8 th Grade Science Today’s Schedule 1. Do Now 2. Lab – Investigation of an Unknown Disease Essential Question Vocabulary Pre-APGrade-Level Infectious Disease Activity HW due on Friday How have diseases changed over time? How have the effects of disease changed over time? Prokarya Eukarya Plantae Animalia Archebacteria Eubacteria Fungi Protista Virus Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Today we will… Objectives: Students will graph statistical data from an epidemic, calculate attack rates, analyze graphical data, design an experiment to investigate the source of a causative agent of an epidemic, and compare the characteristics of known diseases with an unknown. Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Investigation of an Unknown Disease -Read the Background -Read the Situation Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Defining a Case - Formulate a working definition Which group of symptoms would you use to determine if a patient represented a “case”? Why would you not want to include a symptom such as “sore throat” in your definition? Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Making an Epidemic Curve - Make a histogram Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Determining Attack Rate - Attack rate is the proportion of the population that is at- risk for infection who actually develop the illness over a period of time. (Number of cases / Number of people exposed) x 100% What is the attack rate for the employees at the time of your arrival on Saturday? (show your work) What information must you have to determine an attack rate for the visitors? Why is it much easier to determine the attack rate for the employees than for the visitors? Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Continuing the Investigation (part I) What is the one thing that all cases appear to have in common? Formulate a hypothesis as to the source of the illness. Back it up with evidence that you have collected. Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Continuing the Investigation (part II) What does this information tell you about the transmission of the agent causing the outbreak? Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Continuing the Investigation (part III) How would you go about identifying visitors to the health center? Calculate the attack rate for visitors to the health department. (show your work) Why do you suppose that the attack rate is considerably lower for visitors than it is for employees? Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Continuing the Investigation (part IV) Revisit the epidemic curve (histogram) you began earlier. Add the new information to your histogram. Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Continuing the Investigation (part V) Are the epidemic curves for the employees and visitors the same? Give a possible explanation for this. You now suspect that you are dealing with something in the building itself that is causing people to become ill. What evidence points to this suspicion? Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Incubation Period and Source of the Disease (part I) About how long does it take someone to come down with the symptoms after being exposed? Based on this information in the table, which disease would you suspect as the culprit? However, based on the other evidence you have gathered, you choose to rule these out. Explain why. Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Incubation Period and Source of the Disease (part II) If your suspicions are correct, where would you expect the smoke to go? What types of samples would you want to take to try to identify the organism responsible for the outbreak? Suppose you had some lab animals available for testing the air conditioning system. Describe an experiment that you could perform to determine if the air conditioning system in the health department building is really responsible. Be sure to include replication and controls in your design. Wednesday & Thursday, May 15 & 16, 2013

8 th Grade Science Lab Incubation Period and Source of the Disease (part III) Suppose you had some lab animals available for testing the air conditioning system. Describe an experiment that you could perform to determine if the air conditioning system in the health department building is really responsible. Be sure to include replication and controls in your design. Wednesday & Thursday, May 15 & 16, 2013
