Present Your Findings Make a graph of the data collected.
Label the x-axis as time.
Label the y-axis as the number of undecayed atoms.
Be sure to title the graph.
Turn the graph into your teacher.
Write a summary paragraph discussing this experiment and the results. Use the following questions to help guide the content of your paragraph.
What was your hypothesis? According to your data, do you think your hypothesis was correct?
What is a half-life?
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?)
Do you think the shape of the curve on your graph would change if you increased the half-life to 20 seconds? What does this reveal about radioactive decay?
Do you think the shape of the curve on your graph would change if you started with a smaller sample, say 50 atoms (pennies)? What does this reveal about radioactive decay?

It is much safer to be feared than loved, when, of the two, either must be dispensed with. . among the wonderful deeds of hannibal this one is enumerated: that having led an enormous army, composed of many various races of men, to fight in foreign lands, no dissensions arose either among them or against the prince, whether in his bad or in his good fortune. this arose from nothing else than his inhuman cruelty, which, with his boundless valour, made him revered and terrible in the sight of his soldiers, but without that cruelty, his other virtues were not sufficient to produce this effect. –the prince, niccolò machiavelli what kind of reasoning does machiavelli use in this excerpt? he uses inductive reasoning because he offers statistics to prove his claim. he uses inductive reasoning because he observes a pattern and proves a conclusion. he uses deductive reasoning because he relies on scientific experiments to prove a conclusion. he uses deductive reasoning because he introduces a conclusion and proves it with evidence.
