🎯 Stairwell Launch Lab

A ball bearing rolls down a ramp and launches horizontally. Your job: predict exactly where it lands and put the target there. You get one official drop, and your score depends on how close the mark is to the bullseye.

🧪 Lab table: launch the ball off a table. Measure the drop and where it lands, then work out the launch speed.
🪜 Stairwell: slide the ramp along the landing railing until it lines up over a step. There's a gap and a stair railing between the landing and the step, so hang the ramp out over the step and use the plumb bob. Then measure the new drop, calculate where the ball will land, and place the target on that step.
📏 Tape measure: turn it on, then drag from one dot to another (ramp end, plumb mark, step edge, landing marks, bullseye). Readings go in your notebook.

Level 1 · Guided

Every step is prompted and your numbers are checked.

Level 2 · Some help

A checklist and blank tables. Nothing is checked.

Level 3 · On your own

Just the equipment. You plan it all.

Each level uses a different ramp, so the launch speed changes. Hit the target to unlock the next level. Finish all three for your completion code.
