The Body's Defense System
The lesson consists of a series of mini-lessons presented through a PowerPoint presentation with embedded videos, formative assessments, a
simulation activity and a writing assignment that can be used as a summative assessment. The components of the lesson include the body's
external and internal defenses, information on the white blood cells role in defending the body and in creating immunity, vaccinations and how they
work to help produce memory cells and challenges to our immune system.

LESSON CONTENT
Lesson Plan Template: General Lesson Plan
Learning Objectives: What should students know and be able to do as a result of this lesson?
Students will:
1. identify the general functions of the integumentary system, circulatory system, and immune system of the Human Body in regard to Immunity and Defense.
(SC.6.L.14.5)
2. compare and contrast the Internal and External Defenses of the human body. (SC.6.L.14.5)
3. write an explanation on how our immune system works together to defend our body from pathogens using a minimum of two body systems. (LAFS.68.WHST.2.4)
Prior Knowledge: What prior knowledge should students have for this lesson?
Students should know:
the parts of the human body and how they function.
The systems of the body (circulatory, respiratory, skeletal, muscular, and digestive systems should be covered before starting this unit.
The basic function of the lymphatic and endocrine system is also necessary for understanding the immune system.
(The above topics are covered in Unit 7 of Florida's Science Fusion text. This supports the information in this lesson which addresses Unit 8: lesson 1 in the Florida's
Science Fusion textbook.)
Also covered in SC.5.L.14.1: Identify the organs and describe the functions of the human body.
Guiding Questions: What are the guiding questions for this lesson?
page 1 of 3 How does your body's defense system work? Should be asked after covering slides 4-6. the body has external defenses that help keep pathogens from entering the
body and Internal defenses that help our body eliminate the harmful pathogens. Should be re-asked after slides 9-12 to allow for more specific answers concerning
the white blood cells. Possible answers include: specialized white blood cells(T cells) attack and kill pathogens; some types of white blood cells (B cells) make
memory cells that recognize pathogens and attack quicker.
What changes (symptoms) happen to your body when you get sick? Should be asked when covering slides 4-6. Possible answers: Watery eyes and nose,
inflammation, fever, white blood cell count goes up.
How do the systems of the human body work together to allow the immune system to defend from pathogens? Should be asked at the end of the lesson and before
the writing prompt (Slide 18).
Circulatory: carries white blood cells to the scene of the infection
Lymphatic: Site of mature white blood cells (T-cells and B cells) that trigger the immune system and attacks invaders. Lymph fluid and nodes break down and
"clean" the blood of foreign particles.
Respiratory: External defense with mucus membrane. Also provides oxygen for the cells so the cells will have the energy they need to reproduce.
Skeletal: Blood cells are produced in the bone marrow.
Musculatory: Voluntary muscle movement pushes the lymph fluid through the body.
Skin is the first line of external defense for the body.
How does the body build immunity? Should be asked before and after slide 15. Natural Immunity happens when the white blood cells successfully defeat a pathogen
and memory cells are made. Vaccines are also given to increase immunity if a pathogen enters the body after a vaccination, memory cells identify it and the T cells
and B cells begin to attack the invader.
Teaching Phase: How will the teacher present the concept or skill to students?
The concept "Immunity" will be presented using a PowerPoint presentation. The opening of the lesson includes a short video with an interactive quiz on the immune
system (9 minutes). The presentation includes linked online resources, built-in quick assessments, and a link to a student simulation activity.
The students will complete sections in the Florida Science Fusion textbook as the information is presented in the PowerPoint.
Note: For teachers who are not using the Fusion Textbook, a guided notes worksheet is included in the Teacher resources andworksheets.pdf
Guided Practice: What activities or exercises will the students complete with teacher guidance?
1. The students will complete textbook pages in the Florida Science Fusion Text (or complete the guided notes worksheet) while watching the presentation.
2. The students will participate in several quick quizzes to check for concept understanding during the PowerPoint presentation.
3. The teacher will monitor Think-Pair-Share activities when asking for extended answers.
4. The students will perform a simulation of the binding between antigens and antibodies.
Independent Practice: What activities or exercises will students complete to reinforce the concepts and skills developed in the
lesson?
1. Students will participate in an on-line quiz to check for initial understanding.
2. Students will complete a Venn Diagram comparing External/ Internal Defenses.
3. Students will complete an exit card (or bellringer) reviewing class information.
Closure: How will the teacher assist students in organizing the knowledge gained in the lesson?
Students will complete a writing assignment to demonstrate knowledge of how the systems work together to defend the human body.
The students will be provided a rubric for the assignment.
Summative Assessment
If your district is using Florida's Science Fusion Sixth Grade, the summative assessments included in the program would be given (Lesson one Quiz, Benchmark
Review, and the unit test.)
A summative assessment for the lesson is also included on the PowerPoint as a writing assignment. A grading rubric is included.
Formative Assessment
The lesson is presented with a The ImmuneSystem.pptx. The show has built in assessment/activity slides. Information and ideas are included in the Notes portion of
the PowerPoint found with each slide. A combination of assessment activities are included. The attached Teacher resources andworksheets.pdf has detailed
descriptions, answer keys, and student worksheets to support the activities below:
1. Interactive on-line quiz after watching the introduction movie and a matching printable is also available.
The students can take the interactive quiz individually or the teacher can use the Thumbs up/Thumbs down method for a whole class method of formative
assessment.
The matching printable can be implemented individually or within small groups.
2. Role Play writing activity or Think-Pair-Share to describe the bodies external defenses.
3. Use a Venn Diagram to compare/Contrast External/Internal Defenses.
4. Provide an exit card to determine knowledge learned or use questions as a bell ringer to review previous day's material.
5. Simulation activity involving Antigen/Antibody connections.
This is a hands-on activity involving students using cardboard cutouts of antigens and antibodies to move around the room (human body) to find matching
pieces.
6. Thumbs up/Thumbs down quick quiz.
Feedback to Students
During the lesson, much of the student feedback is instant.
Examples of feedback would be:
The interactive quiz using either individual computers or the Thumbs up/Thumbs down method. The Think-Pair-Share would provide peer feedback and teacher
feedback when moving around the room.
The exit cards/bell ringer and Venn Diagram would provide delayed feedback. The information gathered from the written responses would need to be seen by the
teacher to determine if remediation is needed. The feedback would be written on the papers. A grade for correctness would not be assigned if the written activities
are being used as a form of formative assessment.
The simulation activity would provide automatic feedback as the "puzzle" pieces would not fit together if the Antigen/Antibody connection is not correct.
page 2 of 3 By providing this type of feedback, the students will have the opportunity to improve their understanding and score well on the summative assessment.
ACCOMMODATIONS & RECOMMENDATIONS
Accommodations:
The lesson is set-up to automatically accommodate students. The accommodations include the Think-Pair-Share segments, the on-line self quiz and the Thumbs
up/Thumbs down sections. These segments of the presentation will allow students to self-check. The exit cards and/or bell ringer will allow for the teacher to check
for understanding and be able to remediate students who need extra help. Students who need remediation will be provided additional information or help in a small
group setting.
Differentiation occurs due to the numerous types of activities included. The presentation hits several learning styles including:
the visual learner through the slides, videos, and images;
the auditory learner through class discussions and the presentation;
the kinesthetic and mathematical/logical learner through the simulation;
allows for social interaction during small groups;
and independent practice.
Extensions:
The Teacher Notes section of the PowerPoint includes articles pertaining to the lesson information on each slide. The articles could be used to incorporate reading in
the content area.
The students could create a "comic strip" to demonstrate the function of the white blood cells in the human body.
Suggested Technology: Computer for Presenter, Computers for Students, Internet Connection, LCD Projector, Microsoft Office
Special Materials Needed:
Cardstock or cardboard, large garbage bags, scissors for the Simulation activity
Printed copy of online quiz and matching activity
Printed copy of Venn Diagram from PowerPoint
Prepared Exit cards or Bell ringer activity
Further Recommendations:
Simulation activity: Time would be saved if the antigen/antibody pieces were prepared in advance.
