INTRODUCTION 
This experiment offers the demonstrations that reveal that fresh water is less dense that salt 
water. 

OBJECTIVES 
Students will understand that: 
• saltwater has a higher density than freshwater. 
• less dense matter will lie above more dense matter. 

Experiment:
Two glasses of water will be kept in front of
the students. One of the glasses will have salt in 
it (children need not know this). Drop a lemon 
into the glass of plain water and ask students 
to predict the outcome. The lemon sinks. Next, 
drop the lemon into the salt water and students 
will be surprised to see that the lemon floats. The 
teacher needs to build the excitement by asking 
questions and encouraging students to find out 
answers.
