How will you know if it’s strong? Let’s use a model to see if our engineering solution will work.

Agricultural engineers use model flowers to test their designs so that real plants are not injured.

You can’t bring a river into class, build a bridge over it, and cross it to test how strong it is. So what CAN you use for models?
