Grade 10 | Science Module Answer Key

The answer key stayed in the red folder, untouched, right where it belonged.

For two hours, they worked through every problem Leo had flagged. When they got to question 17—the one about acceleration and the rolling bowling ball—Mr. Alonzo slid a blank sheet of paper toward him.

Bottom drawer. Red folder.

He stood there for a long time. The answer key felt heavy in his hand. He thought about the shop, the grease under his fingernails, the way his mother fell asleep on the couch with her reading glasses on. He thought about Mr. Alonzo, who always called him “Mr. Reyes” instead of just “Leo,” who never once marked him late even when he came in ten minutes after the bell.

Mr. Alonzo didn’t mention the folder. He just pulled out two chairs, set a fresh pot of coffee on his desk, and laid out Unit 3 from scratch. “Force is a push or a pull,” he began, drawing arrows on a whiteboard. “And momentum isn’t magic. It’s mass times velocity. You fix cars, Leo. You know more about force than half this class.” grade 10 science module answer key

So when his friend Mari handed him a folded slip of paper in the cafeteria— “Alonzo’s desk, bottom drawer, red folder” —Leo took it.

“I just need the answer key,” he whispered to no one. The answer key stayed in the red folder,

“Don’t look at the back of the module,” he said. “That’s the answer key. But real knowledge doesn’t live in the back. It lives here.” He tapped Leo’s temple.
