GERMS: Keep Out!

  1. 2. <ul><li>Indicator 4.1.10 – Explain that if germs are able to get inside the body, they may keep it from working properly. Understand that for defense against germs, the human body has tears, saliva, skin, some blood cells, and stomach secretions. Also note that a healthy body can fight most germs that invade it. Recognize, however, that there are some germs that interfere with the body's defenses. </li></ul><ul><li>Taken from: </li></ul><ul><li>Link to activity: </li></ul>
  2. 3. <ul><li>Germ – A microorganism, especially a pathogen. </li></ul><ul><li>Pathogen —An agent that causes disease, especially a living microorganism such as a bacterium or fungus. </li></ul><ul><li>Sickness – The condition of being sick; illness. </li></ul><ul><li>Invasion –A large-scale onset of something injurious or harmful, such as a disease. </li></ul><ul><li>Saliva – he watery mixture of secretions from the salivary and oral mucous glands that lubricates chewed food, moistens the oral walls, and contains ptyalin. </li></ul><ul><li>Disease – A pathological condition of a part, organ, or system of an organism resulting from various causes, such as infection, genetic defect, or environmental stress, and characterized by an identifiable group of signs or symptoms. </li></ul><ul><li>Taken from: </li></ul>
  3. 4. <ul><li>Trillions of microscopic creatures, or microbes, are surrounding you right now. They are in your mouth, on your skin, and all over your body. Microbes can sometimes be good. They help you digest food and produce vitamins. But some can make you sick or even kill you. They are well known as germs. </li></ul><ul><li>Taken From: </li></ul>
  4. 5. <ul><li>In Greek, germs are called pathogens, which means the cause of disease. The four main types of pathogens are bacteria, viruses, fungi, and parasites. These pathogens have killed lots of people, more people than all of the people killed in all the world's wars combined.   </li></ul><ul><li>Taken From: </li></ul>
  5. 6. <ul><li>What makes a person sick? </li></ul><ul><ul><li>Germs </li></ul></ul><ul><li>How do you think germs enter the body? </li></ul><ul><ul><li>Broken Skin </li></ul></ul><ul><ul><li>Eyes </li></ul></ul><ul><ul><li>Mouth </li></ul></ul>
  6. 7. <ul><li>Students will explain that if germs are able to get inside the body, they may keep it from working properly and understand that if germs do get inside the body it has defenses against the germs. </li></ul>
  7. 8. <ul><li>Hold up an apple to the class. </li></ul><ul><li>Ask: “Is it possible that when this apple was growing on its tree, that it could have become infected by germs? How could the apple get an infection?” </li></ul><ul><li>Ask a volunteer to bite into the apple and hold it up to the class. </li></ul><ul><li>Ask: “Do you think germs would have had an easier time infecting the apple if its skin was broken?” </li></ul><ul><li>Discuss how the skin of an apple protects the apple much like the skin of a human protects the human from germs and disease. Once the skin is broken, it is easier for germs to get inside and hurt the body (and the apple). </li></ul>
  8. 9. <ul><li>Teacher Needs: </li></ul><ul><ul><li>Apple </li></ul></ul><ul><ul><li>Chalk </li></ul></ul><ul><ul><li>Chalkboard </li></ul></ul><ul><li>Students Need: </li></ul><ul><ul><li>Paper </li></ul></ul><ul><ul><li>Pencil </li></ul></ul><ul><ul><li>Copy of Black Line Masters ‘Tiny Invaders’ </li></ul></ul>
  9. 10. <ul><li>Tell students to think about a time when they were sick. </li></ul><ul><li>Inform students they are going to write a fictional or non-fictional story about such a time. </li></ul><ul><li>Distribute copies of the Black Line Master Tiny Invaders. </li></ul><ul><li>Tell students to answer the questions that are on the Black Line Master in their papers. </li></ul><ul><li>When finished writing their papers, have students share their stories with the class. </li></ul>
  10. 11. <ul><li>When I was seven years old, I got really sick at school one day. My teacher sent me to the office because she said I looked pale and thought I had a fever. The school nurse called my mom and she came to pick me up. My mom took me to the doctor and the doctor said that I had Pharyngitis. I had a really sore throat, was running a fever, and my nose was stuffed up. I probably got sick by other kids at school spreading germs. Sometimes people forget to wash their hands and then touch other people. That causes germs to travel from one person to another. Someone could have also sneezed around me, and I might have breathed in the ‘dirty’ air. The doctor gave me an antibiotic to get better. I got to stay home from school for three days, and then went back when I was better. </li></ul>
  11. 12. <ul><li>CONCLUSION: </li></ul><ul><ul><li>Allow each of the students to read their story to the class. </li></ul></ul><ul><ul><li>As a class, discuss ways to prevent germs from getting into the body. Talk about how we can prevent from getting an illness. </li></ul></ul><ul><li>4.1.10 SUMMARY </li></ul><ul><ul><li>Germs are able to get inside the body and may keep it from working properly. If germs do get inside the body it has defenses against the germs. </li></ul></ul>
