  7. Warm UP: Identify the independent, dependent & controlled variables. Some studies suggest that mint stimulates the brain. Mrs. Rauch decided to experiment on her class by giving half the class a peppermint while taking the test and the other half nothing. Then she compared the scores of the peppermint kids to the rest of the class.

  8. What is the independent variable? Some studies suggest that mint stimulates the brain. Mrs. Rauch decided to experiment on her class by giving half the class a peppermint while taking the test and the other half nothing. Then she compared the scores of the peppermint kids to the rest of the class. Whether student gets peppermint or not

  9. What is the dependent variable? Some studies suggest that mint stimulates the brain. Mrs. Rauch decided to experiment on her class by giving half the class a peppermint while taking the test and the other half nothing. Then she compared the scores of the peppermint kids to the rest of the class. Scores on the test

  10. What are the control variables? Some studies suggest that mint stimulates the brain. Mrs. Rauch decided to experiment on her class by giving half the class a peppermint while taking the test and the other half nothing. Then she compared the scores of the peppermint kids to the rest of the class. Same test at same time to same types of students.

  11. What is the control group? Some studies suggest that mint stimulates the brain. Mrs. Rauch decided to experiment on her class by giving half the class a peppermint while taking the test and the other half nothing. Then she compared the scores of the peppermint kids to the rest of the class. Students that do not get peppermint.

  12. What is the experimental group? Some studies suggest that mint stimulates the brain. Mrs. Rauch decided to experiment on her class by giving half the class a peppermint while taking the test and the other half nothing. Then she compared the scores of the peppermint kids to the rest of the class. Students that get peppermint

  13. Order the following from biggest to smallest. Hint: Change all to same unit 200g 8kg 400mg • 8 kg  200g  400mg 1 kg = 1,000g 1,000mg = 1 g 200g 8,000g 0.400g

  14. Write the equation that shows how plants make their food. Sun CO2 + H2O  C6H12O6 + O2 What is the name of this process? Photosynthesis What are the products of photosynthesis? Oxygen & Glucose

  15. A phainopepla bird eats mistletoe berries then leaves its droppings with undigested seeds where it perches. Mutualism What kind of relationship exists between the phainopepla & mistletoe?

  16. A cactus wren builds its nest in a cholla cactus to protect its young from predators such as raven. There is no harm to the cactus. Commensalism What kind of relationship exists between the wren & the cactus?

  17. What do stars stars E & G have in common?? • They are about the same temperature

  18. What factor decides what will happen to a star at the end of its life cycle? • Its Mass

  19. Describe the process occurring in the mantle of the picture below. Convection Current Hot rises and cold falls

  20. What type of zone is this? What type of zone is this? What type of zone is this?

  21. Identify the type of rock likely to be found at each of the labeled locations below. A – Sedimentary B – Metamorphic C - Igneous C A B

  22. What is the best unit for measuring distance in space? • A light year

  23. Which of the following is true about acceleration? • Acceleration is speed in a given direction. • Acceleration is a change in either speed or direction. • Acceleration is distance travelled in a given amount of time. • all of the above

  24. Which statement best summarizes the scientific concept shown in the cartoon? • A falling body accelerates at a constant speed. • B. The motion of an object is constantly changing due to magnetic forces. • C. The force of friction causes an object in motion to move faster. • D. A body in motion will remain in motion unless influenced by an outside force.

  25. If all the forces acting on a moving object are balanced, then the object will: A. slow down and stop B. change the direction of its motion C. accelerate D. continue moving at a constant velocity

  26. A bird is flying through the air. The wings of a bird push air downward. Because of Newton’s 3rd Law, the air must also be: • Pushing his wings downward • Pushing the bird forward • Pushing his wings at a constant speed • Pushing his wings upward
