1. Today is Wednesday, September 19, 2012 HOMEWORK: Read Chapter 2, Lessons 2 and 3 for TOMORROW Warm Up
With the person sitting beside you, take turns drawing a plant cell and then an animal cell on your white board. Share them with each other before you erase and give the other person a turn. ALSO, OPEN YOUR NOTEBOOKS TO YESTERDAY’S VOCABULARY TERMS.

3. Wednesday, September 19, 2012 Standards/Objective: TLW demonstrate an understanding that similar cells are organized to form structures by discussing the different groupings of cells to form tissues, organs and organ systems. Warm-up: On white boards, LW partner up and practice drawing a diagram of a animal cell and a plant cell, each taking a turn to draw one of them. LW identify organelles learned and their function. Show students a football, basketball and a badminton/ping pong ball LW demonstrate an appropriate use of each Discuss connection between and objects shape and it’s purpose Instruction: Organelles  cells  tissues  organs  systems Organelles work together to help a cell function Cells have many different sizes and shapes. Not all cells have the same job Examples: there are branching (nerves), flat (skin) and round cells (blood) Show students a tree branch, leaf and a saucer. Which object matches which cell shape. How do the shape of each cell (nerve, skin, blood) match its function? Same type of cells working together create a tissue. (Ex. Muscle, bone, nerve tissue) Different types of tissues work together to form organs. Each organ performs a main job. (Ex. Stomach, eyes, ears, heartstem, roots, leaves, flowers) Skin is an example of an organ. Explain each tissue and how they work together. Different organs work together to form organ systems. Look at a website that explains how each level builds on one another and watch a BrainPOP movie on cells.

6. Shape and Purpose…..

7. 3 Different Shapes Cells Have….
Branching Cells
Flat Cells
Round Cells
Take a look at page 42 in your textbooks, please.

8. Here we have pictures of a tree branch, leaf, and saucer
Here we have pictures of a tree branch, leaf, and saucer. Which picture matches which cell shape?
How does the shape of each cell (nerve, skin, blood) match its function?

9. After cells we get…..
The same type of cells working together produces tissues (examples include muscle tissue, bone tissue, and nerve tissue)
Look at page 44

10. After tissues we get….
Different types of tissues work together to form organs. Each organ performs a job. Examples include the stomach, eyes, ears, and heart. In plants, examples include roots, stem, leaves, flowers
Also on page 44 and 45

11. Different organs work together to form organ systems.
After organs we get….
Different organs work together to form organ systems.
Look at page 46

12. Here we have it explained by other sources…..
