Overview:

In this lesson, students will develop an understanding that whether and how much a substance dissolves (solubility) is a property of that substance. Students will be able to plan and carry out an investigation to compare the solubility of two substances.    

Students develop a test to compare how the candy coating from an M&M and a Skittle dissolve in water. Students put an M&M and a Skittle in the same amount of water at the same temperature at the same time. Students will also see that the inside of the Skittles dissolves but the inside of the M&M does not. Students see an animation to help explain why the inside of the Skittles dissolves but the inside of the M&M does not.

Content Standard(s):
Science
SC2015 (2015)
Grade: 2
1 ) Conduct an investigation to describe and classify various substances according to physical properties (e.g., milk being a liquid, not clear in color, assuming shape of its container, mixing with water; mineral oil being a liquid, clear in color, taking shape of its container, floating in water; a brick being a solid, not clear in color, rough in texture, not taking the shape of its container, sinking in water).

NAEP Framework
NAEP Statement::
E4.6: Some Earth materials have properties either in their present form or after design and modification that make them useful in solving human problems and enhancing the quality of life, as in the case of materials used for building or fuels used for heating and transportation.

NAEP Statement::
P4.1: Objects and substances have properties. Weight (mass) and volume are properties that can be measured using appropriate tools.*

NAEP Statement::
P4.3: Matter exists in several different states; the most common states are solid, liquid, and gas. Each state of matter has unique properties. For instance, gases are easily compressed while solids and liquids are not. The shape of a solid is independent of its container; liquids and gases take the shape of their containers.

  • Many types of matter can be either solid or liquid, depending on temperature.
Skills:
Students are able to:
  • Plan and conduct an investigation to produce data that is used to describe and classify substances according to physical properties.
Understanding:

Crosscutting Concepts: Scale, Proportion, and Quantity
Disciplinary Core Idea: Matter and Its Interactions
Evidence Of Student Attainment:
Students:
  • Make observations and measurements to identify materials based on their properties.
Teacher Vocabulary:
  • color
  • hardness
  • reflectivity
  • electrical conductivity
  • thermal conductivity
  • response to magnetic forces
  • solubility
  • density
  • measurement (quantitative and qualitative)
  • data

  • nonmagnetic
Knowledge:
Students know:
  • Materials have different properties-color, hardness, reflectivity, electrical conductivity thermal conductivity, solubility, and density.
  • Measurements of a variety of properties can be used to identify materials.
  • Measurements should be made in standard units (e.g., grams & liters).
Skills:
Students are able to:
  • Identify the phenomenon through observations about materials, including color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility.
  • Identify the evidence and collect data about the observed objects in standard units (e.g., grams, liters).
  • Collaboratively plan the investigation.
  • Identify materials based on their properties.
Understanding:
Students understand that:
  • Standard units are used to measure and describe physical quantities of materials such as weight, time, temperature, and volume. These measurements will assist in the identification of the materials ( e.g. powders, metals, minerals, and liquids).
