1154 - What materials dissolve in water and what materials do not dissolve in water easily

Imagine you're mixing stuff in a glass of water. Some materials will break apart and mix with the water, while others won't. Here's a list of which ones do and don't dissolve:

Materials that dissolve easily in water:

1. Sugar: Think of putting sugar in your favorite drink - it disappears into the liquid.
2. Salt: Salt will dissolve in water and make a salty solution.
3. Baking soda: It's like sand, but it breaks apart and mixes with the water.
4. Food coloring: You can add a few drops to water and it will change the color.
5. Juice (like fruit juice or syrup): It mixes with the water and makes a yummy drink.

Materials that don't dissolve easily in water:

1. Sand: If you put sand in a glass of water, it will stay at the bottom.
2. Paper: Try putting a piece of paper in water - it won't dissolve.
3. Wood: A wooden stick or spoon won't break apart in water.
4. Oil: If you mix oil and water, the oil will stay separate from the water.
5. Metal: Metal objects like a spoon or a key won't dissolve in water.

So, if you mix something with water and it breaks apart or disappears, it probably dissolved. If it stays the same or separates from the water, it probably didn't dissolve.
