Experiment Ideas

First Draft of Our Experiment

Question: What can sound move? Can we see it move? How much force does it exert on the object?
   Independent Variables: temperature, substances.

Hypothesis: Objects will move farther in warmer temperatures because air particles are able to move more freely in higher temperatures. Objects that are lighter have less mass and therefore require less force to move, so light objects will also move farther.

Experiment:
   Materials Needed:

• water
• a pot
• a burner 
• speaker system
• string
• wooden block
• thermometer 
• meter stick
• feather
• dry ice

   Procedure:

• Place the object (steam, dry ice, or feather) to be moved in front of the speaker
• Turn on the speaker
• Measure how far it moves
• Record data

Data: none so far

Conclusion: none so far

Today in class, we did more research and found that the speed of sound depends on temperature. We created a rough draft of our experiment. The independent variables will be the temperature and type of object we are trying to move. The dependent variable is the distance that sound can move the object in a certain amount of time. We wrote out a procedure and we will be revising our plan next week if necessary.
