What did we do in class today?
Negative Feedback and the Nervous System
Learning Target: I will explain the role of negative and positive feedback in regulation of homeostasis. Pick up lab notebooks and take plant masses. Share data with your group. Calculate percent change in mass. Warm-up: On the feedback handout from yesterday (with food on it), use the diagram to answer the questions on the back. 1. Finish BILL the body, discuss plant response reading 2. Discuss negative and positive feedback 3. Introduce the nervous system HW: 1/31- No homework, study for quiz tomorrow (cell signaling, plant control mechanisms) 2/1- Watch and take notes over Bozeman immune system video in BILL http://www.bozemanscience.com/immune-system 2/4- Watch and take notes over Q10 in STATS SECTION of BILL http://www.bozemanscience.com/q10-the-temperature-coefficientwww.bozemanscience.com/q10-the-temperature-coefficient 2/5- Complete Transpiration lab

Body Plans and Feedback
Learning Target: I will describe the general location of major organs/systems. Pick up lab notebooks and 3 handouts at front of room. Pick up iRespond remote. No warm-up 1. Water potential quiz and practice 2. Plant masses and data sharing 3. BILL the body 4. Feedback loops handout HW: Brain reading- take notes in BILL Remember, the assignment for the water potential video will also be due when we return (See 1/28 post)
Your snow day assignment is to read and take notes in your BILL over section 39.3 in your textbook and over the "Gravity" and "Mechanical Stimuli" parts of section 39.4. Learning Target: I will describe what environmental factors impact transpiration in plants.
Hand in plant hormone superheroes to red bucket. Warm-up: A) Explain the role of guard cells in transpiration. B) Explain an adaptation of plants to limit water loss. C) Describe the role of stomata in plants-include their location D) Describe what variables may impact transpiration rate. 1. Lab set up 2. Notes: plant response to environment HW: Watch and take notes in your STATISTICS SECTION of your BILL over the water potential video linked below. Open note stats quiz tomorrow. http://www.bozemanscience.com/water-potential/?rq=water%20potential Cell Signaling in Plants
Learning Target: I will describe cell signalling in plants. Pick up handouts by mailboxes. Warm-up: Describe what is happening in each quadrant of the two diagrams in as much detail as possible (don't worry, I know we haven't covered this yet)
HW: Complete pre-lab on a separate sheet of paper (complete 1-3 on handout- read and take notes over background, watch video and take notes, answer "getting started" questions, hypothesize) Lab video: Required: https://www.youtube.com/watch?v=h9oDTMXM7M8 Helpful, but not required. May support your reading: https://www.youtube.com/watch?v=mc9gUm1mMzc Cell Signalling
Learning Target: I will describe the steps in cell signaling. Opener: Warm-up 1: Answer the questions below using your reading notes
1. Cell signaling discussion Closer: 2. Diagramming cell signaling HW: Complete labels lab and agar cube lab (no graph needed for agar cube). Be sure to follow the lab setup guidelines for the agar cube lab. Unit Exam 1
HW: •Set up BILL for unit 2. •Read and take notes in BILL over reading assignment (color version sent via Remind). Color version will only help you with images, but is not required. Test Review and Practice
Learning Target: I will describe how the structures of biological molecules and organelles influence their functions. Warm-up: On the post-it provided, write your most pressing question for tomorrow's test (please write your name). Place your post-it on the whiteboard. 1. Membrane and transport discussion 2. Q&A session 3. Multiple choice practice/white boards HW: Study for test, make sure vocab is done, BILLs due tomorrow Labs now due FRIDAY. Not on today's handout: Quaternary (4th) level of protein structure.
Warm-up: Which of the cells below would you expect to diffuse most quickly? Explain your reasoning.
Diffusion Lab and Cell Membrane Learning Target: I will describe aspects of cell structure that impact diffusion rates. Warm-up: Define Diffusion. Define osmosis. Why are both important for maintaining homeostasis? Work Session: 1. Agar Cube Diffusion Lab in Pairs 2. Nucleic Acids Closer: 3. Plasma Membrane Building HW: Labs due WEDNESDAY 1/23 Have you started your vocab? Are you studying NOW? Are you INTERACTING with your notebook? Food Label Lab Instructions:
