1. SALT WATER VS FRESH WATER
The similar and different characteristics

2. What’s the difference?

3. What is Salt Water?
Salt water is water that has a higher concentration of dissolved salts.
Salt water is made during the movement of water on land over time.  The components of rocks are eroded and become part of a "salty" solution.
Salt is not the only component in salt water, other chemicals are also classified as salts.

4. What is Fresh Water?
Fresh water is water that has a low concentration of dissolved salts.
It can be in a liquid, gaseous or solid state.
The word fresh does not mean that the water is drinkable.

5. Where Can We Find It? Salt Water
Oceans contain most of the world’s salt water
Salt water makes up 97% of the world’s water
Salt water may also be found in swamps, marshes, lakes and estuaries
Fresh Water
Fresh water makes up only 2.5% of the world’s water
Most lakes, rivers, marshes, bogs and swamps contain freshwater
Glaciers also contain a lot of our fresh water

6. SIMILARITIES
Salt water and fresh water can be found in all three states – gas, liquid or solid
Both fresh water and salt water have dissolved materials
Bodies of salt water and fresh water are habitats for many different organisms.

7. DIFFERENCES Salt Water Fresh Water Has a higher viscosity
Has lower viscosity
Higher density
Lower density
Lower freezing point ( -1.9⁰C)
Higher freezing point (0⁰C)
Higher boiling point (103⁰C)
Lower boiling point (100⁰C)

8. Back to the Eggs
Is there a difference between the water in the containers?
Why is one egg floating and the other has sunk?

9. Swimming in the Ocean
When you go swimming in the ocean, your body will float on top of the water and this does not happen if you swim in a fresh water lake. In fresh water lakes or rivers we have to use swimming skills to float. The density of salt water makes it heavier, and your body is now able to float on top.
