If you were left on a desert island by yourself, what steps would you take to survive? 10/21/15 Date:10/21/15Topic:Behavioral HomeostasisPage # ___

Today in Room 326… ADMIT SLIP: If you were stuck on a desert island, what steps would you take to survive? HW: Answer the analysis questions CONTENT OBJ: SW design a lab protocol to investigate mealworm behavior LANG. OBJ: SW communicate verbally in groups to complete lab AGENDA: Discuss AS Signaling Notes Lab Design Mealworm Lab Date:10/21/15Topic:Behavioral HomeostasisPage # ___

Admit Slip Shareout What steps would you take? Why?? (What feelings would you have?) What part of the brain would be responsible for your various actions? Which body system would control your actions?

How is a signal passed along? Homework share out Watch: kr7dGPOwzsA kr7dGPOwzsA kr7dGPOwzsA (3 min)

Neurons connect to each other k *Action potential = peak of electrical impulse (must be reached to transmit a signal)

Signal Transmission How does a signal travel from one neuron to the next? *Neurotransmitter = a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse (signal)

Draw & Label in Journal* What is this called??

Survival Mechanisms You are on the desert island and you are hungry Discuss in pairs (2 min): Describe the pathways required to fix this situation. How is this an example of homeostasis?

Behavioral Homeostasis* = Tendency of an organism to maintain equilibrium (ie internal stability) by behavior means Perceptions of need (i.e. need to eat, need to be safe)  physical response Simple terms: Behaviors or actions required to maintain homeostasis

Mealworm Lab Larval stage of mealworm beetle Need to maintain homeostasis like all organisms. Today: Investigate their behavior to infer about their needs Infer = to deduce or conclude from evidence Inference = a conclusion based on evidence

Lab Design

Journal Set-Up Behavioral Homeostasis Lab Objective: To observe mealworm behavior in response to different environments Hypothesis: (you decide this with your group!) Ex. Most mealworms will move towards the jello, some will go to hay. Materials: -mealworms -testing chamber -materials: 1.____ 2.____3._____4.____ Procedure: Data/Results: See attached sheet

Mealworm Data Table Pull up document

Jobs 1. Materials gatherer (bring chamber and fill with small amounts of 3 substances) 2. Mealworm gatherer/returner (pick out at least 5 live mealworms for petri dish/return at end) 3. Timer (in charge of cellphone timer- should be left running for 10 min straight 4. Clean up manager (dump chamber components and wash in sink) Questions???

If a new student arrived in this class today and wanted directions to the cafeteria, how would you explain them to him/her? 10/22/15 Date:10/22/15Topic:Behavioral Homeostasis Day 2Page # ___ Write in journal!

Today in Room 326… HW: Write a laboratory abstract for the superworm lab CONTENT OBJ: SW write and carry out an experimental protocol to investigate the behavioral homeostasis of superworms LANG. OBJ: SW read about superworms and communicate verbally in lab groups to design and carry out lab AGENDA: Superworm Reading Lab Introduction Superworm Behavior Lab Analysis of Results Date:10/22/15Topic:Behavioral Homeostasis Day 2Page # ___

Superworm Reading You have 10 minutes. (Set Timer)

Self-Designed Lab Today YOU are in complete control! Goal for end of today: Have a beautifully organized lab report written in your journal. 1. Objective 2. Hypothesis 3. Protocol (with very clear/specific directions!) 4. Data (you decide how to organize!) 5. Analysis (what do your results tell you?)

Student Steps: 1. Determine variables with group Examples: Light intensity, Moisture, Food source, Texture, etc. Dependent vs. independent variable? 2. Design and write lab protocol 3. Determine how data will be recorded 4. Conduct lab! 5. Analyze results (What does your data tell you?)

Abstract Writing 1) Read through and highlight document 2) Ask any questions within lab groups 3) Ask for clarification from me. **This is due by class time tomorrow via and therefore must be TYPED!**
