Review Chapter 1 Quiz 1 Jello Lab Scientific Method “Never leave that till tomorrow which you can do today.” Benjamin Franklin To continue learning about the scientific method assess learning about living things. Title: Biology 8/31/06 Class Topics Objectives: Thursday, December 19, 20194:00 PM

  2. Emergency Procedures • Fire – SINGLE FILE • Out door to right, down stairs, outside in parking lot - Stay as a group • Tornado – SINGLE FILE • Out door to right, down stairs and to the right, kneel facing the lockers in the brown hallway - Stay as a group • “Secure the Building” • Stay in your seat and be quiet - some students may have to move to a lab table • Evacuation – SINGLE FILE • Travel as a class to south doors and move down sidewalk to load busses

  3. Class Assignments What By When • Deer: Predation or Starvation 8/31/06 • 2A only – Measurement W.S. 8/31/06 • Read 14-20 8/31/06 • Jello Lab 8/31/06 • W.S. Can you spot the Scientific Method? 9/5/06 • Read People didn’t get hurt as much back then 9/5/06 • Read – Fractured Futures 9/5/06 • Chapter 1 Test 9/7/06 Due this class period • Due next class period • Due in the future

  4. Grade Sheet

  5. Conclusion Analyze Data Collect Data Experiment Hypothesis Problem Research

  6. Research • What in Jello is being digested by detergents? • What in detergents is digesting the Jello? • Links for research • Gelatin • What are enzymes? • Enzymes and detergents • Detergents’ enzymes

  7. Data

  8. Analysis

  9. Conclusion • Which detergent had the most change? • Which had the least change? • What do you think that says about the amount of enzyme? • What do you think that says about the strength of the enzyme?

  10. Report findings • Publish findings in paper or journal. • Explain experiment’s materials & methods • Explain whether or not your hypothesis was supported or not.

  11. W.S. “Can you Spot the Scientific Method” • Changes • Science Skills portion (3rd and 4th pages) • Eliminate Stage A • There are two of these that would work together for a hypothesis • Only using 4 steps (leave 5 and 6 empty) • Problem/Research • Hypothesis • Experiment • Conclusion

  12. Theory • Definition: • A belief or principle that guides action or assists comprehension or judgment • A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena. • From Dictionary.com • A set of related hypotheses that have been tested and confirmed many times • Biology

  13. Is it Science? • “People didn’t get hurt as much back then.” • “Fractured Futures”

  14. The Consent Late in November, on a single night Not even near to freezing, the gingko trees That stand along the walk drop all their leaves. In one consent, and neither to rain nor to wind But as though to time alone: the golden and green Leaves litter the lawn today, that yesterday Had spread aloft their fluttering fans of light. What signal from the stars? What senses took it in? What in those wooden motives so decided To strike their leaves, to down their leaves, Rebellion or surrender? and if this Can happen thus, what race shall be exempt? What use to learn the lessons taught by time, If a star at any time may tell us: Now.
