4.3.3 Discover Analyze Geometric Sequences & Exponential Functions Discover 2 Investigation 2: Modeling Half-Life The ______________________of a material is the amount of time it takes for the amount of material to decrease to half the amount that existed at the beginning of the time period. Watch the video on page 3 of today’s lesson to observe the decaying process in action. Is it possible to predict the amount of a substance left after a given amount of time? Complete the Hands-On Activity on the next page to find out! Hands-On Activity: Half-Life Model You will need the follow household materials to complete this activity. 8.5" x 11" paper scissors ruler If you do not have a ruler at home, feel free to use the online, actual sized, ruler found on page 4 of today’s lesson,, but be sure to set it up for your CCA laptop's screen size (15 inches). You can model _________________ using a sheet of paper and scissors. The area of each piece of paper that remains after each cut represents the amount of a substance left at the end of each _____________ period.
