Discuss these and any properties that were left out. Discuss the ingredients of bubbles and discuss how much soap and how much water should be used to make the best bubble mixture that would create big bubbles that would not pop quickly. Have students make a prediction as to how much soap and water should be used for the ideal bubble solution. For example, if the student predicted that half water and half soap would make the best mixture, that is the mixture that will be in their jar. Have students test their mixtures one at a time.
Students vote to determine the best bubble solution.
Discuss why the ideal solution worked the best. In order to assess student understanding, let them explain the reasons to each other. Have students compare their bubbles to this product's bubbles. The follow-up activity will be the main method for evaluating the student's understanding of the material. This class is a self-contained class, therefore, precautions have been taken in the planning of the lesson to assist those who do not understand the material.
