Rachael and Amelia conducted a science fair project to test if different shaped cookie cutters used as bubble wands would produce bubbles of different shapes. They prepared a bubble solution and used various shaped cutters like circles, squares, dinosaurs, and stars. However, regardless of the wand shape, all the bubbles produced were circular. They concluded that bubble shape is not dependent on the wand shape.

2. blow different
shaped bubbles if we
use different shaped
cookie cutters as
Hypothesis: wands?
bubble
Different shapes of
cookie cutters will
make different bubble

3. Preparation:
Gather supplies that we need for
the project:
– Science notebook and pencil
– Dish washing liquid
– Glycerin
– Water
– Measuring cups and spoons
– Different shapes of cookie
cutters
Dinosaur, star, heart, football,

6. Make Bubble
Solution
• Measure 4 1/2 cups
water
• Measure 1/2 cup
dishwashing liquid
• Measure 4 tablespoons
glycerin

8. Begin
Experiment
• We recorded each cookie cutter
shape first, then we drew the shape
of the bubble that the cookie cutter
made.
• The first shape of cookie cutter we
used was a circle. We recorded the
shape of the bubble as a circle.
• The next shape of cookie cutter was
a square. We recorded the shape of
the bubble as a circle.
• We used all of the different shaped

19. Results:
Each cookie cutter
produced circle-
shaped bubbles,
regardless of the
original cookie cutter
shape.

23. Conclusion:
It does not matter
what shape is used
as the bubble wand,
the bubbles will
always be a circle
