Waste Not, Want Not
Students will explore the excretory system through a variety of activities that include an inquiry lab, a reading excerpt, an engineering design
challenge, and creating an infomercial. Students will build a simulated kidney and explore what factors improve the filtering ability. Students will
analyze the data and formulate findings.

LESSON CONTENT
Lesson Plan Template: General Lesson Plan
Learning Objectives: What will students know and be able to do as a result of this lesson?
Students will be able to explain the concept of homeostasis in the human body through the function of the kidneys and the excretory system.
Students will be able to apply this understanding to creating a device that mimics the function of the kidney in removing waste.
Prior Knowledge: What prior knowledge should students have for this lesson?
Students should be able to identify the major organs of the human body, their functions, and which system they belong to.
Guiding Questions: What are the guiding questions for this lesson?
What is homeostasis?
Why is an understanding of homeostasis in the human body so important?
What is the function of the excretory system?
How do the systems of the human body work together?
page 1 of 3 Engage: What object, event, or questions will the teacher use to trigger the students' curiosity and engage them in the concepts?
Students will be shown a slide where there will be pictures of a diseased kidney and a healthy kidney. They will brainstorm and create a circle map on how this will
impact the human body and homeostasis.
Teacher's Probing Questions:
1. What is homeostasis?
2. How does the diseased kidney and the healthy kidney compare?
3. How will a non-functioning kidney impact the body over time?
Explore: What will the students do to explore the concepts and skills being developed through the lesson?
Part I: Guided Reading and Note-taking
A. The teacher will continue through the PowerPoint to review the function of the excretory system.
B. Students will read the article titled "The Excretory System," and then complete a tree map with the following headings:
1. Function
2. Ways kidneys remove wastes
3. How this system helps the body maintain homeostasis
Part II. Kidney Filtration Lab
A. Introduce students to the project. The students will complete the Kidney Filtration Lab.
B. Students will arranged in groups of 2-3.
C. Students will complete the Kidney Filtration Lab in order to explore how a normal functioning kidney removes wastes versus a non-functioning kidney remove
wastes from the body.
Part III. Engineering Design Challenge Portion
A. Students will design a filtration system that removes wastes from water while maintaining a specific volume and a specific rate of filtration.
Explain: What will the students and teacher do so students have opportunities to clarify their ideas, reach a conclusion or
generalization, and communicate what they know to others?
1. Students will complete a formal lab report in which they must collect data on volume and rate of flow from lab activities.
2. Students will complete an Engineering Design Planning sheet with an explanation and justification of each component of their creation to be included in their
filtration system.
Students should be able to demonstrate an understanding of:
the role of the kidney as a filtering system for blood
the by-products of the excretory system
the filtering function of a kidney on a larger scale
examples of filters designed by engineers, such as dialysis machines
Elaborate: What will the students do to apply their conceptual understanding and skills to solve a problem, make a decision,
perform a task, or make sense of new knowledge?
Students will create an infomercial in which they will be required to:
a. Demonstrate how to use their own kidney filtration assistive device (see attached)
b. Explain the importance of their invention for society
Summative Assessment
There are three activities that can serve as a Summative Assessment. Use any or all of these to have students demonstrate mastery.
Post test assessment (answer key included)
Engineering Design Challenge (rubric included)
Infomercial Project (Rubric included)
Formative Assessment
1. Tree Thinking Map; this will give you a good idea if students are organizing the material correctly
2. During the lab, ask students about the materials they are using and what they would represent in the human body
3. Post-lab questions are attached in the packet and follow:
1. What happened to the water while it passed through the different layers of the filter?
2. Compare the water filtered through each beaker. Is there a difference?
3. How is this activity like the action of the kidneys?
4. Why is filtering an important process in the urinary system?
5. How much waste were you able to filter for each level of functioning?
6. Compare the rate of flow for a kidney
Lab conclusion:
Describe in your own words how the kidneys filter waste from the human body, and how this helps to maintain homeostasis in the body.
page 2 of 3 Feedback to Students
The teacher should facilitate during the extent of this project. There are a variety of activities where students will be practicing what they learn: working on reading
and collecting information, listening and discussing what they are learning, thinking critically about what is happening in their lab, collecting data, analyzing data, and
using their creativity to design an infomercial. The teacher should ask the students questions to check for understanding, to keep them focused on the task at hand, to
redirect them, and to clarify what they are trying to say. The students will receive feedback all along the way during this project.
ACCOMMODATIONS & RECOMMENDATIONS
Accommodations:
Provide students a printout of the PowerPoint
Assign groups based on student needs
Reduce the requirements in the project if needed
Provide extended time if needed
Extensions:
Biotechnology or bioengineering is very closely related to this project. If your students are interested, you could provide them with information about the science of
synthetic organs by showing the video "Implantable Artificial Kidney May Cure Chronic Kidney Disease" uploaded to YouTube by SmartPlanetCBS's channel in order to
lead another discussion.
Suggested Technology: Computer for Presenter, Computers for Students, Internet Connection, LCD Projector, Microsoft Office
Special Materials Needed:
These materials are listed in the attached lab forms, and are also listed below:
Filter Paper
Cotton Balls (6 pieces)
Food Coloring
250 ml Beaker
3 Cups (Beakers)
Spoon
Water
Pencil and Paper
3 Funnels
Graduated Cylinder
Further Recommendations:
You could add other materials for the engineering design portion of the study that were not used in the inquiry lab if you wanted to integrate SC.6.L.14.6.
The teacher might want to assign diseases for each group to research, or provide a list of acceptable diseases to groups.

Description
Use variables to represent numbers and write expressions when solving a real-world or mathematical problem;
understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a
specified set.
Identify and investigate the general functions of the major systems of the human body (digestive, respiratory,
circulatory, reproductive, excretory, immune, nervous, and musculoskeletal) and describe ways these systems interact
with each other to maintain homeostasis.
