Your teacher Mrs. Jones

New words you will learn.

Word Meaning

Density It is the mass of the material in relation to the volume it takes up

Solve solution

Mineral It is a natural form of material found on earth

Ocean Sea

Viscosity Flow of liquid ( eg.water/oil and honey)

Evaporation Water that change from a liquid to water vaper

Interior land Not near the sea

Float Being buoyed up on water or other liquid

Temperature

How hot or cold it is

Sparingly To use little of it

LIFE IN WATER

The Earth consists 70% of water

There are 2 types of water on earth:

Fresh

Salt

water

Compare salt water and fresh water

Saltwater is denser than fresh water because it contains salt. The salt in the water is not the same as the salt you put on your food. It is another kind

of salt. Salt water flows slower than fresh water due to higher viscosity Salt water is denser than fresh water, so objects can float better on it. When it rains the fresh rainwater reduces the salt quality of the salt water When water evaporates from the sea, the salt remains behind.

Rainwater is always fresh water And sea water is always salty. Rivers and dams in the interior land have fresh water.

Sea water is salty Rivers, dams and lakes have fresh water

Fresh water Salt water

Taste no salt Rivers, dams, lakes Lower density Lower viscosity flow faster Freeze slower at 0 ° C Boils at 100 ° C degrees Objects sink easy Fresh water evaporates completely Rain water makes salt water less salt.

Taste salty Ocean/Sea Higher density is heavier Higher viscosity flows slower Freeze faster to ice, at 2 ° C Boils at higher temperatures Objects float easier Salt stays behind when water

evaporates

Hartbeespoort dam

I

It rains freshwater The Ocean Saltwater is heavier

Viscosity

How fast or slow the liquid runs.

Freshwater runs faster than salt water. Uses of Water.Fresh water Salt water

1. Drink to quench thirst

2. Drink 8 glasses a day.

3. Water is good for a healthy digestive Sistem

4. Cooked food in fresh water

1. Drink a little bit for medical use (gargle for sore throat )

2. Disinfect wounds

3. Seawater makes things sticky.

4. Swim in the sea for the joy of it and to relax.

5. A salt bath for relaxing your body

6. Many large ships can sail on the sea.

7. Animals and plants can live in seawater.

8. Saltwater Preserves food (Brine) eg. Tuna canned food.

Activity 1Think about more things you can do with Fresh- and Saltwater.

Use the pictures as clues to help you think.Instructions

Write in your homework book or on a loose sheet of paper.

1. 10 things what you can do with freshwater2. 5 things you can do with salt water.

Water is a very important recource

Water is Life! All humans, animals and plants on earth need water to live. Without water we will all die

Use water sparingly. This is a scarce resource.

Activity 2 How can we save water?Instructions

1. Think about ideas how you can help save water at your home.

2. Draw a picture of every idea in your home workbook.3. Write to each picture your idea is.

Activity 3 Art

Put on your thinking hat!Here are some ideas to inspire you to make your own unique picture. Be creative, use many colors and types of lines.

Go crazy. It's your creation!!!

Always brag with your work

Activity 4 Do this experiment.Experiment: Will the salt water and fresh water mix?

You need What to do
