M&M Lab Procedures and Concepts

The video tutorial guides students through a Half-Life M&M lab, starting with preparation steps, including downloading the lab guide and completing pre-lab questions. The instructor demonstrates two trials where M&Ms are used to simulate radioactive decay, with students required to count and record results. The video concludes with instructions on data analysis, graphing, and completing a post-lab write-up.

What should students do before starting the lab?

• Watch the entire video

• Download the lab guide and complete pre-lab questions

• Prepare a presentation

• Read a textbook chapter

How many M&Ms are initially counted for the lab?

• 50

What is the purpose of shaking the M&Ms in the cup?

• To mix the colors

• To count them again

• To melt the chocolate

• To check for defects

• To count faster

How many trials are conducted in the lab?

• One

• Two

• Three

• Four

What should be done after completing both trials?

• Start a new experiment

• Throw away the M&Ms

• Write a report

• Calculate the average and graph the results

What is the final step in the lab process?

• Complete the post-lab write-up

• Submit the lab guide

• Discuss with classmates

• Watch another video
