Engineering and Design.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
The first design always fails. That's the point.
Mind = Blown
🛠️ The first computer bug was a literal moth stuck inside a machine in 1947.
Make a hypothesis first
Guess: what's the weakest part of this build?
What You'll Learn
Models help scientists represent complex systems. Physical models (like a globe), mathematical models (like equations), and computer models all simplify reality to make it easier to study.
Key Words
- control
- data
Materials Needed
- pennies
- plastic wrap
- cardboard
- tape
Safety First
- Handle glass items carefully to avoid breakage.
Steps
Review the background information on Engineering and Design before starting.
Build a simple seismograph using a pen, cup, string, and paper. Shake the table and record the marks. Can you detect bigger vs. smaller shakes?
Look for patterns in your observations.
Make a graph or chart showing your results.

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?”
