Let's read p.16 and 17 together.
Cellular Processes – the processes that organelles perform to carry out the cell’s life functions.
Diffusion – the movement of molecules (or other particles) from an area of high concentration to an area of low concentration until they are evenly distributed.
Concentration - the number of particle of a substance in a certain volume.
Osmosis – movement of water across a membrane in response to concentration differences.
Let's start today's lesson by revisiting the Cells & Organelles worksheet.
This time it is for marks, so work carefully.
Attention! Attention! This is not a drill, people - this is the real deal!! 😁

Now that you have been reintroduced to both the plant and animal cells, let's see if you can communicate your understanding of the structure, function and relationship of the cells' parts through the use of an anology.

Assignment
🠞 Choose a type of cell 🠆 plant cell or animal cell.
🠞 Choose something to which to compare your cell. (For instance, "An animal cell is like a factory." This is your analogy.
🠞 Choose eight (8) organelles from the list below and create an analogy for each one. The analogy should "match" or parallel the actual function and make sense within your analogy as a whole.
🠞 Create a "poster." This can be done on a regular sheet of paper. The poster should include:
🠞 The project is due any day you are school from Feb 8-11. Plan your time wisely, as I will not accept late projects.

| Here's a great example of a cell analogy project. Take a look if you want some inspiration. |
Grading Rubric:
Notice that this project is out of a lot of marks. This is a great way to give yourself a mark boost to start this class out on a positive vibe. 👊👏💪😆
Learning Goals:
Studying cells helps us understand how organisms function.
Cellular organelles work together to carry out life functions.
Cellular processes enable organisms to meet their basic needs.
Success Criteria:
I can…
…list out why studying cells is important.
…label organelles on a plant & animal cell diagram.
…indicate the functions of organelles.
…describe diffusion & osmosis and provide examples.

Anticipation Guide
What do you already know about tissues, organs and body systems? Let's find out!
Why Should We Learn About Cells?
It allows us to
The
Cell Theory
Cells, Cells, They're Made of Organelles...
An organelle is structure within a cell.
Organelles work together to carry out certain functions that support the life of the cell.
These functions include transporting in nutrients, taking out wastes, generating and releasing energy for cell use, making necessary substances and reproducing.
Just try to not sing along with the chorus. I dare you. 😉
Cells & Organelles
All living things are made up of cells - either animal cells or plant cells, depending on the organism. All cells are made up of organelles.

An organelle is a structure within a cell. Organelles work together to carry out all the functions that support the life of the cell.
These functions include:
Let's make like an organelle and do some work.
How do scientists see cells and organelles? By using a microscope of course.
Microscopes allow us to peer into the unseen world around us.
🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬
Watch this video to see some of the tiny wonders that we often don't realize exist all around us. This imagery is stunning.
🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬
Microscopes are delicate pieces of equipment that consists of several parts, that all serve a specific function.
Time to get back to work and learn about the parts and their functions.
🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬
If we were in school, we could use an actual microscope. But, we can still get a feel for the microscope in an online environment.
Check out this virtual microscope.
Feel free to look at some slides by clicking on "EXPLORE" when you get there.
Be sure to look at:
Hello, my name is Ms. Murphy.
You may remember me from grade 8 day. I was the lady that was lighting everything in sight on fire (maybe I even lit *you* on fire 😀).
🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
We will be learning completely virtually until February 8th (updated). So, while we are virtual, our period 2 class will run from 11:45-2:15. We will meet on Teams at 11:45 every day.
Each day will consist of a mixture of the following: lesson, practice, activity and/or video. The virtual lessons, and any related material can be found on this blog.
I have created a course timeline that contains hyperlinks to take you to each day's material. I will pin it in the upper left corner for easy access. I will update the timeline as needed.

Before we can get into the science, we have some paper work to get out of the way. Please have your parents look over the three documents posted here, as well as checking out the rest of the information.
On a piece of paper, write "We have read and understood the CIS, syllabus and safety rules." Sign this paper yourself. Have your parent/guardian sign this paper and send me a picture of it on Edsby.

Hunt Hints:
👉 A good detective will exercise control over the investigation.
👉 Detectives have to work hard. There is no free lunch.
👉 A good criminal must fly under the radar, even when in plain sight.
👉 There is a science to catching criminals.
👉 The CSI unit takes pictures of the crime scene and goes through the mug shots.
👉 Correctly following the clues is an art form.
👉 Crime is a messy business.

Each team of detectives will turn in one completed "Police Report."
All teams with a perfect set of answers will be entered into a draw.
WHat CaN wE wiN?? 😏
The winning team will not have to write up one lab this semester (excluding the titration lab). They will get all the fun of an experiment without the bummer of the lab report.
