Making It Work for Someone Else

🧪Lab Brief #7

Engineering and Design.

🎯 Your mission

Set it up. Test it. Be amazed.

⚡ The twist

Every solution creates a new problem. That's good — that's the next project.

🤯

Mind = Blown

🚀 The Saturn V rocket burned 20 tons of fuel per second at liftoff.

🔮

Make a hypothesis first

Predict: which design will hold the most weight?

What You'll Learn

A design is only good if the person who has to use it can. Testing your build with a real user almost always finds something you never noticed, because you already knew how it was supposed to work.

Key Words

Tap a word to see its definition.

Materials Needed

  • card
  • tape
  • scissors
  • notebook

Safety First

  • Use scissors carefully and cut away from your fingers.

Steps

Step 1Read

Read the explanation above and note the two key terms before you start.

Step 2Do

Step 3Observe

Record what actually happened, including anything that did not match what you expected.

Step 4Record

Write a conclusion that answers the question this lesson opened with, and state your uncertainty.
