  1. Nine Week Study Guide

  2. Definitions • Hypothesis- An educated guess to a scientific problem. • I.V.- The variable that changes in an experiment. • D.V.- The variable that is being tested or measured in an experiment.

  3. Definitions • Control Group- The group in an experiment that is treated normally. EX: Giving a plant water versus giving a plant Dr. Pepper. • Experimental group- The group in an experiment that is being experimented on. Ex: Giving a plant Dr. Pepper versus giving it water.

  4. Definitions • Constant- Things in an experiment that remains the same between the control group and experimental group. • Control- Factors in an experiment that the Independent Variable compares to.

  5. Scenario 1 • Title: Answers can vary; The effects of Starbucks Coffee on Cancer Tumors. • Hypothesis: Starbucks Coffee does or does not reduce the size of cancer tumors. • I.V.- Starbucks Coffee • D.V.- Size of the Tumor • Constants: Amount of days(6 Months) , X-ray

  6. Scenario 2 • Title: The effects of Breakfast on Thinking Ability • Hypothesis: Breakfast does and does not play an important role in one’s ability to think. • I.V.- Not having breakfast • D.V.- How well you are able to process information (thinking ability). • Constants- SAT-10, Same Instructor.

  7. 1. • Matter is anything that has mass and takes up space.

  8. 2. • Mass is measured in grams using a Triple Beam Balance.

  9. 3. • Milk Spoiling- C • Silver Tarnishing- C • Ice Melting- P • Evaporation- P • Leaf changes color- P • Water purified through distillation- P

  10. 4. • Density= Mass/ Volume • Mass Divided By Volume • 52g /73.5ml = 0.707= 0.71g/ml

  11. 5. • Concrete- M; Hetero. • Wood- M; Hetero. • Table Salt- P.S • Milk- M; Homo. • Sodium- P.S. • Pure Air- M;Homo.

  12. 5. • Blood- M; Hetero • Salad Dressing- M; Hetero • Soil- M; Hetero. • Paint- M; Hetero • Oxygen- P.S. • Nail Polish- M; Hetero

  13. 6. • Gases have an indefinite shape and an indefinite volume.

  14. 7. • Liquids have an indefinite shape and a definite volume.

  15. 8. • Solid particles stay in place. • Liquid particles move/slide past each other. • Gas particles spread throughout.

  16. 9. • Condensation is the change in state from a gas to a liquid.

  17. 10. • Evaporation is the change in state from a liquid to a gas.

  18. 11. • Gases are Non-Metals

  19. 12. • Air- M • Light- NM • Sugar- M • Water Vapor- M

  20. 13. • The rate of the reaction increases as time increases.
