Science & Society

Trade-offs, unexpected effects and science careers.

What your child practices

Practices weighing the costs and benefits of technologies, spotting unforeseen consequences, taking action on science issues, and linking science to careers and hobbies.

New York State Learning Standards learning standard: HS-ETS1-3; HS-ESS3-2 · weighing the costs, benefits and trade-offs of technologies and energy solutions

How we explain it

Children can open this short lesson before they practice.

  1. Every technology has costs and benefits, and sometimes unforeseen consequences.
  2. The best solution weighs people, money and the environment, not just cost.
  3. Science is used in many careers and hobbies, such as farming, cooking and engineering.

Example: A cheap solution pollutes a river. Is it likely the best overall? It costs little money. But it harms the environment. Answer: no
