Water is very important .We need water to drink, to wash our hands, to cook, to water plants and many other things. Without water, the plants would die and people and animals would go thirsty. What is water?

Water is made up of two hydrogen atoms, and one oxygen atom. When these atoms come together, they form a strong bond that can’t be broken.

What is Table salt?
Sodium chloride
Designed for cooking
Has many ingredients
1. Potassium iodine- stabilizer
2. Glucose (sugar) - prevent the potassium iodine from breaking down.
3. Calcium silicate- anti-caking additive

What at Sea salt?
Used for cooking and cosmetics
A natural form of salt
Course grind (bigger chunks)
It’s extract from ocean water through evaporation process

What is sand?
Loose particle of hard broken rocks.
Normally brown in color
Found on beach

What is calcium chloride?
another form of salt
capable of absorbing a lot of liquid
harmful to humans and live plants
used to preserving commercial canned foods and removing ice from roadways
The purpose of my paper is to gain an understanding of water, how and why ice melts differently with table salt, sea salt, sand and calcium.

RESEARCH REPORTIntroductionWater is a liquid that freezes and also melts at 32*F (0*C). Melting and freezing points are temperatures when a solid substance turns to a liquid. Liquid is a substance that flows to fit its container.Water Water is a liquid that is odorless, colorless, and tasteless. Water freezes and melts at 32*F (0*C). As water freezes it expands by one-eleventh. The amount of pressure on the water when it is freezing changes the melting point. Water that reaches 40*F it is at its maximum density. The molecules in water are always rapidly moving, until it gets cold and then they start slowing down. Water can be in three different forms: liquid,...
