of haircare products?
  • How can understanding matter and chemical reactions help us create a safer and more effective shampoo?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Identify and explain the chemical principles behind the ingredients used in sustainable haircare products.
  • Design and conduct experiments to measure the effectiveness of eco-friendly shampoos against traditional shampoos.
  • Analyze the environmental impact of haircare products during production, use, and disposal phases.
  • Evaluate consumer choices and their implications on sustainability in haircare.

Next Generation Science Standards

HS-PS1-1
Primary
Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.Reason: This standard directly relates to analyzing the chemical reactions involved in creating sustainable haircare products.
HS-PS1-5
Secondary
Use mathematical representations to support the claim that atoms, and the mass of atoms, are conserved in chemical reactions.Reason: This standard supports the understanding of matter conservation in the formulation of shampoo ingredients.
HS-ESS3-1
Secondary
Construct an argument supported by evidence to support the claim that humans can make choices to protect Earth’s resources and its capacity for sustaining life on the planet.Reason: This standard aligns with addressing environmental responsibility in the project.

Entry Events

Events that will be used to introduce the project to students

Nature vs. Science: The Great Shampoo Debate

Introduce students to a debate format where they must argue for or against conventional versus eco-friendly haircare products. This forces them to explore the chemistry behind both options and think critically about sustainability, consumer choices, and the environmental impact of the beauty industry.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

Chemistry of Hair: Exploring Ingredients

In this activity, students will research various ingredients commonly found in haircare products and evaluate their chemical properties and environmental impacts. This foundational knowledge will guide students in making informed choices for their sustainable haircare product design.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Start by listing common ingredients found in haircare products, such as sulfates, silicones, and natural oils.
2. Use online resources to research the chemical properties of each ingredient, focusing on their benefits and drawbacks.
3. Assess the environmental impact of these ingredients, considering factors like biodegradability and sourcing.
4. Compile your findings into a report that summarizes the properties and impacts of the ingredients.

Final Product

What students will submit as the final product of the activityA comprehensive report detailing the chemical properties and environmental impacts of various haircare ingredients.

Alignment

How this activity aligns with the learning objectives & standardsThis activity aligns with the standards related to understanding matter and its properties, which is essential for designing a product.
Activity 2

Sustainable Solutions: Eco-Friendly Alternatives

Students will now research eco-friendly alternatives to harmful haircare ingredients and begin to formulate ideas for their sustainable shampoo. This activity develops their ability to identify sustainable chemistry solutions.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Identify the harmful ingredients from your previous report.
2. Research potential eco-friendly alternatives for each harmful ingredient.
3. Evaluate the effectiveness of these alternatives in terms of haircare benefits.
4. Create a comparison chart summarizing the research on harmful ingredients and their eco-friendly alternatives.

Final Product

What students will submit as the final product of the activityA comparison chart that lists harmful ingredients alongside their sustainable alternatives and effectiveness.

Alignment

How this activity aligns with the learning objectives & standardsThis activity aligns with identifying and evaluating substances based on their properties, which supports the overall design of their product.
Activity 3

Design Your Shampoo: Formulation Planning

Students will apply their knowledge of chemistry and sustainability to design a formulation of their eco-friendly shampoo. They will utilize their research to choose appropriate ingredients and justify their selections based on chemical properties and environmental impacts.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Review your comparison chart and select the eco-friendly alternatives you wish to include in your shampoo.
2. Determine the proportions of each ingredient based on their chemical properties and desired shampoo characteristics (e.g. viscosity, lather).
3. Create a detailed formulation plan, describing each ingredient's role in the shampoo.
4. Develop a rationale explaining your ingredient choices and how they contribute to sustainability.

Final Product

What students will submit as the final product of the activityA shampoo formulation plan that outlines the ingredients, their roles, and a justification for their selection based on sustainability.

Alignment

How this activity aligns with the learning objectives & standardsThis activity directly aligns with the application of chemical principles in real-world contexts and reinforces the understanding of eco-sustainability.
