The hypothesis is that as the distance between the dominoes is increased, the speed of their toppling decreases.

You will arrange 100 domino tiles in a row, measure the distance between them, and time how long it takes for them to topple over.

You will need 100 domino tiles, a measuring tape, a ruler, a stopwatch, and a flat floor.

The results showed that the speed of the tiles declined when the gap was increased from 10mm to 15mm. As the distance of the gap increased from 15mm to 30mm, the speed of the tiles increased. Beyond a gap distance of 30mm, the speed of the tiles continued to decline.

This science project is interesting because it demonstrates the domino effect, which is a chain reaction of events that can be triggered by a single action.

Variations: What would happen if the science fair project was repeated by using different sizes of domino blocks or Lego blocks? Try to repeat the science fair project by arranging 200 tiles or 300 tiles and measuring the speeds again.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
