Can two objects occupy the same space?

 

Experiment: Volume

 

Hypotheses: Ask children what they think will happen to the water level if we add pebbles to a glass that is half full.

 

Material:

    • • One clear drinking glass per child

 

    • • Pebbles

 

    • • Water

 

    • • A washable marker for each child

 

Manipulation:

    1. 1. Pour water in your glass until it is half full.

 

    1. 2. Use the marker to draw a line on the glass to indicate the water level.

 

    1. 3. Gently add one pebble at a time to the glass. Watch the water level.

 

Explanation: The space an object occupies is called volume. Originally, the water occupied a certain volume. This volume was indicated by the line you drew on your glass. When you added pebbles, the water level increased since the water and the pebbles cannot occupy the same space. Since the pebbles are heavier than the water, they fell to the bottom of the glass and pushed the water upwards. A greater volume was occupied by the water and the pebbles. This explains why the water level is higher than at the beginning of the experiment.
