Little scientist experiments: Sink and float

Here is another easy experiment made by our Little scientist to learn the sinking and floating concept.

Tools: a beaker, tweezers.



Small objects such as coins, cotton balls, cereal pieces, rocks, raisins, cork, etc

Key science concept:

Objects sink or float in water.

What to do:

1. Fill the beaker with water.

2. Select a few objects to be placed in the water.

3. Predict which objects will float and sink.

4. Use the tweezers to place objects into the water. Watch what happens to each object.

5. Did you predict correctly?

6. Repeat this experiment with new objects.

For his experiments Little Scientist used the Primary Science Lab kit available from
