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 wire
balloons 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.
