Standard B-2.1: Recall the three major tenets of cell theory
Standard B-2.2 : Summarize the structures and functions of organelles found in a eukaryotic cell (including nucleus, mitochondria, chloroplasts, lysosomes, vacuoles, ribososmes, endoplasmic reticulum [ER], Golgi apparatus, cilia, flagella, cell membrane, nuclear membrane, cell wall, cytoplasm).
1. Students will be reminded and be expected to know the content of the cell theory
2. Students will understand the difference between plant and animal cells and which organelles are present in which type of cell.
3. Students will create a memorable way to think of each organelle in the analogy activity.
4. Students will learn the organelles of the cell, what their role is within the cell, and how they function within the cell. Students will express their knowledge by a paired research project.
5. Students will be able to explain how the different organelles in the cell are connected. Students will do this by applying information gathered in the research activity to the Journey into the Cell activity.
Power point review of cell theory, the history of cell theory, and the scientists that discovered the cell and those who are credited with the cell theory.
Involve students by:
~Have students recall what unicellular and multi-cellular organisms are and give examples of each kind.
~Ask students to name the major cell structures of both of these organisms…should be reviewed from seventh grade.
~Ask them what the difference between plant and animal cells is in reference to organelles.
Show class the interactive web site CELLS alive! to demonstrate the difference between plant an animal cells. Allow them to lead you through picking which organelles they believe belong in the animal and plant cell. Website also shows the shape and size of the organelles in the cell.
Cells alive! does not have diagrams of flagella and cilia use power point to show how cilia and flagella move the cell and explain their importance. Show movie from Rowland Institute at Harvard for flagella movement and movie of cilia from U Mass Med.
Analogies and organelles- individual activity
An organelle will be given to each student. Two students should have the same organelle.
Each student will create a comparison between an organelle and something in everyday life.
In this activity your team will assemble and edit scientific information on cells, then write a creative story.
Decide what type of cell to write about within your group. (plant or animal) record on organizer sheet
Assign a section of the story to each member of your group. Sections are listed below
Discuss and outline your story (intro, body, conclusion) with your team. Remember to use the same character names and tenses in each section.
Begin researching and writing your story. Some materials you may want or choose to use are: Encyclopedia, text book, notes, research activity, Internet. (Remember the acceptable places to gather information from the Internet.) Record individual research on the organizer sheet.
After gathering information your team will come together to complete the planning page. The planning page will help you prepare to write and illustrate a creative story. Completing the worksheets will ensure a quality story. Use the planning page to create an outline and the organizer sheet to help you add facts to your story. (Don’t forget to cite your source.)
Title of Story: _________________________________________________________________
Each team member is responsible for WRITING about and ILLUSTRATING the 3 organelles listed under their SECTION. The organelles do not necessarily have to be discussed in that section. For example, your team may wish to discuss ribosomes, ER, and chloroplasts in sections 2 and/or 3.
P=plant cell organelle
A= animal cell organelle
Section 1 (introduction)
Describe the setting of your story. How did you get into the cell? What kind of cell are you in? What do you see around you?
P: cell wall, cell membrane, cytoplasm
A: lysosomes, cell membrane, cytoplasm
What is happening to you? Begin to develop the plot. What is it like to be inside of a cell? What is the focus of this story? Will you be trying to get out of the cell, or will something happen to you?
P/A:nucleus, chromosomes, nucleolus
Continue the adventure. How are you traveling around the cell? How are you reacting to what is happening inside the cell? How are the different cell parts reacting with you?
Section 4 (Conclusion)
Resolve the adventure. How will your story end? How will you leave the cell (if you do)? “Wrap up your story”
Use this page to help you organize what you know about an animal or plant cell. Be specific when recording your facts. You can elaborate on them when writing your story. (Each team member is responsible for 3-4 cell organelles and/or parts)
What parts/organelles are you responsible for?
Where are they located
What do these cell parts/organelles look like?
(type of cell A or P)
What are the functions of each cell part?
How does each of the cell parts/organelles work with other parts of the cell?
Each student will be evaluated throughout the lesson plan.
They will be evaluated on their understanding of the organelles in the analogy activity, their ability to conduct an information search and the relevance of information gathered during their search.
Students will be evaluated on their ability to apply gathered knowledge and their understanding of the structure and function of cells in the story activity.
This activity provides individual and team grades. Students will be graded individually on correctness of the information on the organelles they were responsible for and on the section of cell interaction they were responsible for. Students will be graded as a team for the content, flow, correctness, and relevance of their story.
