Engineering Constraints and Criteria

๐ŸงชLab Brief #16

Engineering and Design.

๐ŸŽฏ Your mission

Push the limits. See what changes.

โšก The twist

Every solution creates a new problem. That's good โ€” that's the next project.

๐Ÿคฏ

Mind = Blown

๐Ÿš€ The Saturn V rocket burned 20 tons of fuel per second at liftoff.

๐Ÿ”ฎ

Make a hypothesis first

Predict: which design will hold the most weight?

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

Steps

Step 1 โ€” Read

Read about Engineering and Design 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.

Where you see this in real life

Your phone, your bike, your shoes โ€” all designed with this idea.

Stretch Challenge

Try this in real life this week.

Build something โ€” anything โ€” out of stuff in your recycling bin.

๐Ÿ‘จโ€๐Ÿ‘ฉโ€๐Ÿ‘ง

For the dinner table

โ€œWhat's something around the house you'd redesign โ€” and how?โ€
