Materials• Apples• Bananas• Grapes• Limes• Oranges• clear
container with water
• paper towels
Procedure1. Fill the clear container with
water.2. Place a fruit in the container.3. Watch what happens. Did it
sink or float?4. Repeat 1-3 with each fruit.5. Records and discuss results.
Variable•We changed
the types of fruits tested.

Apple Results
• The apples floated !
Bananas Results• The banana
floated!
Grape Results• The tiny
grapes sank!
Lime Results
• Wow! The limes sank !

floated !

find out that not all heavy fruits sank. Our hypothesis was incorrect, just because an object has greater mass does not mean it will sink. We had lots of fun doing this experiment.
