3. 4 th Period Quiz to be taken –Josh (DNA + retake Area of Science) –Estee –Ethan –Nevah (makeup Areas of Science quiz in SH)

4. Journal Entry #1 What kind of superhero would you be if you could genetically get superpowers? Why?

5. HONORS Let’s share the topics of the articles you found Genetic Mutations lead to a conjoined Snakes

6. Journal Entry Describe what it would be like to be a geneticist without the knowledge of DNA.

7. Journal Entry Why is it so important that cells divide?

9. Revisit DNA What is a chromosome? How would you describe the unique structure of DNA? What exactly is DNA replication? Most importantly…. Why is DNA called the “Blueprint of Life”?

10. Every cell in our body has the same DNA…specific to us! How do cells do that?? Cells double their genetic information through DNA replication, and then divide….resulting in 2 cells, exactly the same! This process is called MITOSIS. Why do cells divide? (why do we need MORE cells) –Organisms GROW... And need more cells. –Replace dead cells.

11. Mitosis Videos Watch the short videos of mitosis.

12. Mitosis Diagram Cut out the phases of mitosis and place them in order in your science notebook Use pages 58-59 in your textbook. Read about each phase and summarize the key facts about each next to the cut- outs on your poster.

Write the words on the left side Write the definitions or draw pictures on the right side. Use this tool to help you study

17. Warm-up Review the stages of mitosis. What stage are you? Why?

18. Mitosis Review What stage of mitosis is this in? ANAPHASE

19. Mitosis Review What stage of mitosis is this in? METAPHASE

20. Mitosis Review What stage of mitosis is this in? PROPHASE

21. Mitosis Review What stage of mitosis is this in? TELOPHASE

22. Cancer Understand it. Understand how to prevent it.

23. Where can you get cancer?

24. Read Articles and share Four articles are at your table… each person will become an EXPERT on that article – Read/Annotate/Highlight/Pre- Read Take note on your worksheet Share your information and teach the other people! Everyone should have the key parts of each article on your notes sheet when we are done

25. How to Pick out key points “Sharing in Short Hand” “Cancer is a disease in which abnormal cells are able to invade healthy tissue” “There are more than 100 different types of cancer” A Benign tumor is a tumor that is non cancerous, can be removed and does not spread to other parts of the body?

26. What is cancer? Cancer is a disease in which cells grow and divide uncontrollably (like weeds in a garden). Cancer damages the parts of the body around it. Cancer begins with a mutation in the DNA. A mutation is damage that causes a change in that individual’s specific genetic code.

27. Mutations Can begins when mutations disrupt the normal cell cycle, causing cells to divide in an uncontrollable way. Cells begin to grow too large, and divide too often. As more and more cells grow uncontrollably, the mass of cells becomes a tumor.

28. How does cancer spread? It can take years for a tumor to grow. As time passes, tumors become more and more abnormal. Sometimes cancer cells can break from the tumor. They may enter the bloodstream. Cancer can then be spread throughout the body.

29. Cancer Treatment Surgery: this is the best way to remove cancer from the body IF it has not spread to other parts of the body. Radiation: beams of high-energy waves that kill cancer Chemotherapy: use of drugs to treat cancer. Typically carried through the bloodstream- can kill cancer, or slow down cell growth.

30. Important Cancer Terminology Benign Tumor: a non- cancerous tumor that does not grow or progress. Malignant Tumor: a cancerous tumor that progresses in size and can be very potentially dangerous. Metastasis: the spread of disease from one part of the body to another.

31. There are many kinds, and causes, of cancer. Some cancers are heritable. Some are caused by lifestyle. Some people are born with mutations in their DNA that cause cancer. Other times a mutation occurs as a result of the environment, a disease, or the lifestyle of that person.

32. The bad news. In 2009 about 1.5 million people were diagnosed with cancer. In the US, cancer accounts for nearly 1 in every 4 deaths. Cancer is the 2 nd most common cause of death in the US. http://www.cancer.org/downloads/STT/500809we b.pdf

33. The good news. Many kinds of cancer can be prevented. If caught early on, it is possible to survive cancer through a variety of available treatments. Scientists know more about cancer than ever before- and believe that they will eventually find a cure. http://www.cancer.org/downloads/STT/500809we b.pdf

34. People young and old are affected by cancer. Skin cancer, lung cancer, and breast cancer are among the most common types of cancer found in adults. Leukemia, cancer of the bones or bone marrow, is the most common type of cancer found in children.

35. Live healthy! You can reduce the likelihood of getting cancer by taking care of your body! - wear sunscreen. - don’t smoke - eat right - stay active

36. Hope for the Cure Billions of dollars are spent on cancer research every year! Technology today is more advanced and better than ever. Doctors are increasing their knowledge of causes of cancer- increasing the public awareness on how to prevent it.
