Experiment to simulate the radioactive decay of U-235

• victorhugo
In summary, the conversation was discussing a high-school homework assignment involving an experiment similar to radioactive decay. The experiment involved dropping pins into a box, removing the upside down ones to represent decay, and repeating the process until there were no pins left. The conversation also touched on the accuracy of the experiment, potential improvements, and the importance of valid and reliable results. The summary concludes with the suggestion to repeat the experiment and graph the average results.

Basic high-school homework. I mostly just want feedback on my answers and advice :)

The experiment was to:
Drop pins into a box. Pick out the one's upside down and count them and these are the ones that underwent decay.
Get the ones that weren't upside down and throw them into the box again, then repeat the process until there are not pins left.

This seems to be very similar how half life works, but I just need help in answering these questions:

1) 3 aspects that make this experiment accurate in showing the radioactive decay of U-235

-The process of removing the ones that were upside down is identical to what happens when an U-235 atom decays and stops
-Uses "chance/probability" which would be very close to 50/50, just like in radioactive decay
-Doing the experiment until there is no pins left is the same as when a sample of U undegoes complete decay.

2) Identify two improvements to this process

3) Draw a table so that the results are valid and reliable.
>Valid and Reliable are important terms to this, but I'm sure not sure how either than just repeating...

>Does this mean I should repeat the experiment, drawing various tables and average them out?
