Presentation Transcript

  1. 6.6 Aging and Skin Cancer 2.1 Atoms, Ions, and Molecules Sponge: Set up Cornell Notes on pg. 37 Topic: 6.6 Aging and Skin Cancer Essential Questions: What is the most common type of skin cancer? WHO is most likely to develop this cancer? What is the most common type of skin cancer? WHO is most likely to develop this cancer? • Put HW in pile at table • Get papers in tray

  2. Objective Students will understand the life-span changes in the integumentary system Students will create a tree-map classifying two types of cancer using Clinical Application 6.1 as a source

  3. Life Span Changes • Why are we more aware of aging-related changes in skin than in other organ systems? • We can easily see them • Aging affects appearance

  4. Life Span Changes Aging skin affects appearance, temperature regulation, and vitamin D activation

  5. Whiteboards!!! • One per table

  6. Life Span Changes- Epidermis • Epidermis: • BECOMES THINNER • Epidermal cells grow larger and irregular in shape • Skin may appear scaly • Age spots or liver spots appear/grow (due to oxidation of fat)

  7. Dermis: • BECOMES THINNER • Less collagen • Loss of fat • Sagging and wrinkling of the skin • Delay of wound healing Life Span Changes-Dermis

  8. Life Span Changes-Accessory Structures • Accessory Structures: • Hair: • Melanin production slowsWhitens • Hair follicles decrease in #Hair thins • Skin color: • Fewer blood vessels underlying the skin pale appearance

  9. Life Span Changes-Accessory Structures • Accessory Structures Cont’: • Nails: • Diminished blood supply impairs growthDull /harden • Oil glands: • Decrease oil productionDrierskin • Pain/Pressure Receptors: • #s Decline Less sensitive

  10. Life Span Changes-Accessory Structures • Accessory Structures: • Temperature Regulation: • Ability to shiver + sweat declines Less able to tolerate hot/cold • Due to hair follicles shrinking/ sweat gland #s decreasing

  11. Life Span Changes • What types of changes have you observed as people get older for: • Posture • Height

  12. Life Span Changes-Accessory Structures • Vitamin D production: • Vitamin D production goes down Loss of ability to maintain bone structure • Must take vitamins

  13. P. 36 Clinical Application 6.1 1. Fill out your tree-map on p. 36 of your notebook using your Clinical App as a source Skin Cancer Cutaneous Carcinomas Cutaneous Melanomas • Type of cells it arises from • Age range usually affected • Skin color usually affected • Type of sun exposure associated with each • Place(s) on body most commonly found • Describe its growth pattern • Treatment options • 2. Read and Highlight the CDC’s “A tan is not a sign of health” Latin– Cutis= skin Greek- Karkinoma= crab “creeping ulcer” cancer Greek- Melan= black

  14. 6.6 Aging and Skin Cancer 2.1 Atoms, Ions, and Molecules Sponge: Set up Cornell Notes on pg. 37 Topic: 6.6 Aging and Skin Cancer Essential Questions: What is the most common type of skin cancer? WHO is most likely to develop this cancer? What is the most common type of skin cancer? WHO is most likely to develop this cancer? ALREADY SET-UP Reminder: Clinical Apps signed tomorrow

  15. Objective Students will understand the types, causes, signs and treatment options for skin cancer With their group, students will create a poster about their assigned type/aspect of skin cancer

  16. Skin Cancer Posters • Need: • Answer all aspects of prompt • CLEAR HEADINGS + subheadings • Illustration(s) • Members name’s on BACK • 1 Chromebook per person Prompt is taped on each table

  17. 6.6 Aging and Skin Cancer 2.1 Atoms, Ions, and Molecules Sponge: Set up Cornell Notes on pg. 37 Topic: 6.6 Aging and Skin Cancer Essential Questions: What is the most common type of skin cancer? WHO is most likely to develop this cancer? What is the most common type of skin cancer? WHO is most likely to develop this cancer? ALREADY SET-UP Put Clinical Apps in a pile in the middle of the table

  18. Objective Students will understand the types, causes, signs and treatment options for skin cancer With their group, students will go on a gallery walk and take notes on the types/aspects of skin cancer

  19. 6.6 Aging and Skin Cancer 2.1 Atoms, Ions, and Molecules Sponge: Set up Cornell Notes on pg. 37 Topic: 6.6 Aging and Skin Cancer Essential Questions: What is the most common type of skin cancer? WHO is most likely to develop this cancer? What is the most common type of skin cancer? WHO is most likely to develop this cancer? ALREADY SET-UP

  20. Objective Students will understand the types, causes, signs and treatment options for skin cancer Students will: participate in a whole class review of skin cancer and work on their notebook checks/study guides

  21. P. 37 Skin Cancer Skin Cancer begins when UV radiation mutates the DNA of a skin cell

  22. The type of skin cancer is named by where it ORIGINATED in the skin: • Squamous cell carcinoma originated in the SQUAMOUS cells of epidermis • Basal cell carcinoma originated in the BASAL layer of the epidermis • Melanoma originated in the MELANOCYTES Skin Cancer

  23. Cutaneous Carcinomas • Arise from NON-PIGMENTED epithelial cells • Squamous cell carcinoma • Basal cell carcinoma • Cutaneous Melanoma • Arise from PIGMENTED cells (melanocytes) • Melanoma Skin Cancer

  24. Clinical App 6.1 : Cutaneous Carcinomas • Cutaneous carcinomas are skin cancers originating from the epithelial cells • Most common type of skin cancer • Occur most freq. in light-skinned people over 40 yrs old • Usually appear in people who are regularly exposed to sunlight • Most often on head, neck, face, scalp

  25. Clinical App 6.1 : Cutaneous Carcinomas • 2 types: • Basal cell carcinoma • Squamous cell carcinoma • Typically SLOW growing • Treatment is usually surgical removal or radiation treatment

  26. Clinical App 6.1 : Cutaneous Melanomas • Cutaneous Melanomas arise from melanocytes • Seems to be caused by short, intermittent exposure to high-intensity sunlight • People of ANY age may develop • Appear most often in the skin of the trunk, back, and on limbs

  27. Clinical App 6.1 : Cutaneous Melanomas • Surgical removal during horizontal growth can take care of the cancer • But, once the legion thickens and spreads into deeper tissues, it becomes more difficult to treat, and the survival rate is very low

  28. Objective Students will understand the types, causes, signs and treatment options for skin cancer With their group, students will create a G. Slides presentation about their assigned type/aspect of skin cancer

  29. Skin Cancer Project Grouping • You will be working on a Skin Cancer Research Project • 9- 10 groups (depending on period) • Need to decide grouping today—divide work up • Due end of period MONDAY • INFORMAL PRESENTATIONS on TUESDAY P1: 7 groups of 4 + 2 groups of 3 = 34 P2: 9 groups of 4= 36 P3: 8 groups of 4 + 2 groups of 3= 38 P5: 8 groups of 4 + 2 groups of 3 = 38

  30. Day 1 As a group you will design a Google Slide presentation to educate the class on a particular topic related to skin cancer. • Groups assigned by # (1-10) • Planning/Research • Only one person in the group will submit the project • Submit MON by – END OF PERIOD PRESENTATIONS ON Tuesday--- 3-5 min presentations

  31. Day 2 As a group you will design a presentation to educate the class on a particular topic related to skin cancer. • Work on Google Slide Presentation

  32. Day 3 As a group you will design a presentation to educate the class on a particular topic related to skin cancer. • Work on Google Slide Presentation • Turn into Google Classroom under 1 person’s name by the END of the period • Must be in Google slides

  33. Skin Cancer Presentations As a group you will present your G. Slide presentations to educate the class on a particular topic related to skin cancer.

  34. Skin Cancer Presentations • Turn in rubric WITH ALL MEMBER’S FIRST AND LAST NAMES • Get out a clean sheet of notebook paper: • # Groups 1-10 • Something positive • Something more critical • Something you learned • Clear desks of ALL other materials • Notecards OK

  35. A Tan is not a sign of health UV Bead Activity--- “The beads help kids from kindergarten to high school see right away that ultraviolet light rays may be invisible and impossible to feel, but they exist and can damage your skin regardless of color” Ex: Bob Marley died of melanoma

  36. Taping Time (if time) 28: Layers of the skin ½ sheet 30: Clinical App 6.2-6.3 32: WebMD- Hypothermia/ Children die after being left in hot car 34: Body Story Video Questions 40: Skin Deep/ Global Map of Indigenous Skin Colors/ The Human Spectrum Web Activity 42: (CLINICAL APP 6.1 will go here)

  37. UV Bead Activity

  38. UV Light • Read the background on UV light • Highlight important details • Fill out the prediction portion on the back of your sheet • Come up with 5 tests of your own

  39. UV Light • Get in pairs • Each pair gets 3 beads • Test as many scenarios as possible • Choose 5 of your own • Answer the questions on the bottom
