EXAM ANNOUNCEMENT & REMINDER: HOMEOSTASIS & CELL TRANSPORT EXAM WILL BE ON WEDNESDAY, 11 MARCH 2020. THE FORMAT WILL BE A COMBINATION OF MULTIPLE CHOICE AND OPEN ENDED SCENARIOS FOR YOU TO ANALYZE. TOPIC LIST IS BELOW. START REVIEWING IT NOW...
Friday, 28 February 2020. Introduction to homeostasis in a high altitude climber. Today is the transition from how cells control cellular "traffic" to how the whole organism maintains its internal environment in the face of a changing external environment; called homeostasis!
Monday, 24 February 2020. Introduction to additional methods of cell transport. Below is today's presentation to help us make sense of the weekend's homework in addition to the summative task we have in line for Wednesday this week.
Friday, 14 February 2020. Osmosis, Diffusion, & Cell Membrane Structure Review. Below is a PDF of the stations for today's review before the quiz. If you missed class, you can go through the stations and write your responses on the student packet in the "work missed while absent" folder. A PDF of the student packet can also be found below.
Wednesday, 12 February 2020. Red Onion Lab. Today's lab packet can be found below. REMINDER: Short 10 question quiz on Friday, 14 February 2020 as was mentioned last class. Topic covered will be those covered in the osmosis-diffusion presentation in the posting from 10 February below. Be able to determine a solution's tonicity and water flow in an osmotic event. Second, be comfortable with cell membrane structures as we covered in our cell membrane presentation from 4 February's posting.
Monday, 10 February 2020. Further investigation into osmosis & diffusion. Today will investigate water movement in cells and how the osmolarity effects a cell's behavior. The focus will be on defining the tonicity (concentration differentials between the internal and external cellular environments and the related changes to the cell as a result) of a solution and what a cell looks like in different environments.
Thursday, 6 February 2020. Introduction to osmosis and diffusion. The videos below will take the next step from the "Transport in Cells" packet you completed for homework last weekend. All the packets that have been handed in are on the front counter to pick up to use for this work.
Tuesday, 4 February 2020. Cell membrane bubble lab. Below you'll find the guided notes sheet and the packet to guide us through the cell membrane modeling activity we'll do today.
Friday, 31 January 2020. Introduction to Homeostasis. The Cucumber Crisis Activity. Below you will find the packet for today's intro activity. You will also find an electronic copy of the homework (Tranport in Cells) - HW material will need to be gone through and ready for Tuesday's (4 February) class.

You will have all of Thursday to complete any edits. Both sections will be graded on Thursday. The final file below is the schedule of when all sections of your report are due and when they will be graded. Use this to schedule your time to complete the draft sections for homework to have ready to edit in class.
The potential materials list is below, add only what you used from the list. Hole punch, straws, 60 mL syringe, various plant leaves, 250 mL beaker, plastic cups, soapy water & bicarbonate solution, graduated cylinder, hot water bath, ice water bath, lamp, ruler, meter stick, thermometers.
9 December 2019. Leaf Disk Lab Practice Run. The link below is to enter your data from the practice run of the lab. https://docs.google.com/spreadsheets/d/1hbPLBJKbt1pTuWqNPpmGdIZxvX9hGSplyzxB0qsSRFY/edit?usp=sharing
2 & 3 December 2019. Website Evaluation Lesson with the media center teachers. Use the following websites for the activity:
1. students will be spending roughly 10 minutes in groups of 4 looking at one of two websites above and noting what they see on post-it notes. 2. decide if what they found makes them more or less likely to use that site as a source for research. 3. as a class, we'll discuss the characteristics of a credible website using the "C.R.A.P." model and learn how to use that evaluation tool.

18-21 November 2019. Molecular modeling & the compounds of life. Below is a pdf of the packet used during the modeling lab we will begin today. You will use this to click on the links to check to see if your final build of a molecule is correct. Be sure to pay strict attention to the position of each element within the compound.
7 & 8 November 2019. Stomata density data analysis. The link below is for the data you collected in your stomata counts this week. Enter the average you found under the correct plant type. THEN, delete the density calculated for the power you did not use so the data is not skewed.
4 November 2019. Introduction to Plant Structure & Function. We will start the unit with an introduction into how plants are able to make energy from a few simple ingredients! See the packet below for the leaf casting lab we will do to understand what stomata are and what their job is. Below you will also find the introduction video for Part I's observations and questions table. There is also a tutorial from Mrs. Rojas on how to make a leaf casting.

Thursday & Friday, 5 & 6 September 2019. The niche concept and how species coexist within ecosystems is the focus of today's classwork. The video below will introduce you to how different species use the same habitat at the same time. The goal is to see the concept of niche and how in some cases, the niche is split up (aka partitioned) to make use of all opportunities within an ecosystem. There is an electronic copy of the student handout below so you can see the data in Figure 2 in color. Here is the order you should approach today: 1. look over your student handout for 5 minutes 2. watch the video of how Dr. Pringle studies the diets of the focal species 3. complete the reflection questions about the concept of niche and how it works 4. hand-in the completed packet
Wednesday, 3 & 4 September 2019. Today's work will introduce you to the basic concepts we will use in our ecology unit such as niche, organism, species, population, community, and ecosystem. The order of activities today will go as follows: 1. Lab safety quiz 2. "Niche: Every living thing has a role to play" reading and question set. I encourage you all to use a yellow highlighter from the box on the front counter to highlight key elements of the reading before answering the questions on the last page of the packet. 3. "Which Niche" activity. Use the 4 different ecosystem cards to get a better understanding of the concept of niche and how organisms take on specific roles that aren't duplicated in the same place within an ecosystem. Follow the directions closely for what you need to do on the front of the sheet. For the tables on the back, use any one of the species found on any of the ecosystem cards you look over to get a better idea of the concept of niche as we'll use it. Use the information in the "Niche" reading and/or your Chromebooks to search for acceptable answers on the web. In case you need the ecosystem cards to finish the work at home, they are at the back of the "Which Niche?" PDF file below. Have fun! Additional Resource: There is a Bozeman Science video clip to help you to better understand the concept of niche if you're still uncertain.
"Niche: every living thing has a role to play" Reading
Thursday & Friday, 29 & 30 August 2019. WELCOME TO NHS BIOLOGY!! Below you will find the lab safety agreement as well as the acknowledgement sheet that you will have signed by your guardian signifying that we covered proper safety in the lab as well as the syllabus for the course. Signed acknowledgement forms due next class, you cannot participate in a proper lab until it is signed and handed in. REMINDER: THERE WILL BE A LAB SAFETY QUIZ NEXT CLASS BUT YOU MAY USE THE LAB SAFETY GUIDELINES WE REVIEWED LAST CLASS.
