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 plate.
  
• 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 equation.
  
• 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.
