Engineering Constraints and Criteria.

๐ŸŽฏ Your mission

Run the experiment. Find out what really happens.

โšก The twist

Nature loves to surprise the careful watcher.

๐Ÿคฏ

Mind = Blown

๐Ÿ”ฌ The more you look, the more nature shows you.

๐Ÿ”ฎ

Make a hypothesis first

Before you start: write down what you think will happen, and why.

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

  • constraint
  • criteria
  • test

Materials Needed

  • scissors
  • straws
  • paper clips

Safety First

  • Adult supervision recommended.

Steps

Step 1 โ€” Read

Read about Waves and write down three key facts.

Step 2 โ€” Do

Conduct a design challenge: build a car powered only by a balloon. Measure how far it travels and iterate on your design at least twice.

Step 3 โ€” Observe

Watch carefully for any changes and note the time.

Step 4 โ€” Record

Create a data table to organize your measurements.
