Thank you for not chewing gum!

1 March 25 th, 2015 What do I need today? 1. Pencil 2. Science Notebook 3. Epidemiology note sheet Learning Target: Today we will continue to learn about the fascinating world of disease and epidemiology by taking notes and discussing disease, bacteria and viruses. Daily Question: Thank you for not chewing gum! Today s agenda: 1. Bell work 2. Continue epidemiology notes Create a 3 column chart in your notes section of your notebook. (like the one below, only it needs to be much bigger) Infectious Unsure noninfectious

2 Epidemiology the study of the patterns, causes, and effects of diseases a scientist who studies diseases a disease that CAN be spread from one source to another. disease that CANNOT spread between sources. They are caused by genes, environment, lifestyle, or a combination of these factors.

11 Sorting Diseases Turn to the table you made in your notes Using the list of diseases on the next slide, identify each as INFECTIOUS, NONINFECTIOUS, or UNSURE. INFECTIOUS UNSURE NONINFECTIOUS

12 AIDS/HIV Cold Pneumonia Alzheimer s disease Diabetes Salmonella Asthma Influenza (flu) Strep Throat Breast Cancer Leukemia Tuberculosis Bronchitis Lung Cancer Whooping cough Chicken Pox Malaria Measles Cholera Mono Sickle cell anemia

13 NONINFECTIOUS ALZHEIMER S DISEASE ASTHMA BREAST CANCER DIABETES LEUKEMIA LUNG CANCER SICKLE CELL ANEMIA

14 INFECTIOUS AIDS/HIV CHICKEN POX COLD SALMONELLA MALARIA MONO INFLUENZA (FLU) STREP THROAT TUBERCULOSIS PNEUMONIA MEASLES WHOOPING COUGH BRONCHITIS CHOLERA

15 Virus vs. Bacteria MAKE THIS TABLE IN YOUR NOTEBOOK Bacteria Virus Living or Nonliving Definition Examples How it spreads

16 Bacteria Tiny, one-celled creatures Get nutrients from their environments in order to live In some cases that environment is a human body. Bacteria can reproduce outside of the body or within the body as they cause infections. Some infections bacteria cause include sore throats (tonsillitis or strep throat), ear infections, cavities, and pneumonia.

17 Not all bacteria are bad. Bacteria Some bacteria are good for our bodies they help keep things in balance. Good bacteria live in our intestines and help us use the nutrients in the food we eat and make waste from what's left over. Some bacteria are also used by scientists in labs to produce medicines and vaccines.

18 Virus vs. Bacteria Bacteria Virus Living or Nonliving Living! Definition Examples How it spreads

19 Virus vs. Bacteria Bacteria Virus Living or Nonliving Definition Living! Single-cell living organisms, most abundant living thing in the world, can be good or bad for humans Examples How it spreads

20 Virus vs. Bacteria Bacteria Virus Living or Nonliving Definition Examples Living! Single-cell living organisms, most abundant living thing in the world, can be good or bad for humans Strep, ear infections, pneumonia, staph infections How it spreads

21 Virus vs. Bacteria Bacteria Virus Living or Nonliving Definition Examples Living! Single-cell living organisms, most abundant living thing in the world, can be good or bad for humans Strep, ear infections, pneumonia, staph infections How it spreads Reproduces on its own

22 Microbe an extremely small microorganism too small to be seen by the human eye. Virus Bacteria

23 Need to be inside living cells to grow and reproduce. Virus Most viruses can't survive very long if they're not inside a living thing like a plant, animal, or person. Host: what a virus lives inside of

24 Virus When viruses get inside people's bodies, they can spread and make people sick. Viruses cause chickenpox, measles, flu, and many other diseases. Because some viruses can live for a while on something like a doorknob or countertop, be sure to wash your hands regularly!
