Lesson 2

Billions of Bubbles

Objectives:

• Students will participate in observational investigations in order to recognize that scientists repeat experiments to verify results.

• Students will use a graph to represent  results of science experiments.

Time Required:

• Two-one hour sessions 

Vocabulary:

• bubbles
• blow
• solution

Materials:

• Several containers for water

• Water

• Different kinds of liquid soap (bubble bath, hand soap, dishwashing liquid, laundry detergent, shampoo, etc.)

• Large Bubble Bottle cutout:   Make a bubble bottle cutout out of bulletin board paper with two columns.   Label one column with YES and the other with NO.

• Story:  Bubbles, Bubbles, Everywhere by Melvin Berger and Dwight Kuhn

• Student Performance Evaluation

Advanced Preparation:.

• Fill containers halfway with water.

• Label each container with a different kind of liquid soap.

• Mix 1/8 cup of each soap into its corresponding container.

• Have paper towels nearby for spills.

Procedures:

• Read story Bubbles, Bubbles, Everywhere   to  set the tone for your bubbles experiment.
• Discuss with students that you will be testing different kinds of liquid soap to see which is best for bubble solution.
• Before beginning the experiment, have students make predictions of which liquid soap they think will be the best solution.
• Have students blow bubbles with each of the different solutions.  Which of the solutions create bubbles?  Which do not?   Record the findings on the bubble bottle cutout as students are testing solutions.
• Once students have completed testing the different solutions, discuss with class which solution worked and which did not.  Compare the predications with the actual results, "Are predictions the same as the actual results; different?"  Discuss results.
• Discuss why some of the solutions worked and which did not.

Evaluation:

• Use the Performance Evaluation to assess student's effectiveness during experiment.

Extension Activity:

• Students can complete Bubble Fill (number order sheet).

• Students can visit bubbles.org to play some bubble games.

Home Learning:

• Students will draw a picture of the experiment and if they are able write a sentence of what occurred.
