  4. Explain the level of organization Using the following, put them in order: (cell, atom, organ, element, organism, macromolecule, organ system, molecule, tissue)

  5. Level of Organization • Subatomic particles • Atom • Element • Molecule • Macromolecules • Cell <--life begins here • Tissue • Organ • Organ system • Organism

  6. Describe a controlled experiment • What is a controlled experiment? • List the 6 steps of scientific method

  7. Compare • What is the difference between a hypothesis and a theory? • What is the difference between a independent variable and a dependent variable? • What is the difference between a control group and a controlled/constant variable?

  8. Experiment • A researcher is curious to find out what effect classical music has on people’s level of relaxation (as measured by heart rate). He suspects that listening to classical music will make people feel more calm and relaxed. He lets one group listen to classical music for one hour. He lets another group sit in a quiet room for one hour (i.e they hear no music). After one hour, he monitors the heart rate of each participant to measure their level of relaxation. • A) Independent variable? • B) Dependent variable? • C) Control Group • D) Experimental Group • E) Constant/Controlled Variables

  9. Movement • Explain what this is a diagram of. Talk about the movement of oxygen in this diagram

  10. What is the difference between…? 1) Trachea and esophagus. Name 3 differences including how they look

  11. Homeostasis • Explain how each system works to maintain homeostasis • Nervous system • Circulatory system • Respiratory system • Digestive system

  12. Functions • Functions for each system • Nervous system • Circulatory system • Respiratory system • Digestive system

  13. Unit Conversions 1) 453 m = _______ km? a) .453 c) 45.3 b) 4.53 d) .0453 2) 333 cm = 3.33 ___ ? a) dm c) m b) km d) mm 3) Convert the following metric unit: 23.6 cm • _________________ m • _________________ mm • _________________ dm

  14. 1) 453 m = _______ km? a) .453 c) 45.3 b) 4.53 d) .0453 2) 333 cm = 3.33 ___ ? a) dm c) m b) km d) mm 3) Convert the following metric unit: 23.6 cm • ___.236____ m • _______236______ mm • _________2.36________ dm
