This document provides a lesson plan for a cell biology class. The class has 20 students between grades 10-11, with most being female. An analysis of learning styles found a mix of visual, audio, and reading learners. The lesson will use a smart board, videos, and experiments to teach students about cell size and surface area to volume ratio. Students will tweet about these topics and present comparisons of cells to other systems to evaluate their understanding.

1. Cell Unit Plan – Lesson 4(Day5)
Analyze the Learner
General Characteristics
The learners are comprised of 20 individuals ages 14 to 16. The gender of the class is mostly
female with 12 girls and 8 boys in the classroom. The ethnic background of the students is 7
African American, 1 Hispanic, 1 Asian, and 11 white. While 18 members of the class are in the
10th grade, 2 members are 11th graders who have to repeat this course because of a failing grade
previously.
Learning Styles
An in depth analysis has not been conducted on each student to determine their particular
learning styles, an effort has been made to provide for three major learning styles of visual,
audio, and reading. After students have been introduced to the material they will be required to
use the material in group and/or individual assignments.
Entry Level Competencies
The primary prerequisite for this class is to be in the 10th grade or above and have passed the
science class for grade 9. Basic competencies in computers, smart phones, tablets, etc. will be
necessary to complete assignments and view course materials. Peer assistance will be
encouraged for those who are unfamiliar with some or all of the technologies to be used.

2. State Objective
The students will be able to tweet in the class Twitter feed about the cell membrane after viewing
a teacher made video, YouTube videos, a class poster, and short Power Point presentaion with
80% accuracy.
Select Methods, Media, and Materials
Materials
 Smart Board
 Wood blocks
 Ruler
 Calculator or smartphone with calculator
 Poster
Media
 Twitter
 Facebook
 Wireless internet connection
 YouTube
 Podcast
Method
The method of instruction will be large group for the bell ringer activity. Students will be shown
a brief presentation on why cells are so small. Students will be broken into pairs to conduct an
experiment on surface area to volume ratio.

3. Students will also be provided a podcast to listen to outside of the classroom to further their
understanding or allow a student to receive the information they missed while out of class for
any reason.
Utilize Media and Materials
Preview the Materials
The YouTube videos will be screened before class to ensure it displays properly and for
appropriateness.
The class Twitter feed will be tested at the end of the preceding class to ensure students can post
to the feed as well as their ability to connect to the school’s wireless internet.
The class Facebook page will be checked daily to ensure information is up to date and that
students are using it appropriately.
The smart board will be tested ahead of class time in order to ensure its functionality.
Prepare the materials
The class Twitter will be set up in advance of the class.
The smart board will be tested ahead of class time to ensure functionality.
Wooden blocks will be counted to ensure there are enough for each group.
Enough rulers and calculators will be distributed once the number of groups are ascertained and
their needs.
Prepare the Environment

4. The front of the class room will be dimmed to aid the view of the smart board.
The chairs will be grouped to view the smart board.
Prepare the Learners
The students will be given an oral explanation of why the cell is so small and why their size is
important.
Provide the Learning Experience
The class room will be sufficiently dimmed to be able to see the smart board as well as any
students that require closer seating to be able to see the smart board.
Students will be provided with an example of how to calculate the surface area and volume of a
cube as well as their ratio.
Require Learner Participation
Large Group
 The class will be conducted so students will be presented with information about the
size of a cell and its surface area to volume ratio.
 Students will be encouraged to ask questions and provide their insight about the cell’s
size and its importance.
 Students will be need to measure the volume of each of their cubes and their surface
area and rank them in order of largest to smallest surface area to volume ratio.
 The cubes will be of varying sizes for each group to prevent copying of information.

5. Evaluate and Revise
The twitter feed will be used to evaluate each student’s general understanding of the course
material. The Twitter feed will also be used to provide a real-time analysis of the lesson plan to
address any questions and concerns students have during the activity. Students will be offered
extra credit if they tweet something as a suggestion for improvement of the lesson plan.
Students will be required to tweet about the cell size and the surface area to volume ratio at the
beginning of the next class session to demonstrate their understanding.
During the next class session students will make a presentation of their comparison of a cell
to any system or object of their choice as a final evaluation.
