Radioactive Decay Simulation with Scratch

The video tutorial explains a radioactive decay simulation created in Scratch. It covers how the simulation works, focusing on the Scratch code that simulates the decay process by using random numbers to determine when isotopes decay. The tutorial also demonstrates how to adjust the probability of decay and observe the effects on the simulation. Additionally, it describes the use of sprites and costumes to visually represent isotopes and the decay process.

What happens when you click the green flag in the simulation?

• The isotopes immediately decay.

• The simulation ends.

• The stage fills with 100 parent isotopes.

• The stage fills with 100 daughter isotopes.

How is the probability of decay determined in the simulation?

• By the number of isotopes present.

• By the color of the isotopes.

• By selecting a random number and comparing it to a set threshold.

• By the size of the isotopes.

What is the effect of changing the random number range to 1 to 10?

• It simulates a 10-sided die roll.

• It decreases the probability of decay.

• It stops the simulation.

• It increases the number of isotopes.

What does the 'next' button do in the simulation?

• It adds more isotopes to the stage.

• It changes the color of isotopes.

• It increments time and checks for isotope decay.

• It resets the simulation.

What are the two main sprites used in the Scratch program?

• One for isotopes and one for the next button.

• One for the background and one for the timer.

• One for the next button and one for the timer.

• One for isotopes and one for the background.
