This document defines key terms related to mixtures and solutions. It explains that a mixture is formed when two or more materials are stirred together, while a solution forms when a material dissolves in water. Common elements that make up the Earth and human body are also listed. Key terms defined include solute, solvent, saturated solution, concentration, dilute, and precipitate.

Mixtures and Solutions
Vocabulary

2. +
Mixture: two or more materials
stirred together.

3. +
Property: a characteristic of an
object, something you can observe
(color, shape, size, or texture)

4. +
Solution: a special mixture formed
when a material dissolves in water.
Note: solutions
must be CLEAR!

5. +
Dissolving: when one material
disperses uniformly into another
material, so that the first material
seems to disappear.

6. +
Elements: cannot be reduced to
simpler substances (everything on
earth is made from these).
copper
gold
aluminum

Solute: a substance that dissolves
in a solvent to form a solution.
Solvent: a substance that dissolves
the solute to form a solution.

11. +
Saturated Solution: a solution in
which as much solute as possible
has been dissolved.

12. +
Concentration: the amount of material
dissolved in a measure of liquid.

13. +
Dilute: to make a solution less
concentrated, usually by adding more
liquid.

14. +
Volume: is the 3-dimensional space
occupied by something (like a
liquid).

15. +
Chemical reaction: when two or
more materials are mixed together
and a change occurs.

16. +
Precipitate: a solid material that
forms as a product of a reaction.

17. +
Atom: the smallest particle of an
element. Atoms are the building
blocks of matter.

18. +
Molecule: The smallest part of a
substance that is made up of two or
more atoms.
