Survival behavior Subject Data gathering methods Advantages of this approach Disadvantages of this approach Location Data gathering methods Advantages Disadvantages Type of survey Data gathering methods Advantages Disadvantages Excellent Good Needs improvement Missing Behavior is specific, observable and measurable here in Davinci community. One of 3 (at left)is missing or not explained Two of 3 are missing or not explained Survival behavior is not addresse d Person used may be good candidate, and/or you only partially justify your choice Missing You poorly explain/1 or 2 approaches Missing Poor Missing Poor Missing Poor Missing Poor Missing Poor Poor Missing Missing Poor Missing Poor Missing Poor Missing Poor Missing If chose CASE STUDY Person used for case study is ideal candidate, Person used for case study is a and you clearly explain why. reasonable candidate, and you explain why You clearly explain at least 3 different You partially explain/2 approaches you’d use to gather data from this approaches person You clearly discuss why a case study would Partial give you insight into this survival behavior You clearly discuss the limitations of a case Partial study in understanding this behavior If chose OBSERVATION (field or lab) You clearly describe the location and explain Partial why it is ideal for observation. You describe at least 2 behaviors you would Partial be looking for during observation. You explain 2 advantages of this approach. Partial You describe 2 limitations of this approach. Partial If chose SURVEY You clearly address how you would obtain Partial survey participants and who they are You include 5 sample questions (not open Partial ended) that would be in your survey. You address 2 advantages of conducting a Partial survey. You address 2 challenges to conducting a fair Partial and representative survey The PNS • Takes in information from external environment using sense organs • Sends to SENSORY CORTEX of brain for processing • MOTOR CORTEX of brain decides on an action. • Sends instruction to muscles to carry out action. Interneurons • Connect: –PNS with CNS –Within PNS, sensory neurons (afferent) with motor neurons (efferent) PNS Activity Objective: How can I measure the speed of my PNS? What affects my reaction time? Hypothesis: Procedures: Pair up. Person #1 holds ruler vertically with the 30 cm mark at top. Zero cm is at bottom. Person #2 has fingers poised aver zero cm mark at bottom. Person #1 drops the ruler without telling person #2 when they will do it. Person #2 grabs ruler when they see it drop. Data/Observations. Make the following table: Do 10 trials with each hand. TRIAL # 1 2 3 Calculate average by adding numbers and diving by 10. 4 5 Repeat for each person. 6 7 8 9 10 AVG (cm) LEFT HAND RIGHT HAND Class data Name 1 2 3 4 5 6 7 8 9 Left hand (average cm) Right hand (average cm) Analysis: 1. Which person had the fastest hands? 2. On average, which of hand is the quickest? 3. Why do you think there is a "delay" from the time you see the ruler drop to the time your hand catches the ruler? Describe the pathway of neural communication from sensory organ to muscle. 4. Name two other variables that might have played a role in how fast your reaction time was in this lab. 5. What do you think would happen if your partner asked you a question while they dropped the ruler? Try it for 5 trials. Why do you think this makes a difference? 6. Do the experiment by yourself, using one of your hands to drop and the other to catch the ruler. How were your results different? Why do you think this is so? 7. Draw a bar graph comparing the average times of the fastest hand for each person at the table. How to calcuate reaction time Let’s say it dropped on average 8 cm. You have to convert that to meters so divide by 100. 8 cm ------- = .08 m 100 Use the formula: speed = distance / time We will use the rounded up number of 10 m/s for gravity’s speed .08 m 10 m/s = -------now solve for t t .08 ------ = .008 sec 10 This is how long it took you to see the ruler drop, react, and catch the ruler. Today’s Key Concepts • Sense organ (eye, ear, taste buds etc) • Sensory neurons (afferent neurons) • Interneuron (connect PNS and CNS and sensory neurons with motor neurons) • Motor neuron (efferent neurons) • Sensory and motor cortexes of CNS. • Muscle (Effector. Ex: hand) • Somatic and autonomic divisions of PNS HOMEWORK • Think about a time in your life when you have been really scared. • You don’t need to share it with the class, but you must be willing to write about it next class (privately). • Write a short paragraph about it. Bring in. • WE CANT DO OUR ACTIVITY NEXT CLASS WITHOUT IT!
