Overview
Knowing how organelles function makes it easier for students to understand how cells survive. In this lesson students will investigate the inside of a cell.They will use their information to create a model of a cell, then persent it to class.

Software
Memo
Skethcy
Palm desktop

Technology
Computer
Power point

Objectives
TLW:
LS-M-A1
Observe and identify the basic componants of cells.
Identify the cell as the basic unit of structure and function of living things.
LS-M-A2
Compare functions of plant and animal cell organelles.
Construct and classify diagrams as plant or animal cells.
SI-M-A5
Developing models to demonstrate conclusions reached through investigations.

Procedures
Day One:
Prior to this lesson students should be familiar with characteristics of living things.
Discuss with the students that all living things are made of cells and the cell is the basic unit of structure and function of all living things. Tell the students that their task is to find out what parts are inside the cell and what job each part is responsible for.
Students will work in groups of four:
• Each group will be assigned two or three cell parts.(depending on the number of groups)
• The group will search for information about their cell parts.
• They are to take notes using memo on their handheld:
o The function of each part
o What each part looks like or resembles
o Where the part is located
o The type of cell that contains the part
• Each group will draw and label their parts using Sketchy.
• Once information is gathered, groups will exchange their information with each other by beaming.
• This will also be beamed to me and I will sync it to the palm desktop.
• I will create a power point presentation using their drawings and information (to save time). This will be used as a review on the parts of the cell and their function.
• After each group has collected all their information they will record it on a data sheet. This will be turned in with their cell model.
• Tell the students that they are to create a model of the cell. They will brainstorm what could be used for each cell part and bring these materials to class. They will write down their ideas on memo using their handheld.
Day Two:
• Each group will create a model of a plant or animal cell identifying what type of cell they made and label each part.
• Groups will record what material was used to represent the part and why on their data sheet. Ex- green button = chloroplast= because it is green (Data sheet will be turned in and graded)
Day Three:
• Groups will present their cell to the class and explain what material they used for each part.
• Using the power point presentation review the parts of the cell with the students.
• Later students will be assessed on identifying the parts of the cell and their functions.
