`Bubbles Bubbles and More Bubbles                                         Sandra M. Green                Frazier School                               4027 W. Grenshaw                               Chicago IL 60624                                       (312) 534 6880             Objectives:1.  The students will develop skills in observation. 2.  The students will be able to determine which solutions will create     the largest bubbles and why?3.  The students will be able to compare the shapes and colors of bubbles.4.  The students will be able to perform a science experiment.5.  The students will be able to make a bubble stand.6.  The students will learn that all liquids form bubbles but their life    span is short.7.  The students will learn that soap breaks the surface tension.8.  The students will learn how to design their own bubble makers.Materials:water    corn syrup     sugar     glycerin     gelatin     straws     wireballoons     string     scissors    wire clothes hangers     aluminum pans  paper cups     pipe cleaners     newspaper     plastic containers         dishwashing liquid (Dawn, Joy, Dove, Palmolive).Strategy:    This activity will be introduced to eighth grade students.    Students will be given various handouts on bubble making substances.  They     will follow directions and design their own bubble blowers, including     cutting 4 vertical 1" cuts in each end of a straw and bending back the 4    equal sized strips on each end.  Then they will cut it 1/2 way through in     the middle of the straw and then blowing through one or both sides of the    tube to create a two ended bubble pipe that can blow a bubble in a bubble    etc.      For a super size bubble, students will thread a string through two straws    to make a rectangle or square, with the straws forming two opposite sides    and the strings forming the other opposite sides.  They  will dip it in one    of the solutions to make super big bubbles.    Students will dip their blowers into various solutions to determine which    solution creates the biggest bubbles.    Are the bubbles the same size?    Which receipe makes the longest lasting bubbles?    Bubbles come in all sizes, do they come in all shapes?    What makes bubbles pop?    Can bubbles be connected ?    How long do bubbles last and why?    How many colors are seen in a bubble?Performance Assessment:    The students will draw the colors in the bubbles in the order they see    them from the top down.     Each group will be graded 50% on their oral report and 10% each on their     academic behavior in contributing to the group for whatever role they    play in that group, assuming that there are 5 per group.                                                      `
