Description
"The Secret of Ups and Downs" PPT courseware
When playing with submarines, we discovered that the amount of water in the submarine determines the ups and downs of the submarine. What does the ups and downs of general objects have to do with it?
Arrange these six objects in order of size
Objects: mineral water bottle ( ), apple ( ), pebble ( ), plastic foam ( ), rubber ( ), paper clip ( ).
Arrange these six objects according to their weight
Objects: apple ( ), pebbles ( ), mineral water bottle ( ), rubber ( ), plastic foam ( ), paper clip ( ).
Our research plans
Research project: The ups and downs of objects are related to their own weight
Speculation: When the volumes are the same, the heavier object sinks first
Experimental method: comparative experiment
Conditions to be changed: the weight of the object
Conditions that remain the same: the volume of the object
in conclusion:
1. The ups and downs of an object are related to its own mass and volume.
2. Objects made of different materials, if they have the same volume, heavy objects will sink easily; if they have the same mass, small objects will sink easily.
3. Objects with large volume and small mass tend to float, while objects with small volume and large mass tend to sink.
