  1. Warm-UpFebruary 4, 2013 • Write down the date and objective. • Objective: SWBAT demonstrate understanding of Chemistry topics by completing the CMS Formative. • Complete the following warm-up: • What subatomic particle has to move from a higher to a lower energy level to emit light?

  2. Objective & Agenda • Objective: SWBAT demonstrate understanding of Chemistry topics by completing the CMS Formative. Agenda • Every Monday Matters • CMS Formative • Bohr Model & Electromagnetic Spectrum • Exit Slip • Homework

  3. Every Monday Matters • Eat HEALTHY

  4. FACTS • Annual cost for chronic conditions and diseases is big money: • $117 billion for obesity • $66 billion for high blood pressure • $432 billion for heart disease and strokes • $50 billion for weight-loss aids, diet foods, supplements, and weight-loss medications, yet obesity is still increasing

  5. FACTS • 79% likelihood exists that an overweight child will become an overweight adult • 75% of adults don’t eat the recommended daily 5 or more servings of fruits and vegetables • Snack consumption by children has increased 300% from 20 years ago. • 400,000 people die annually from poor eating habits and laziness.

  6. TAKE ACTION TODAY • If you suffer from or have a family history of any of the aforementioned chronic conditions or diseases, consult your family physician for dietary counseling • Although every individual is unique in his or her dietary needs, here are some ideas to help: • Eat fewer foods with refined grains and sugars; reduce your intake of fatty foods; and eat smaller portions • Eat more dark green vegetables, fruits, whole grains, low-fat milk products, and lean meats. • Eat slowly so that you will feel full before you’ve overeaten. • Don’t reward yourself or children with food. • Develop a routine and eat at similar times each day. • Drink plenty of water • Limit snacking. • Eat to live; don’t live to eat.

  7. YOU MATTER • You deserve to be in good health. For most, diabetes, hypertension, and other obesity-related chronic diseases are preventable by simply eating healthily and exercising. You will feel better than ever both mentally and physically- the only way to really live. If you don’t want to do it for yourself or your wallet, do it for those who love you. • Just start… one day at a time.

  8. CMS Formative • Silent Independence • NO ELECTRONICS! • Take your time and do your best • If you need something raise your hand • You have 45 minutes to complete the formative.

  9. Bohr Model Key points • Electrons exist in specific energy levels called quanta • When an electron moves to a lower energy level, light is emitted __ __ __ __

  10. Bohr model from reference table • When an electron falls from • n = 6 to n = 2, what wavelength of light will be emitted? • What is the region of the spectrum that corresponds to this wavelength?

  11. In nm: (700) (650) (590) (570) (490) (420) (400)

  12. When an electron falls from n = 6 to n = 2, what color of light will be emitted?

  13. Practice Problems • Complete the Bohr Model Practice Problems using the diagrams.

  14. Exit SlipFebruary 4, 2013 • If an electron in a hydrogen atom moves from n=4 to n=1 which type of light is emitted? • IR • UV • Red light • Blue light • No light

  15. Homework • HW 6- Electromagnetic Spectrum due Tuesday

  16. Honors Homework • Reading Assignment #3 • Read pages 98-104, #11-14, 18-20 • Read pages 328-330, #42-45 • Due Friday

  17. Reminders • Tutorials tomorrow after school
