3 different kinds of clear dishwashing rulers liquids straws commercial bubble solution plastic trash bags to cover tables water Four 50-ml beakers glycerin Procedures: Mix three bubble solutions in separate beakers using the following proportions of liquids: 5 ml dishwashing liquid, 30 ml water, and 5 ml plain glycerin. Note: If you want to make a lot of bubble solution, just use larger quantities of each ingredient, keeping them in the 1:6:1 proportion. Put 40 ml of commercial bubble solution in a fourth beaker. To test a solution, pour it onto the plastic trash bag on your table top, put your straw into one of the small bubbles and blow more air into the bubble. Continue blowing air into the bubble until it bursts. Using centimeters, measure the diameter of each bubble print left behind on the trash bag. Repeat this procedure three times for each of the different solutions. While you are doing this activity, make some observations about the colors and other physical characteristics of the bubbles. Record your results on the data sheet. group’s Complete the class data table and write a conclusion for the activity.
