Engineering and Design.
🎯 Your mission
Understand the idea. Then look for it everywhere.
⚡ 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
- design
- constraint
Steps
Read about Engineering and Design and write down three key facts.
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.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
