Exploring Exponential Decay

Activity Overview

Students will work in pairs and conduct an experiment with M&M's where they start with a cupful and continue to decrease the n umber of M&M's in their cup.

Before the Activity

The teacher will provide each pair of students with a lab sheet and explain the directions.

During the Activity

Students are to follow the directions on the attached document. When done, students will have their graph displayed on their calculators. The teacher will capture their screens for sharing and discussion.

After the Activity

Students can use a natural log transformation on their data to find an exponential model in base e for the decay of the M&M's.
