                                     “It’s Not Just Water “


Grade Levels(s):       9,10,11,12, Occupational/Technical Health

Subject:               Science / Biology / Occupational Health

National Science Content Standards:
 Life Science, Cells – compare and contrast ways in which selected cells are specialized to
   carry out particular life functions (e.g., classifications by cell types such as red blood cells,
   white blood cells, muscle cells, etc.; specialized cell functions such as transport,
   photosynthesis, etc.)
 Life Science, Organization of Living Things – explain how living things maintain a stable
   internal environment (e.g., related systems/cells/chemicals – excretory system, circulatory
   system, endocrine system; factors/mechanisms under control – disease/infection,
   homeostasis).
 Life Science, Organization of Living Things – describe technology used in the prevention,
   diagnosis, and treatment of diseases (e.g., biochemistry; health monitoring activities)
 Physical Science, Changes in Matter – explain chemical changes in terms of breaking of
   bonds and the rearrangement of atoms to form new substances.
 Constructing New Scientific Knowledge, Design and Conduct Investigations using
   Appropriate Methodology and Technology – recognize and explain limitations of measuring
   devices; gather and synthesize information from books and other sources of information

Purpose:
1. To review the structure and function of the kidney.
2. To demonstrate to students the importance of Urinalysis as it relates to patient care.
3. To demonstrate to students how chemical and microscopic cell analyses relate to
    Urinalysis.
4. To introduce students to various urine abnormalities via case study presentations.
5. To introduce students to the roles of various clinical laboratory professionals.

Student Objectives:
Upon completion of the lecture presentation and laboratory analysis, students will be able to:
1. Describe the major functions of the kidney
2. List the major structures of the kidney involved in urine formation.
3. Describe the importance of performing Urinalysis.
4. Observe the various urine elements detected via dipstick chemical analysis.
5. Observe the basic cell types found in the microscopic analysis of urine sediment.
6. Name the clinical laboratory professionals who perform urinalysis testing and explain the
    education requirements of each.

Materials Needed:
1. Test tubes (plastic) and test tube rack
1. Mock urine samples (see Recipes section below)
2. Urine test strips (Bayer MULTISTIX® 10SG Reagent Strips for Urinalysis and product
    insert - available at local pharmacies or medical supply stores)
3. Handouts (provided in the Urinalysis Lesson section of the Teacher’s Toolkit):
     Urinalysis Laboratory Worksheets (includes answers and grading rubric)
     MULTISTIX 10SG Urinalysis Reagent Strip Information Sheet
5. Computer for “It’s Not Just Water” PowerPoint presentation and microscopic images.

Urinalysis Lesson Plan - “It’s Not Just Water “

Pre-requisites / Background Information:
1. Information presented in the lecture presentation titled “It’s Not Just Water”.
2. Teacher should review information in MULTISTIX product insert before Day 2 lab
     exercise.

Procedures – Day 1 – Lecture :
1. Lecture: Complete the pre-requisite background information presentation “It’s Not Just
    Pee”. (Approximately 45 minutes.)

Procedures – Day 2 – Chemical and Microscopic Analysis of Urine:
1. Divide students into groups of 2-4.
2. Distribute urine samples #1-4 and MULTISTIX® dipsticks to each group.
3. Distribute:
    a) MULTISTIX® 10SG product insert containing dipstick procedure and
    b) MULTISTIX® 10SG Test Strip Information handout.
4. Have students perform visual dipstick analysis on each urine sample and record results
    on their worksheet.
    NOTE: Stress the importance of proper read times for the different test areas.
5. Have students view microscopic images from each sample on the computer and record
    their observations on their worksheet. (NOTE: Microscopic images are provided at the
    end of the “It’s Not Just Water” presentation.)

Grading Rubric:
1. Correct performance of urine dipstick analysis                              30 pts
2. Neat completion of dipstick analysis worksheet for all five samples         30 pts
3. Correct results for each urine sample (N=4)                                 20 pts
4. Correct identification of microscopic cells for each sample.                20 pts
5. EXTRA CREDIT: State possible clinical conditions for each sample.           (10 pts)
6. Grade = Total Points / 100

Mock Urine Recipes (can be made up the day before and refrigerated):
1. Sample #1: 14 year old girl with thirst and fatigue - Mountain Dew (flat)
2. Sample #2: 85 year old man with kidney stone – 100 mL of chicken broth ( or one cup
    cooled chicken bouillon made with a bouillon cube or powder) with just a few drops of
    blood from raw ground beef or turkey added
3. Sample #3: 18 year old female with urine frequency – 5 mL (1 teaspoon) of ½ percent
    milk added to 45 mL water or bouillon.
4. Sample # 4: 16 year old male undergoing sports physical – chicken bouillon
