Intro to Half-Life PhET Lab (Radioactive Dating Game). Introduction: Dead things decay into simpler molecules. Radioactive particles decay. Is it the same kind of decay? What does it mean when a substance is radioactive? In this simulation, you will investigate the concept of half-life. Some handy vocabulary for you to. View Lab Report - half life lab from AL 1 at Bethel Park Hs. Intro to Half-Life PhET Lab (Radioactive Dating Game) Introduction: Dead things decay into simpler molecules. Radioactive particles decay. Why or why not? Further Investigation on half-life: Use the Half Life tab in the simulation to answer the following questions. Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
This preview shows page 1. Sign up to view the full content. Dead things decay into simpler molecules. Is it the same kind of decay? What does it mean when a substance is radioactive? In this simulation, you will investigate the concept of half-life. Pre-Lab Warm Up 1. How does carbon differ continue reading carbon and carbon?
Which number in the PTE block for carbon do isotopes affect? Double click on the JNLP tea cup icon on your desktop to enter the simulation. Take some time and play with the simulation.
Those atoms are radioactive! How cool is that?! Click on the Half Life tab in the top left corner of the simulation. What observation s do notice about the carbon atoms in the play area? Add 40 more carbon atoms to the play area. You should have a total of 50 carbon atoms.
If you add the two elements together in the pie chart, you can determine how many atoms are in the play area. Click the button once you have 50 check this out. This will start all carbon14 atoms off at the same point in time.
Use the pause and play buttons. Click the pause button with the graph gets close to 5 years. Take a screenshot of the pie chart and numbers for each isotope. Click the play button to continue the trial by repeating steps 1 and 2 at 10 and 15 years. Repeat the steps for data collection for Table 1 to complete two trials with atoms of carbon — Why or why not? Further Investigation on half-life: Use the Half Life tab in the simulation to answer the following questions.
Click the circle simulation to see its half-life graph. How would you determine the half-life of this unknown element?
Share this link with a friend: Il gioco della Datazione radiometrica. Click on the Dating Game tab simulation. What does it mean when a substance is radioactive? Describe the pattern you see between where an organism is found and which probe type you used to date the organism.
Write up a short procedure: Estimate the half-life of this element. Click on the Dating Game tab simulation. Example on how to use the Geiger counter. Make sure the circle next to carbon is checked b. Click and drag the Geiger counter, measures radioactive isotopes, so the end meets up with the house.

A number signifies there is a measurement and that the isotope will work to help us determine the age of the object. Try to get as close to the measurement as possible. It is OK if you cannot get the percent values to directly match. Type the number for t time in years in the Estimate age of House box. Make sure to type the number ONLY. Your simulation should have looked similar to this: Before checking the estimate ii.
After checking the estimate iii. Still confused on using the Geiger counter? Check out the movie tutorial on the assignment page.
You will use the same procedure to determine the age of the remaining objects. The age of some objects may require you to change the probe type. Record the age and probe type for each object in Table 3. Describe the pattern you see between where an organism is found and which probe type you used to date the organism. Use data from your table in your description.

Why does this pattern exist? Could Carbon be used to date a hammer suspected of being used in BC? You happen upon an antiques store and the clerk claims that he has a belt that was once worn by Alexander the Great, around BC. Could the belt be genuine? How did you arrive at your answer? This is the end of the preview.
