LAB REPORT FROM THE BELOW INSTRUCTIONS.

The lab report MUST have:

1. Introduction: What did you do in this experiment, and why? You should have a hypothesis, and it MUST be stated. It may be provided at the start or the end of this section. Give the background information that an intelligent but uninformed reader would need to understand why you are testing this hypothesis.
2. Procedures: In this section, write what you did.
3. Results: This section should be clear and organized. Data should be presented in a format that is understandable to the reader. This may be a chart, a graph, or a table - it will depend upon the nature of the data collected. Refer your reader to the table, chart, or graph, and make sure it is well-labeled. Include samples of any calculations you did.
4. Discussion: The discussion overall should be at least two paragraphs. Remind your reader of your hypothesis and discuss whether the results you obtained support or refute your hypothesis. Now interpret your data.

LAB:

DISCOVERY LAB Radiometric dating is the process of nding the age of rocks using the time it takes For the radioactive sub stances in the rock to decay. Have you ever wondered how scientists determine the age ofthe rocks? You can try this activity by gathering 100 MSCM candy pieces, a stopwatch, and a Styro foam cup. Put the MSdVI's (representing the rock) in a cup and record the total number of parent isotope {M&M's). Empty the contents of the cup on a table. Any \"M" of MScM's that is facedown will represent a decayed nucleus. Remove all the decayed nuclei and count the total number decayed {this represents the parent isotope]. Count the number of M&M's with the other side up {daughter isotope). Now you have gone through one halflife. Repeat the procedures every 2 minutes for ve trials or until all the M&M's are gone. Find the total number of halfLives the parent isotope went through. Find the age of the rock {MScM's} by calculating the parent-to- daughter ratio At every step nd the percent of the parent atom remaining in the rock. (Number ofhalflives x length ofhalf-life 2 age of the sample) In what ways is using the MScM's similar to radioactive decay
