Science/Strand IV/Content Standard 1/High School
Benchmark 1
Analyze properties of common household and agricultural materials in terms of risk/benefit balance (SCI.IV.1.HS.1).

Benchmark Clarification

Common household and agricultural materials (bleaches, drain cleaners, detergents, lubricants, fertilizers, herbicides, and pesticides) have both benefits and risks. These risks and benefits may be evaluated using criteria such as: safety, human health, environment, politics (governmental), and economics.

Students will:

  • Evaluate the benefits of common household or agricultural materials by using a risk/benefit analysis that utilizes these criteria

Instructional Example

Benchmark Question: How do we describe the things around us?

Focus Question: What are the risks and benefits of using an everyday household product?

After a classroom discussion of risk/benefit analysis clarifying the criteria of safety, human health, environment, politics, and economics, students will work in small groups to research a common household product. Once they have completed their research, they will conduct a risk/benefit analysis to determine whether or not the product should be used. Each group will justify their position in a classroom presentation.

Constructing: (SCI.I.1.HS.4), (SCI.I.1.HS.5).

Reflecting: (SCI.II.1.HS.1), (SCI.II.1.HS.5), (SCI.II.1.HS.6).
