Domino Chain

This simulation lets students design and test domino runs. Click to place a piece, drag to reposition it, and click a domino to start a fall. Buttons add a curved row, push the first domino, stand everything up, remove the last piece or clear the table, and a slider sets the gap for added rows. Readouts show placed, fallen, wave speed and chain state. Teachers can explore spacing and cause and effect: find the largest gap that still passes the topple along, and relate it to height and angle.

• Click the table to place several dominoes in a line, then press Push first and watch the chain.
• Drag a domino farther from its neighbor until the chain stops, then read how many Fallen.
• Use Add curved row with a different Gap and compare the Wave speed readout.
• Press Stand all up after a failed run, move pieces closer, and try again.
• Use Remove last to undo a placement, or Clear table to design a new layout.

1. 1Explain how one falling domino transfers energy to the next.
2. 2Investigate how spacing affects whether a chain continues.
3. 3Measure and compare the speed of a toppling wave.
4. 4Revise a design after testing it, using the fallen count as evidence.
