Answer
The experiment is designed to investigate the reaction times of two students. By dropping a ruler and measuring how quickly the second student can catch it, we can quantify their reaction time.

Answer
Student A holds a ruler vertically above Student B's hand, positioned between the thumb and index finger.
Student A releases the ruler without warning, simulating a real-world scenario.
Student B must react quickly to catch the falling ruler.
The distance the ruler falls before being caught is measured to quantify the reaction time.
Step 3
Repeat the experiment
