Half Life Experiment
Half Life Experiment
My hypothesis would be that after each shaking about half of the remaining candies would be logo-up and half of them logo-down. That's why the shaking represents a "half-life". half-life || total time (sec) || # of undecayed atoms || # of decayed atoms

According to my data no my hypothesis was not correct because the number of candies removed after each shaking cannot be the same. It will always be approximately half of what it was on the previous shaking, because the starting number for each shaking will be only about half of what it was the previous time.
Half Life is the time taken for the radioactivity of a specified isotope to fall to half its original value.
When does a radioactive sample emit the largest number of decay particles? Why is this information important? (How can it be applied in our world today?) :
When it is young. A recent incident that illustrates the importance of this is, that although a large amount of radioactive material from the Japanese reactors went into the
Pacific Ocean about a year ago, most of the harmful radiation in it will be gone by the time that water gets to the USA.
Do you think the shape of the curve on your graph would change if you increased the half-life to 20 seconds? (You should try this experiment if you have time.) What does this reveal about radioactive decay? :
Whether the shape of the curve would change if you increased the
half-life
