Question: What factors affect the dissolving rate of the candy shell of an m&m?
Prediction:
___________________________________________________________________________
because _____________________________________________________________________________.
Procedure: Read the steps below, then obtain 3 pieces of M&M candy from your teacher. You will
need 3 pieces for each group member.
TEST 1: Place one piece of candy in your mouth and allow it to dissolve without
using your tongue or teeth to help! Record the time (in seconds) it takes for the
candy shell to dissolve.
TEST 2: Place another piece of candy in your mouth and allow it to dissolve using
only your tongue to move it around. Record the time (in seconds) it takes for the
candy shell to dissolve.
TEST 3: Place another piece of candy in your mouth and allow it to dissolve using
your tongue and teeth. Record the time (in seconds) it takes for the candy shell to dissolve.
4. In your solution, what were the solute and the solvent? Solute =__________ Solvent = ___________
5. In a paragraph, explain the results of your experiment in terms of dissolving rate or the time it takes
for a substance to dissolve. NEATLY print or use cursive to:
 Identify question / problem being tested
 Describe your procedure
 Identify the solute and the solvent
 Identify which test resulted in the fastest dissolving rate with data from the lab
 Explain why the test with the fastest dissolving rate did in fact have the fastest rate
