  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

  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.
