Using Popcorn to Simulate Radioactive Decay
Full Name ____Daniel Menzies________ Block _C_ Date ____Oct. Life Popcorn Lab Purpose: To simulate radioactive decay and determine the half-life of Count out kernels of popcorn Put the kernels into the petri dish with a 5cm or. Radioactive dating is an important tool scientists use to do this. To find Repeat this process until all of the popcorn kernels have been removed from the box. 4. Popcorn starts out as unpopped “parent” kernels. Heating causes the kernels to begin popping, thereby starting your simulated “radioactive decay clock” and.

Generally, did the number of decay events kernels pointing to the tape increase, decrease, or stay the same? As the experiment continued the kernels pointing to the tape increased because there was less kernels moving them away from the tape.Radiometric Dating is Flawed!! Really?? How Old IS the Earth?
This represents the half-life. After 4 shakes which is close to 3.
Do the same comparison above for the 8cm tape and describe what you find. Do you think you would you get the same results if you repeated the experiment?
No, because there are a few mistakes that I have noted, which if I were to repeat the experiment I would definitely fix. Like as you take out a kernel you might accidently move another kernel to face the tape, without realizing it and not being that consistent with the shake pattern.
What results would you expect if the tape were 3 cm long? I would expect the experiment to take longer, and the half-life would also therefore increase. The longer your tape is the shorter the half-life is of the kernels, and if your tape is shorter it will take longer to complete the experiment and the half-life will be longer, the curve on the graph will also be steeper. The longer the half-life is the steeper the curve will be. Plot your values and draw a curve or best fit on a graph see below with the Parent nuclei 7.
Plot the values and draw a curve or best fit on the graph with one of the Daughter nuclei using an different color Label your graph and lines clearly. Generally, did the number of decay events kernels pointing to the tape increase, decrease, or stay the same?
There were less odds for the kernels to point to the tape because their were less kernels total.

This represents the half-life. Do the same comparison above for the 8cm tape and describe what you find. Do you think you would you get the same results if you repeated the experiment?
What results would you expect if the tape were 3 cm long? I do belive it supported the idea of half life decay because the amount of kernels accurately resembled the amount of parent cell because less and less were taken away but the total number of those taken away was getting bigger.
I do not believe it represented the experiment very well because I think the amount of kernels getting taken away with the 8cm and 5 cm tape were to similar.
