Experiment:
Problem: How will temperature or the type of solvent change the solubility of an
M&M?
Circle the one you are testing: TEMPERATURE or TYPE OF SOLVENT
If you are testing ‘temperature’ use hot tap water.
If you are testing ‘type of solvent’ use vinegar.
Make a prediction (like homework last night)
I will be setting up an experiment to see how _____________ affects the
solubility of the candy shell on an M&M.
I predict that changing the _____________ will affect the M&M shell by
causing it to wear away __________ compared to the one in regular water.
Making a hypothesis based on a prediction: In science we make a hypothesis
based on what we think will happen along with what we know about the topic.
I think that the M&M in ______________________________________
will_____________________________________________________because
______________________________________________________________
______________________________________________________________
______________________________________________________________
_____________________________________________________________.
Procedure:
1. Place one M&M in room temperature water and one M&M in what you are
testing from above (temperature or type of solvent)
2. Make observations that include how the outside of the M&M looks like every
30 seconds for five minutes. Write your observation in the table below.

Post-Activity Questions: Remember to use complete sentences and details.
1. How does temperature affect solubility? Need to talk about thermal energy and
particles in your answer.

2. Identify the solute(s) and solvent in each solution. Underline the solute and
circle the solvents.
a. Ocean Water: Salt and Water
b. Antifreeze: Water and ethylene glycol
c. Soda Pop: syrup, water and CO2 gas
d. Kool-Aid: powder, sugar and water
e. Lemonade: water, lemon juice, and sugar
3.Why would a candy shell barely dissolve in the sugar solution? Need to talk about
particles, what a solution is (including solute and solvent).

barely sweet Kool-Aid? Give a reason for your answer.

5.Mrs. Schroeder’s children always complain that the Kool-Aid that she makes is
not sweet enough. Explain how she can make it sweeter using the words solute,
solvent, solution, and concentration.

6.Mrs. Schroeder makes the Kool-Aid sweeter for her children, but after she is
done she notices that the sugar is just collecting on the bottom of the container.
Explain what she has done using the words solute, solvent, solution, concentration,
and saturation.
