Beautiful+Bubbles

= Does adding glycerine to a bubble mixture increase the size of bubbles or the length the bubbles can stay in the air? =

= __Task 1: Answer these Questions__ =


 * 1) What are the basic ingredients of a bubble solution and what do they do? Water and detergent. Water has a surface layer called surface tension. Soap is flexible. When soap is added to water it makes the water more elastic or stretchy. Soap stabilizes bubbles - it strengthens the weakest part of the bubble - it stops any part of the bubble from stretching too much.

2. How does a soap bubble form?

A bubble is a thin fillm of soapy water. Most bubbles are filled with air. The film that makes the bubble has three layers. The first is a layer of soap molecules, then a later of water, then another layer of soap molecules
 * 1) What mixture makes the best bubble solution? dish soap, glycerin and corn syrup.
 * 2) What is surface tension? Surface tension is a force within surface layer of liquid.

==  __Task 2: List your independent, dependent and controlled variables:__  ==

__1. Independent variable:__ amount of glycerin

__2. Dependent variable:__ stop watch

__3. Controlled variables:__ size of the wand, amount of detergent and amount of liquid

=  __Task 3: What is the hypothesis for your experiment?__  = The longest bubble will have the most glycerin.

=  __Task 4: What equipment do you need for your experiment?__  = Glycerin corn syrup stopwatch permanent marker jars with lids pipe cleaners dishwashing liquid soap distilled water and measuring cups and spoons

=  __Task 5: List all steps in the method of your experiment (try and include a diagram or video that helps explain):__  = 1. 2. 3. 4. 5.

__**Task 6: Observation and discussion**__

Note down what you noticed as you did each experiment. Try and include an image or a video or photos of your experiment.
