Materials & Properties
📋 What it is
Every material has properties — strong, flexible, light, waterproof — and a maker picks the right one for the job.
🗣️ Coach says
A maker is a material matchmaker. Wood is strong and easy to cut; plastic is light and waterproof; metal is tough; foam is soft. Knowing what each material DOES lets you pick the right one so your project actually works.

Every material has a job. Match the property to the task.

What did the circuit say to the battery?
"You really give me a charge!"
😲 Whoa!
Engineers test materials to find their exact strength — some can hold thousands of times their own weight before breaking.
✅ Quick check: Why does a maker need to understand the properties of different materials?
Say your answer out loud first — then reveal.
So they can pick the right material for the job — strong where it needs strength, flexible or waterproof where needed — making the project actually work.
Matching material to purpose is fundamental engineering thinking.
