Do Now How do you cure a bacterial infection?

2. Activity 1 - Virus Brain Pop 3. Activity 2 - Vaccine Brainpop Aim: How can a vaccine help prevent a viral infection but not a bacterial infection? Agenda 1. Do Now 2. Activity 1 - Virus Brain Pop 3. Activity 2 - Vaccine Brainpop 4. Check for Understanding 5. Activity 3 - Discussion Questions 6. Activity 4 - HPV

Why is this important? In your lifetime you will be told to get vaccines through an injection. It is important to understand why we are putting these things into our body.

Activity 1 – Brain Pop – Viruses Directions: Watch the video silently. Answer questions 1-4 based on the Brain Pop video. Be ready to share out your answers. http://www.brainpop.com/health/diseasesinjuri esandconditions/viruses/

Activity 1 - Brain Pop Questions 1. What is a virus? 2. What does it need in order to reproduce? 3. How does the virus use the cell? 4. What are some examples of viruses?

Activity 2 - Brainpop - Viruses Directions: Watch the video silently. Answer the questions based on the Brain Pop video. Be ready to share out your answers. http://www.brainpop.com/health/diseasesinjuri esandconditions/vaccines/preview.weml

Activity 2 - Brainpop - Vaccines 1. What are vaccines used for? 2. How do antibodies and white blood cells fight pathogens? 3. Why can you only get the chicken box once? 4. What is in a vaccine? 5. How do vaccines work? 6. Why do you usually not get sick from a vaccine?

Check for Understanding 1. It is recommended that people at risk for serious flu complications be vaccinated so that their bodies will produce antigens to fight the flu virus antibodies against the flu virus toxins to fight the infection caused by the flu virus antibiotics to reduce symptoms caused by the flu virus 2. When a new viral infection appears in a population, scientists usually try to develop a vaccine against the virus. Which substances would most likely be contained in the new vaccine? live bacteria that ingest viruses white blood cells from an infected individual weakened viruses associated with the infection a variety of microbes that will attack the virus

Check For Understanding If you got 0 or 1 correct, use the powerpoint on the class website to assist with the discussion questions.

Discussion Questions 1. Explain the difference between bacterial infections and viral infections Your answer should include: antibiotics, vaccines, alive, host cell 2. Why can’t a viral disease be “cured” but bacterial diseases can? 3. Why is it that for certain viruses, you only have to get the vaccine once and your body will know how to fight off this disease and in cases such as the flu you have to get the flu shot every year? 4. Based on your knowledge of the immune system, do you think viruses or bacteria are more dangerous to your ability to stay alive? Why?

Activity 4 - HPV Directions: Using the transcript from the video and the interactive website, make an argument on HPV. Your answer should include: A claim, reasons, evidence from the transcript or website, counter-claim, conclusion sentence. Should states require mandatory HPV vaccines for students at public schools? https://platform.ilearnnyc.net/d2l/le/content/148000/viewContent/2007024 /View?ou=148000

Reminders

Immune System When first exposed to disease, organisms make specific antibodies to mark the foreign invaders so the white blood cells know what to destroy. If exposed to the same pathogen again, the immune system has a memory and can quickly make similar antibodies that will match the SAME antigens as the sickness from the previous time. REMEMBER: since Antigens and Antibodies are proteins that specific shape that match. SHAPE DETERMINES FUNCTION

Illness and Germs Pathogens is the term that refers to all germs and microbes that can cause illness in an organism?

Bacteria Bacteria are single-celled organisms. They are alive because they can carry out the characteristics of life without needing the help for another organism

Characteristics of Life Repair injury Reproduce Communicate Digestion/Excretion

Viruses Viruses are non-cellular (not a cell) They are dead because they cannot performs] the characteristics of life without having a host. The infects to cause illness and death.

Cures and Treatment Diseases caused by a bacteria can be cured because the bacteria can be killed. Doctors inject a person with antibiotics to kill the bacteria Viruses cannot be killed because they are NOT alive so there is NO cured for them Vaccines can PREVENT viruses from infecting organisms

Vaccines Vaccinations use dead or weakened microbes (virus) to stimulate the first production of antibodies They are not as strong as the disease so the person does not get sick Helps organisms build a memory of antibodies.

Vaccine Process A dead or weaken virus is injected into an organism The immune systems recognizes the virus and synthesizes antibodies The immune system makes a memory of the virus so when the real virus (not a dead or weak one) comes it can use the antibodies to stop it immediately.
