This lab activity examines the concepts of interpolation and extrapolation in data analysis. Students will study how to determine the number of pennies in a sealed container using their understanding of mass and graphing techniques. The exercise involves making estimations based on provided data points, and students will need to answer follow-up questions, seeking help as needed. Additionally, a bonus question provides an opportunity for extra credit by exploring extrapolated data points that extend beyond the known range.

1/24 • Compare and contrast the terms interpolate and extrapolate (in preparation for lab) • Penny Lab • Use your knowledge of mass and graphing to determine how many pennies are in a sealed container • Using your best effort, answer the follow-up questions • Ask for help on a questions when needed • Bonus question = extra credit
Extrapolated • The extrapolated point is one that lies outside the known data range and is shown by using a dotted line to extend your line.
Interpolated • An interpolated point is one that lies within the known data range but was not measured. • Knowing one of the two values allows you to interpolate the other value by following across (or up) to your line and then down (or across) to your unknown data.
