  2. A pure substance that cannot be broken down into simpler substances AND is made of only 1 kind of atom is called what? Element 1 - $100

  3. 1 - $200 • A mixture that appears to contain only one substance is called what? • Solution

  4. 1 - $300 • Which of the following is a mixture? Silicon, carbon dioxide, or salt water? • Salt water

  5. 1 - $400 Which of the following is not a pure substance? Milk, oxygen, water • Milk

  6. 1 - $500 • Why is water classified as a compound? • Because it always has 2 hydrogen atoms for each oxygen atom

  7. 2 - $100 • This kind of change occurs when a material changes shape or size, but the material itself does not change. • Physical

  8. 2 - $200 In the following examples, which one is NOT an example of a physical change: boiling water, bursting a balloon, or toasting a marshmallow? • Toasting a Marshmallow

  9. 2 - $300 • Which of the following is NOT a clue that a chemical change has occurred? Bubbling, production of gas, or change in shape? • Change in Shape

  10. 2 - $400 What are three possible clues that a chemical change has occurred? • Production of a gas, smell, change in color, a new substance has been created, heat, light, or sound production

  11. 2 - $500 Explain why water breaking down into hydrogen and oxygen is a chemical change.

  12. 3 - $100 • Flammability is what kind of property? • Chemical

  13. 3 - $200 • Density is a ____________ property. • Physical

  14. 3 - $300 • Aluminum’s melting point is 1220 degrees F. • Physical Property

  15. 3 - $400 • Viscosity is a measurement of how easy something flows. Would this be a physical or chemical property? Why? • Physical

  16. 3 - $500 • Use 3 words to describe what a chemical property is. • Ability to React

  17. 4 - $100 • What is another name for a homogeneous mixture? • Solution

  18. 4 - $200 • In a solution, what is the substance that does the dissolving called? • Solvent

  19. 4 - $300 • Water is the universal what? • Solvent

  20. 4 - $400 • True or false: a homogeneous mixture only has 1 substance in it. • false

  21. 4 - $500 • If I leave a mixture of saltwater out in the sun for a while, the water will eventually evaporate, leaving only the salt. Why is this possible in mixtures? • Because substances in mixtures are only physically combined, not chemically

  22. 5 - $100 • Which property of water allows it to stick to other things? • Adhesion

  23. 5 - $200 • Which property of water allows it to stick to itself? • Cohesion

  24. 5 - $300 Which property of water allows it to resist changes in temperature? • Specific Heat

  25. 5 - $400 • Name the 5 main components of the water cycle? • Evaporation, Condensation, Precipitation, Transpiration, Run off

  26. 5 - $500 • Using the words respiration, decay and photosynthesis, explain the carbon cycle. • Carbon is respired into the atmosphere by living things, carbon is broken down by decay and put back into the environment from wastes and dead

  27. Final Jeopardy • During a science lab, students placed 10 grams of sugar in a test tube and heated it over a burner. The sugar began to melt and turn into a colorless liquid. Continued heating caused the liquid sugar to turn brown. The sugar eventually began to smoke and changed into a solid black residue with a mass of 6.2 grams. What can students conclude from this experiment? –identify the physical and chemical changes. • Physical Changes – Sugar Melting into a liquid • Chemical Changes – Turned Brown, began to smoke, changed into a solid black residue. Change in mass is because 3.8 grams of sugar were released as smoke during the chemical change
