Engineering Constraints and Criteria (Part 2)

What You'll Learn

Engineers must consider constraints (limitations like cost, time, and materials) and criteria (requirements the solution must meet) when designing solutions to problems.

Key Words

criteria
iteration
wavelength

Materials Needed

cups
aluminum foil

markers

Safety First

Wash hands after handling materials.
Be careful with scissors — ask an adult for help if needed.

Steps

Step 1 — Read
