Density

Density

We did an experiment on Density.

Question
What happens when you drop an egg into ordinary drinking water and an egg into salt water?

Observation
The egg in the glass of ordinary water sink to the bottom
The egg in the salt water floated to the top.

Conclusion
This happens because salt water is denser or heavier than ordinary water. It was easier for the egg to float.

  1. Hi Po,

    What a fabulous lesson you have learnt in science club today! I wonder if that means that it is easier to float in a salt water swimming pool?
