Domino Derby Set up 25 equally spaced dominoes in a straight line. Use a meter stick to measure the total length of the row of dominoes, and record the length. Use a stopwatch to measure how long it takes the dominoes to fall. Predict what would happen if the distance between the dominoes changed. Test your prediction.
