| Question | Answer |
|---|---|
| mixture | something made by combining two or more ingredients |
| solution | a mixture that looks clear because the solute has dissolved (disappeared) in the solvent |
| solute | something (gas, liquid or solid) that is disolved in a solvent |
| solvent | a liquid or gas in which you dissolve a solute in; an example of a solvent is water - you can dissolve salt (solid solute) in the water (solvent) |
| dissolve | solids are often dissolved in liquids; for example, you can dissolve sugar in water; dissolve means to 'melt in' and become a part of the water till you can't see the solid anymore |
| atom | the smallest piece of all things in the universe; it can exist by itself or can be joined to other atoms to make a molecule; an example is an atom of hydrogen |
| molecule | if I took a drop of water and I put it under a very very strong microscope, I could see that it is made of many molecules of water; if I tried to divide one molecule of water it would change into oxygen and hydrogen (then, it wouldn't be water anymore); |
| element | elements are made of one kind of atom; on earth, 118 elements have been found; those elements can be combined (joined) to make all the matter (things) on the earth. |
