Antifreeze and Water Ratio Graph

Have students analyze the graph. Inform them that “ethylene glycol (%)” refers to the percentage of antifreeze mixed with water when topped off in a car. Have students use mathematics to interpret the results and implications of this graph. Students should be able to come up with the following:

  • The function of antifreeze is to lower the freezing point of water in cars.
  • The best antifreeze/water ratio that is most effective is 60% antifreeze and 40% water.
