DOES THE SIZE OF A BUBBLE AFFECT HOW FAST IT FALLS ?
Problem Question:
Does the size of a bubble affect how fast it falls ?
RESEARCH:
- Bubbles can occur in many things from soap to chewing gum
- A soap bubble is a thin film of soap particles that is filled with either gas or air
- Bubbles are fun to create in chewing gum and blowing into a liquid through a straw
- Bubbles occur in soda drinks as well to help them keep their fizz and taste
- In essence, all liquids have the ability to make bubbles
HYPOTHESIS:
the weight and size of a bubble affect how fast it will fall
MATERIALS:
Pencil, foam, drinking straw, bubble solution, wide shallow bowl
PROCEDURE STEPS:
- Fill the bowl with bubble solution
- Poke the pencil through the side of the foam cup, near the bottom
- Remove the pencil
- Push the drinking straw through the hole so that It goes all the way inside your cup.
- Turn the entire bubble pipe upside down into the bubble solution
PROCEDURE STEPS CONTINUED:
- Lift the bubble pipe
- Blow into the straw gently so it forms a bubble at the top of the cup
- After a small bubble forms, twist the cup quickly release the bubble
- At the same time hit the stopwatch
- Time how long it takes for the bubble to hit the ground. Record it in a data table
PROCEDURE STEPS CONTINUED:
- Blow 9 more small bubbles, record how long it takes for them to fall as well
- Blow ten large bubbles, using the technique described above. Record it in the data table
- Calculate the average time it took each type of bubble to hit the ground
