What are stronger materials?

Stronger materials are ones that can hold up better when something tries to push or pull them apart.

Imagine you're building a tower out of blocks, if you use big, heavy blocks, the tower is harder to knock over than if you used tiny, light ones. That’s like how stronger materials work in real life.

Think about your favorite toy, maybe it's a robot that can take punches from other robots. If the robot is made of hard plastic, it might not get broken easily. But if it's made of soft clay, it might squish and break more quickly. The hard plastic is like a stronger material because it resists being pushed or pulled apart.

Your backpack is usually made of fabric, that’s pretty strong, but not the strongest. If you put a lot of books in it, it might tear. But if your backpack was made of something like metal, it would be much harder to tear. That's why stronger materials are used for things that need to handle more force, like bridges or cars!
