Mixtures & Solutions

Foss science 5th grade unit vocabulary

QuestionAnswer
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.
