Presentation Transcript

  1. Welcome to Mr. Bennett’s AP Biology at Career Center HS Please pick up the 2 handouts & a 3x5 card. Thank you! (on the table by the door)

  2. Roll Call • Remind 101 subscription • text @a3kg4 to 81010 OR • rmd.at/a3kg4 on your smart phone • Seating chart • Cell phone policy • 3x5 card • Front: Name & home school • Back: period • Dominican Republic Service trip • July 24 – July 31, 2017 • Info meeting 9/8/15 • Termite Lab….and related Essential Questions

  3. Essential Questions • LO 3.40 The student is able to analyze data that indicate how organisms exchange information in response to internal changes and external cues, and which can change behavior. • LO 3.41 The student is able to create a representation that describes how organisms exchange information in response to internal changes and external cues, and which can result in changes in behavior. • LO 3.42 The student is able to describe how organisms exchange information in response to internal changes or environmental cues. • Science Practice 4: The student can plan and implement data collection strategies appropriate to a particular scientific question.

  4. Today’s goal • Make observations of termites • with & without drawn lines • skip 1st page in lab notebook • Think about doing an experiment to test your observations

  5. Day 2 • Get student info handout….books Friday • Remind 101 subscription • Missing 2 people (parent registered), RJR swim?? • text @a3kg4 to 81010 OR • rmd.at/a3kg4 on your smart phone • Dr. Nichols announcement….I’ll read • Cell phones in the bin….off or muted….please and thank you

  6. Essential Questions • LO 3.40 The student is able to analyze data that indicate how organisms exchange information in response to internal changes and external cues, and which can change behavior. • LO 3.41 The student is able to create a representation that describes how organisms exchange information in response to internal changes and external cues, and which can result in changes in behavior. • LO 3.42 The student is able to describe how organisms exchange information in response to internal changes or environmental cues. • Science Practice 4: The student can plan and implement data collection strategies appropriate to a particular scientific question.

  7. Scientific Method • Did any of you use the scientific method over the summer? • What is the scientific method?

  8. Did any of you use the scientific method over the summer? • What is the scientific method? • a way to solve problems

  9. Did any of you use the scientific method over the summer? • What is the scientific method? • a way to solve problems - STEPS

  10. Did any of you use the scientific method over the summer? • What is the scientific method? • a way to solve problems – STEPS • Problem/question • Research • Hypothesis/plan • Experiment • Results • Conclusion • Revise hypothesis/plan • Need volunteer

  11. Did any of you use the scientific method over the summer? • What is the scientific method? • a way to solve problems – STEPS • Problem/question • Research • Hypothesis/plan • Experiment • Results • Conclusion • Revise hypothesis/plan • Need volunteer • 3. What are the elements of good experimental design?

  12. Hypothesis – Write “The hypothesis to be tested is…..” • Independent & dependent variables - IV: experimenter manipulates DV: what is measured • Control group & experimental group • Constants – same temp., same volume, equipment, time - Write “The constants are….” • Controls • Missing ingredient • No caffeine, no enzyme, dark conditions • Random sampling • Large sample size (n) • Repeated – multiple trials • Graphs • Label axes w/ units • Keep same scale • Title • Start at X & Y vertex • Connect dots • Key – if more than one line Good Experimental Design

  13. Did any of you use the scientific method over the summer? • What is the scientific method? • What are the elements of good experimental design? • What is meant by “science as a process?” • Science is not finite. It is a process of learning more with additional research findings. • Lab notebook handout • Skip 1st page • Title & date • Pre-lab • Purpose/overview • Personal Account • Discussion • Conclusion

  14. Termite Lab – Notebook Set-up • Title & date • Pre-lab • Termites • Scientific method • Purpose/overview • Personal Account – most work is here • Observations (Day 1 & day 2) • Hypotheses • Experimental design • Data • Graph (?) • Discussion - Did data support or refute hypothesis? • Conclusion • What did you learn? • What is the significance? • What is your revised hypothesis (if needed)?

  15. Students • Today you will conduct your experiment for your termites • Fire drill route • Left on sky walk • Down steps • FAR corner – between CC & Carter parking lots • On grass Phones in bin….off or muted…please & thank you

  16. Educational Service Trip to the Dominican Republic – July 2017 Information Meeting – Thursday, September 8th @ 6:30PM Only 25 students can participate – all students eligible. See Mr. Bennett for more details.

  17. Day 2 Termite lab • Ensure you have a consistent procedure • Get termites & conduct experiment • Collect data • Finish writing up lab in notebook • Due?? • Tuesday

  18. Hypothesis – “The hypothesis to be tested is…..” • Independent & dependent variables - IV: experimenter manipulates DV: what is measured • Control group & experimental group • Constants – same temp., same volume, equipment, time - “The constants are….” • Controls -Missing ingredient -No caffeine, no enzyme, dark conditions • Random sampling • Large sample size (n) • Repeated – multiple trials • Graphs • Label axes w/ units • Keep same scale • Title • Start at X & Y vertex • Connect dots • Key – if more than one line Good Experimental Design

  19. Termite Lab – Notebook Set-up • Title & date • Pre-lab • Termites • Scientific method • Purpose/overview • Personal Account – most work is here • Observations (Day 1 & day 2) • Hypotheses • Experimental design • Data • Graph (?) • Discussion - Did data support or refute hypothesis? • Conclusion • What did you learn? • What is the significance? • What is your revised hypothesis (if needed)?

  20. WHAT’S GOING ON?????? The only two trail pheromones identified with certainty are the unsaturated aliphatic alcohol (3Z,6Z,8E)-3,6,8-dodecatrien-1-ol and the diterpene (E,E,E)-neocembrene, which have been found in several species [1]. These compounds are very active and occur in different, sometimes unrelated, families. The necessary amount needed for trail- following can be as low as 0.01 pg/cm (pg = picogram = 10-12 gram) trail. To positively be identified as a trail pheromone, a compound must induce trail-following and be present in the sternal gland of the termites.
