Overview:

In this lesson, students will design an experiment to see if temperature affects the amount of dissolving of the sugar coating of an M&M.

Students will be able to identify and control variables to design an experiment to see whether the temperature of a solvent affects the speed at which a solute dissolves. Students will be able to explain, on the molecular level, why increasing temperature increases the rate of dissolving.

Content Standard(s):
Science
SC2015 (2015)
Grade: 8
Physical Science
2 ) Plan and carry out investigations to generate evidence supporting the claim that one pure substance can be distinguished from another based on characteristic properties.


Alabama Alternate Achievement Standards
AAS Standard:
SCI.AAS.8.2- Identify characteristics that distinguish one pure substance from another (e.g., color, hardness, flammability).


Science
SC2015 (2015)
Grade: 8
Physical Science
4 ) Design and conduct an experiment to determine changes in particle motion, temperature, and state of a pure substance when thermal energy is added to or removed from a system.


Alabama Alternate Achievement Standards
AAS Standard:
SCI.AAS.8.4- Recognize that changes in temperature can cause changes in the state of matter of a substance; recognize that these changes are a result of changes in particle motion.
