The Ramp Race — What Rolls and What Slides?
{parent_name} and {child_name} build a simple ramp from a book propped on a cushion, then test different objects — a ball, a toy car, a block, a sock — to see what rolls, what slides, and what stays still. The agent guides observation of basic physics concepts through play.

What you'll need
A flat rigid surface (book, tray, board) propped on a cushion for a ramp. 5-6 household objects of different shapes.
How it works
- 1~30s
Let's start with the ball — the obvious one. Before your child puts it on the ramp, ask: 'What do you think will happen when we put the ball at the top?' Then let them place it and watch. After it rolls down, say 'It rolled! Why do you think it rolled?' Don't worry if they can't explain it — we're planting seeds. What happened?
Watch for: How does your child engage with the first ramp test?
- 2~30s
Now pick the object your child would least expect — the sock, or the spoon, or the block. Hold it up and ask the same question: 'Will this one roll?' This is where prediction gets interesting because the answer isn't obvious. Put it on the ramp and watch together. Ask your child: 'What happened? Was it the same as the ball?' Tell me how they reacts.
Watch for: Does your child predict differently for a non-round object? How do they handle a surprising result?
- 3~40s
Now here's the fun part. After testing at least four or five objects, ask your child to sort them into two groups: things that rolled, and things that didn't. You could put a piece of paper on each side — draw a happy ramp on one and a stopped ramp on the other, or just say 'rollers here, stoppers there.' Can your child sort them? And can they tell you why they go in each group?
Watch for: Can your child categorize objects by what happened on the ramp?
