Radioactive dating worksheets

In uranium-lead dating, we see that two unstable uranium isotopes decay into stable lead isotopes. This quiz and corresponding worksheet will help you gauge your knowledge of radiometric dating methods and half-life through questions that test your understanding of what.

How can the absolute age of a rock be determined? By measuring the amount of the parent isotope to its newly formed daughter, and calculating the number of half-lives passed By comparing it to another reference of a similar ratio. By comparing the sample to a sample of a known age By comparing the half-life of the substance to the half-life of another substance. Print What is Radioactive Dating?

Now collect the coin that were tails and put them back in the bag. Close the bag and shake!

Repeat steps 4,5and 6 until you have run out of coins to put back in the bag Now take the data you have and draw a bar graph showing what happened to the size of your coin sample as went through all of the steps. Review all of your data. Write up your report by responding to the following questions: Explain what each coin represents.

Note how many times you had to toss the coins before they were all used up. Did you find a pattern? What does the bar graph show? If you repeated this experiment again, do you think you would get the same or different results? Explain why this experiment was useful in replicating a model of radioactive decay. Why were the coins a good way to model half-lives? Would the model work as well if we used coins?

Photoelectric smoke detectors optically detect particulate matter in the air To better understand the sources of the Earth's heat, scientists studied antineutrinos, elementary particles that, like their neutrino counterparts , only rarely interact with normal matter. Using the Kamioka Liquid-scintillator Antineutrino Detector KamLAND located under a mountain in Japan, they analyzed geoneutrinos — ones emitted by decaying radioactive materials within the Earth — over the course of more than seven years.

The specific amount of energy an antineutrino packs on the rare occasions one does collide with normal matter can tell scientists about what material emitted it in the first place — for instance, radioactive material from within the Earth, as opposed to in nuclear reactors. If one also knows how rarely such an antineutrino interacts with normal matter, one can then estimate how many antineutrinos are being emitted and how much energy they are carrying in total. The researchers found the decay of radioactive isotopes uranium and thorium together contributed 20 trillion watts to the amount of heat Earth radiates into space, about six times as much power as the United States consumes.

As huge as this value is, it only represents about half of the total heat leaving the planet.
