Teacher Instructions: Go to www.Brainpop.com Sign in edhpop Password edhpop1 Go to Science Go to “Matter and Chemistry” Go to “Compounds and Mixtures” Play video and have students take graded quiz as a class, then go through powerpoint. Have students copy definitions of elements, compounds and mixtures, and have them turn in definitions with classification activity to their science teacher.

2. MATTER

3. WHAT IS MATTER? Anything that has mass and takes up space.

4. STATES OF MATTER Solids- tightly packed molecules, definite shape, does not conform to shape of container. Liquids- “slippery” molecules, definite volume, conforms to shape of container. Gases- lots of space between molecules, takes up all the volume of a container.

5. ELEMENTS Found on the Periodic Table Cannot be separated into smaller pieces and still retain the characteristics of the element.

6. COMPOUNDS Made of 2 or more elements chemically combined together. Have a FORMULA!

7. MIXTURES Two or more substances mixed together. NO chemical reaction has taken place! Can be separated by physical means.

8. HOMOGENEOUS MIXTURE Uniform in appearance No visible “chunks” Metal mixtures are alloys.

9. HETEROGENEOUS MIXTURES Not uniform in appearance Has visible “chunks”

10. Classify the following by element, compound or mixture. If the substance is a mixture, identify whether it is homogeneous or heterogeneous. 1.NaCl 2. Kool-Aid 3.Potting soil 4.14K gold 5.Vegetable soup 6.CaCO 3 7.Magnesium sulfate 8.Aluminum 9.Hydrogen 10.Creamy peanut butter
