a Half Life
Exponential Equations: Overview of the Lesson
Get a Half Life
- The students modeled an
exponential decay situation in this activity.
- Students were given M&Ms
which they poured onto a plate
- They removed the M&Ms
that had the Ms facing upwards and counted the ones remaining on the
- They repeated the procedure
until they only had 1 or 2 M&Ms on their plates.
- The data was put into the
graphing calculators and they attempted to graph a line using a linear
- Then they did the same thing
for an exponential equation and saw a curve.
- This helped them see that
an exponential equation matched their data better than the line.
