...area. 5. Dip a straw into the soap solution within your beaker. Touch the surface of your film (near the center of the film) with the straw at approximately a 45 degree angle. 6. Gently blow a bubble-dome: continue blowing until it pops. You may take more than one breath to blow a bubble, for they can get quite large before popping. 7. With a ruler, measure the diameter of the rings of soap suds left by the popped bubble-dome. If the dome was irregular in shape, measure 2 or 3 diameters and average them. 8. Record the data in an appropriate data table. 9. Repeat procedures four times for each soap brand. 10. Graph the results and answer questions based upon your data table. Remember to also include a table and a graph devoted to cost effectiveness. You will need to record the price of each soap brand to perform this calculation. (So you will need two data tables and two graphs) Observations- Data Table for diameter of soap bubbles in centimeters Soaps Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 Dawn 13cm 15cm 19cm 20cm 20cm Polmolive 32cm 27cm 29cm 29cm 27cm Joy 36 cm 27cm 18cm 29cm 27cm Ajax 25cm 33cm 33cm 28cm 30cm Soap Name Average Diameter of 5 Trials Cost of Detergent Average Diameter/ Cost of Soap Dawn 19.4cm 0.26¢ 66.92 Polmolive 29cm 0.25¢ 116 Joy 27.4cm 0.23¢ 114.13 Ajax 30.8cm 0.15¢ 205.33 Data Table for cost and effectiveness of detergent Graph for diameter of soap bubbles in centimeters Graph for cost and effectiveness of detergent Analysis-After 20 bubbles had been blown and recorded I saw that there was not a pattern in the bubble sizes.
