Science Lab Experiment: Weighing Air
Demonstration Weighing Air
Object: To find out whether air has weight or not.
Materials: scales, balloons, twist tie, air
Method: The materials were set up as shown in the diagram.
The empty balloon was weighed and the weight
was recorded. The balloon was filled with
air and weighed.
Observations: The balloon which had been filled with air was seen
to move scales downward.
This showed that the air in the balloon was heavier
than in the empty balloon.
Data:Weight of balloon and tie and air = 2.8 g
Weight of empty balloon and tie = 2.8 g
Weight of air = 0.8 g
Conclusions: It was concluded that air has weight.
