Foldable! Fold your paper in half (hamburger style). Cut one of the halves through the middle up to your fold to make two flaps. Label the left flap "Pure substances" and the right flap "Mixtures".

Which side do elements go under? How about compounds? Remember, elements and compounds are both pure substances!

Elements (left side, top half) A pure substance (only 1 type of particle) that cannot be separated into simpler substances by physical or chemical means. Examples: Carbon (C) Oxygen (O) Hydrogen (H)

Compounds (left side, bottom half) A pure substance composed of 2 or more different elements that are chemically combined. COMPOUNDS CHEMICALLY COMBINE Examples: Water (H2O) Carbon dioxide (CO2) Salt (NaCl)

Mixtures (right side, front) Two or more pure substances that are not chemically combined

Homogenous Mixtures (right side, top half) Homo = same The whole mixture has the same appearance and properties. You cannot see different parts of the mixture. Examples: Kool-aid Air Bronze (mixture of copper and tin)

Heterogenous Mixtures (right side, bottom half) Hetero = different The mixture looks different throughout. You can see the different parts of the mixture. Examples: Salad Noodle soup Sand
