Day 1

Start 2 New Pages (a left and right) Add it to your TOC Mystery Cells Start 2 New Pages (a left and right) Add it to your TOC

Learning Target: I can identify the differences between animal and plant cells.

The situation Use a cup to draw 3 circles on each page (2 pages) in your SN.

The situation Police contacted the administration of Westwood Middle School early this morning. A dead body was found in the field behind our school. Investigators think it was murder and are asking for our cooperation to help solve the crime.

Interview with the medical examiner The situation “ We found no external marks on the body, suggesting no physical trauma. We did, however, recover some unique cells from inside the body that have been saved for analysis. Before we can determine what exactly they are, we need to decide whether or not they belong to a plant or animal species.”

The situation Research In order for you to be of assistance to the police department, you need to learn more about cells, and the differences between them.

You will look at ALL of the slides eventually, but only 6 today. To learn more, you will use the classroom microscopes to view slides of different cells. You will look at ALL of the slides eventually, but only 6 today.

Take your time to carefully draw what you see. Today, you will look at each slide for 4 minutes. Take your time to carefully draw what you see.

When you get to a microscope… Write down the number of the slide/microscope you are looking at. Draw what you see in the circles in your science notebook. Make a prediction - Is it a plant OR animal cell? Write one! Explain why.

Let me show you…

Each circle should have 3 things… Slide Number Drawing Prediction & Explanation (plant or animal) 3 Plant (why?)

Day 2

Plant/Animal Predictions Turn to your next open page. Prepare to copy the chart on the next slide.

(Explain why you think this) Slide Number Prediction (Plant or Animal) Reasoning (Explain why you think this) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

Plant/Animal Predictions Fill in the 6 you already looked at. We will look at the other slides. Fill in the chart for these too. You don’t need to draw anything. You will have ~1 minute per slide.

Mystery Cells: Reflection Please respond to the following: (below your plant/animal chart or on the next open page) Do all cells look alike? Give some examples of how they are different. Give some examples of how they are the same. Why might some cells look different from others?

Day 3

Microscope Parts

Lets Practice! Focus Magnification - Coarse Adjust - Fine Adjust 40x (large knob = large change) - Fine Adjust (small knob = small change) Magnification 40x 100x 400x

Lets Practice! When I say “break,” go to the scope where you did your FIRST drawing and wait for instructions.

Day 4

Start 2 New Pages (left & right) The situation Create-A-Slide Start 2 New Pages (left & right) Add it to your TOC Today we will make some of our own slides.

The situation Draw 1 circle on each page (2 pages) in your SN. Label one “Plant” and the other “Animal” Plant Animal

You are an animal. An elodea is a plant.

Prepare your own slides: Plant = Elodea cells Animal = YOUR cheek cells! Draw what you see in the correct circle!

Plant Cells (Elodea)

Animal Cells (Human Cheek)

Day 5

Plant and Animal Cell Comparisons Start a New Page Add it to your TOC

- Copy the following Plant Animal

See pages 68-69 of your textbook. Use the PICTURES at the bottom of each page. Write down 5 observations EACH about plant and animal cells. Try to find as many differences as you can!

5 Observations each (pages 68-69) Plant vs. Animal Cells 5 Observations each (pages 68-69) Plant Animal

Animal Cells (Human Cheek)

Plant Cells (Elodea)

Plant Cells (Onion)

Copy the following Chart The situation Copy the following Chart (bottom ½ of your page) Plant Cells Animal Cells Shape Organization Unique Structures

The situation Shape What have you learned or noticed about the shapes of plant and animal cells? Plant: Often boxes or square shaped (but sometimes circles) Animal: Often irregular or circles (“blobs”)

The situation Organization What have you learned or noticed about the organization of plant and animal cells? Plant: Very organized (stacks and rows) Animal: Often random or clumped

The situation Structures What structures do plant cells have that animal cells do not? Plant: Cell Wall Large Central Vacuole (LCV) Chloroplast Animal: Lysosome

Cell Wall Large Central Vacuole (LCV) Chloroplast Create this table on a new page. Use at least ½ of the page! Plant Cell Part Function/Job Cell Wall (pg. 68) Large Central Vacuole (LCV) (pg. 74) Chloroplast (pg. 72)

Functions/Jobs of Cell Parts Please look over the following pages to complete the table. Cell Wall – pg. 68 Chloroplast – pg. 72 Large Central Vacuole (LCV) – pg. 74 (HINT: Look in the table at the bottom of the page) Use the HEADINGS to guide your search for information!!!

Pair and Share What is the function of each? - Try to summarize each using only 1 or 2 words!

Cell Wall Plant Cell Part Function/Job gives structure and support to the cell This is why plant cells have a defined shape!

Large Central Vacuole (LCV) stores water and other materials Plant Cell Part Function/Job Large Central Vacuole (LCV) stores water and other materials When this isn’t full the leaves of your plant droop. This means “I need water!”

uses the energy from sunlight to produce food for the plant Plant Cell Part Function/Job Chloroplast uses the energy from sunlight to produce food for the plant This process is called photosynthesis and it is a chemical reaction.

Large Central Vacuole (LCV) Plant Cell Part Function/Job Cell Wall Gives structure and support to the cell (This is why plant cells have a defined shape.) Large Central Vacuole (LCV) Stores water and other materials (When this isn’t full of water you will see the leaves of your plant droop. This means “I need water!”) Chloroplast Uses the energy from sunlight to produce food for the plant (This process is called photosynthesis and it is a chemical reaction.)

Plant cells have: Cell Wall Large Central Vacuole (LCV) Chloroplasts Provides structure and support for the cell Large Central Vacuole (LCV) Holds water and other materials Chloroplasts Contain chlorophyll (= Green color) Play a role in photosynthesis (= energy from Sun)

Day 6

Mystery Cells - Evidence The situation Mystery Cells - Evidence Start a New Page Add it to your TOC

The situation Mystery Cells - Evidence Drawing Observations (5 or more)

The situation Your task The medical examiner has attached a copy of the microscopic views of the cells found in the dead body. Draw the image in your science notebook (Be Detailed!) Write 5 or more observations (Be Specific!)

Evidence!!! Invading cells Human body cell

The situation Your task Next, submit your findings to the police department for formal review. Make your claim AND support it with evidence!!! ATTN: SLP Police Department It is my belief that the cells found in the dead body are . . . (plant or animal) I believe this because… Copy and Complete
