Simple Mixtures: Sand and Water

Simple Mixtures: Sand and Water
When you mix two or more things together, you make a mixture. Think about sand and water. If you put sand and water in a cup and shake it, you have a mixture. These things are still themselves, even when mixed.

You can see sand and water in a mixture. The sand does not disappear in the water. This is because sand does not dissolve in water. When something dissolves, it seems to disappear in the liquid, like sugar in water.

If you have sand and water mixed together, you can separate them. One way is to let the sand settle to the bottom. If you shake sand and water in a bottle and let it sit, the sand will go to the bottom. This is because sand grains are heavier than water and they sink.

Bigger sand grains will settle faster than smaller sand grains. The water might look cloudy at first, but as the sand settles, the water will become clearer. This is how you can separate sand from water in a simple way.

So, sand and water make a simple mixture. You can see both parts, and you can separate them. It’s like playing with toys; you can put them in a box together, but you can always take them out again!
