Friday: Testing Everywhere

Rocket folds a paper airplane and tosses it. It nose dives. "Too heavy in front!" he laughs.

He refolds it and flies it again. Raven writes the change in her notebook.

"What do you notice?" she asks. "You test things all the time."

Nova hovers by the notebook. "Look at your notes," she says. "Do testers and model builders share a habit?"

People test things every day

Cooks test a recipe and change it. Builders test a bridge model with weights.

Model builders test too. They check how often a model is right.

The habit is the same. Try it, check it, fix it, try again.

A mistake is not the end. It is the next clue.
