4. III.Hypothesis IF a bubble is produced using (brand of gum), THEN its bubble will be larger than the bubble produced by (other brands of gum).

5. Variables: Independent Variable Brand of Gum Dependent Variable Diameter of Bubble Constants Same masses of gum Same flavor Same chewing time Same number of chews Same method of producing bubble Same amount of air Same mouth

6. IV. Experiment A. Materials: 1 piece of Brand #1, #2, and #3… Ruler Stopwatch

7. Procedure 1.Unwrap 1 piece of Brand #1. 2.Chew Brand #1 for 30 seconds, 1 chew/sec, and produce a bubble. 3.Measure the diameter of the bubble (mouth to farthest point). 4.Record data in Table #1. 5.Repeat #2-4 to produce a 2 nd and 3 rd bubble. Record data in Table #1. 6.Wrap gum in wrapper and throw away in trash can. 7.Repeat steps #1-6 for the remaining pieces of Brand #2 and Brand #3. 8.Calculate the average diameter for each brand of gum.
