Challenge
Domino Chain Reaction Demo
Objective: Use falling dominos to illustrate the idea of a nuclear chain reaction.
Challenge: Arrange 10–15 dominos standing on end in a line or circle. Tip the first domino and observe the chain reaction – each falling domino knocks down the next. Note how the reaction propagates and how fast the sequence proceeds. You have recreated a simple “chain reaction” where one event triggers the next.
Extra Challenge: Modify your setup to explore control of the reaction. For example, leave a small gap partway through the line or place an obstacle (like a small block) to stop the dominos. Try adding a second branch of dominos so one falling domino splits the reaction in two directions. Observe what happens if one branch is blocked while the other continues. Explain how inserting or removing blockers in your domino line is analogous to how control rods regulate a nuclear reactor.
Answer: Challenge demonstration only – observe and discuss your results.
