Ned+Day+Three

== =__Lesson 3__= In this Unit we started off looking at the broad world of the 6 Kingdoms and then began focusing on the characteristics of the cells each. Now, we will continue to fine tune our focus and look at the cell itself, specifically the cell membrane. The students will individually go through a powerpoint presentation. They will create a annotated drawings of the different transport mechanisms that cells use.

Key Concept / Question
Cell Membrane Model. How do cells move things in and out of themselves, such as nutrients and waste?

Resources
Websites, computers, paper, textbook, board, flash drive with presentation

Warm Up
The students will have read the chapter covering the cell membrane model. Open the class by asking if they have any questions about the reading. If possible, see if other students can answer the questions.

Have the students name some of the key concepts or words that they believe are integral to this chapter. Write these on the board. If necessary, complete the list with the remaining terms.

Introduction
Have the students pull up the PowerPoint presentation that I have created on their laptops. (Have a copy on a flash drive just in case) Ask them to go through the presentation, taking notes and drawing where applicable.

Lesson
1. This is the presentation that the students are working on.

2. Be prepared, an integral part of the presentation is teacher/student discussion. The presentation requires that each student raise their hand and call you over for a brief discussion. At times, students will also be discussing with their neighbor.

3. After a few minutes of working, interrupt the students and tell them the objective for todays lesson. The Objective is to have them manually draw and recognize the various steps in diffusion, osmosis, and active transport. Also noting the differences between them.

4. Explain that if they are to finish early, they are to explore the websites in the "Extra! Extra!" section of the presentation.

5. In the last 20 minutes of class, have the students close the presentation and begin a class discussion. They are to name the transport systems and list the steps involved with each. Write the answers on the board next to the list generated at the start of class.

Evaluation / Assignment
The students are to draw each model of transport systems, at least 3 stages (before, during, after). Under each drawing, they are to provide a caption as to what is going on in the picture. To be done by the next class.
