Description of Unit

In this task, students will explore the physical and historical impacts of disease. Students will begin by researching cells, bacteria, and viruses and the role of each in the body. They will then study different diseases (e.g., common cold, HIV/AIDS, bubonic plague) and their impacts on the body. Students will then choose one disease and track its history through time. They will determine the impact on the populations (including future populations) affected, as well as the impact on lifestyles of affected populations (including future populations) throughout the world. 

This guide links the What’s the Diagnosis? task to the Texas Essential Knowledge and Skills (TEKS) for high school students. What’s the Diagnosis? is a science unit that allows students to explore the physical and historical effects of viruses and diseases. Though a science unit, What’s the Diagnosis? also helps students practice skills in the other subject areas of English language arts and social studies. For example, students will prepare, organize, and present informative and persuasive oral messages, which the English Language Arts and Reading TEKS address. They will also understand connections between major developments in science and technology and the growth of industrial economies and societies in the 18th, 19th, and 20th centuries, which the Social Studies TEKS cover. The following document includes the applicable TEKS and the details of What’s the Diagnosis? unit. The asterisks indicate the TEKS that are testable on the State of Texas Assessments of Academic Readiness (STAAR). The final section of this document presents the applicable Texas College and Career Readiness Standards adopted by the Texas Higher Education Coordinating Board (THECB) on January 24, 2008. 

Phase I. Learning Experiences

  1. Break up into groups. Have one group research cells, another research viruses, and a third research bacteria. Each group should present to the class their findings on what cells, viruses, and bacteria do to the body, what they are, and why they are present.
  2. Individually, or in small groups, assign each student a cellular or pathological disease. Students will research their disease and create a checklist for that disease as if they were a doctor examining a patient. Include symptoms/signs of the disease, drawings/pictures, and the body’s reaction to each stage of the disease (from onset until the end).
  3. Students will then have a class discussion about the diseases they studied and determine any similarities/differences that are significant, as well as any patterns that doctors, researchers, etc. would need to know to help distinguish the differences between cellular and pathological diseases.

Phase II. Independent Research

A. Research process

  1. Selecting a topic. Each student chooses one disease to determine the effects on the body, from onset to the end, as well as tracking the disease historically.
  2. Asking guiding questions. Once students have selected a topic, each student should think of three to five guiding questions, such as
    • How does this disease affect the body during each stage of its progression?
    • How have understanding and treatments of this disease evolved throughout history?
    • How has this disease impacted the affected populations and their lifestyles? Has it changed the lifestyles of unaffected populations?
    • How might this disease affect future populations and their lifestyles? What about the lifestyles of unaffected populations?
  3. Creating a research proposal. Students should identify their topic, guiding questions, and possible resources.  
  4. Conducting the research. After the teacher has approved student proposals, each student begins using the resources he/she has identified and others he/she may encounter. During this stage, the student will need to keep a log, note cards, and/or resource process sheets for all the sources he/she uses and what he/she learns from each one.

B. The product

  1. Students will make a formal presentation as if they are experts on the disease they researched and discuss its history, ways to fight the disease, what could hinder this progress, ethical issues in researching and fighting the disease, and economic impacts of the disease.
  2. Students will be given X amount of money in order to research the disease they have been studying. They will then discuss how they will spend the money and the details of their plans.

C. Communication (aligned with 1-2 above)

  1. Formal presentation, as if at a conference, which includes audience questions.
  2. Grant proposal that would be made to the agencies giving the money–should be persuasive. Include time for questions from the audience.

D. A completed project consists of:

  1. Research proposal
  2. Research log, note cards, and/or resource process sheets
  3. The product, including references or works cited
  4. A videotape or audiotape of the class presentation, including the Q&A session
