Engineering and Design.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
Constraints make you more creative, not less.
Mind = Blown
🛠️ The first computer bug was a literal moth stuck inside a machine in 1947.
Make a hypothesis first
Before you test: how many tries until it works?
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
Tap a word to see its definition.
Materials Needed
- tape
Safety First
- Have an adult check your set-up before you start, and tidy everything away afterwards.
Steps
Look at the vocabulary words and write a definition for each in your own words.
Design and build a bridge from newspaper and tape that can hold a textbook. Test it and redesign to make it stronger.
Draw a detailed diagram of what you observe.
Write a conclusion: what did your results show? Did they match your prediction?

Question 1
1 of 3What is a constraint in engineering?
Where you see this in real life
Every bridge, building, and gadget you've ever used started with this.
Stretch Challenge
Try this in real life this week.
Find something that's broken at home and try to figure out *why* it broke.
For the dinner table
“What's something around the house you'd redesign — and how?”
