The Engineering Design Process

Lab Brief #4

🎯 Your mission

Predict it first. Then prove yourself right (or wrong).

⚡ The twist

The first design always fails. That's the point.

What you'll learn

Engineers use the design process to solve problems: identify the problem, research, brainstorm solutions, build a prototype, test it, evaluate results, and improve the design.

Key words

prototype
An early model built to test how something will work.
design
A plan you make to build or test something on purpose.

Make a hypothesis first

Guess: what's the weakest part of this build?

Say your guess out loud — then find out if you were right.

Get ready

🧰 What you need

tape
straws
paper clips

⚠️ Safety first

Have an adult check your set-up before you start, and tidy everything away afterwards.

Step 1 of 4 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 4 · Do

Design a device that can protect an egg from a 2-meter drop. You may use paper, tape, straws, and cotton. Test it and improve your design.

Step 3 of 4 · Observe

Observe what happens and describe it in detail.

Step 4 of 4 · Record

Record your observations in your science journal with measurements and descriptions.

Mind = blown

🛠️ The first computer bug was a literal moth stuck inside a machine in 1947.

Nice work!

You got 0 of 3 right.
