![]() Explore the Java applet Radioactive Dating Game. ![]() What type of reaction do Carbon -14 and Uranium- 238 undergo? Explain how you figured this out and write the reaction for each.Įxercise: Radioactive Dating Game activityġ. If you were a forensic scientist and found a dead buried body, could you use one of the isotopes in the simulation to figure out how long ago the person died? Explain.ĥ. If you can't get a reading on one object like the fish fossil what else can you try? Determine the approximate age of the fish fossil and explain what you did to estimate the fossil age.Ĥ. How does the percentage O Carbon-14 help you estimate the age?Ĭ. How do you decide which to use: Carbon-14 or Uranium-238?Ĩ8.2 % Probe Type b. Pretend you are a scientist and have a tool like the one on Dating Game tab: Uranium-238 a. What elements' isotopes are used to estimate how old something is? Why do scientists use more than one type? (Be specific, it is not just to get repeated results) Try all the tabs to figure out why there is more than one element used to estimate how old things might be.Ģ. Identify types of nuclear reaction used for dating include how elements change and balanced reaction.ĭirections: 1. Use the percent of an isotope measured in an object to estimate its age. Explain how radiometric dating works and why different elements are used for dating different objects. Goals: Students will be able to: Identify isotopes that are commonly used to determine how old matter might be. SOLVED: Exercise: Radioactive Dating Game activity
