We did a hovercraft experiment and then we wrote it up using the correct structure.

TITLE
Balloon Hovercraft
QUESTION
How does a hovercraft hover?

HYPOTHESIS

I predict that the balloon hovercraft will hover over the table.

EQUIPMENT  AND MATERIALS:
Cd, balloon, bottle cap.

PROCEDURE:
Step 1:Using a hot glue gun, glue the bottle cap over the CD hole.
Step 2: Blow up a balloon. When it is fully inflated twist the end so no air comes out.
Step 3: Stretch the balloon end over the bottle lid.
Step 4: Open up the cap and place the CD on a table.
Step 5: Untwist balloon and let go.

OBSERVATIONS/RESULTS:
I found out that the air from the balloon creates a path of air.

CONCLUSION:
The air from the balloon creates a cushion of moving air between the disc and the surface. The air lifts the CD and reduces the friction which allows the CD to hover across the surface.
