10.06 D5 Atoms Elements Molecules Compounds

  1. 1. Day 5: October 6/7 <ul><li>Objective: SWBAT define and diagram atoms, elements, molecules and compounds. </li></ul><ul><li>Homework: Complete Independent Practice on pg 31 wksht </li></ul><ul><li>Warm up: Jupiter has no solid surface. What do you think it is made of? </li></ul><ul><ul><li>Hydrogen and helium, which are elements </li></ul></ul>
  2. 2. Agenda <ul><li>Intro and guided practice – 20 minutes </li></ul><ul><li>Groups: Science Article – 50 minutes </li></ul><ul><li>Group presentations -- 10 minutes </li></ul><ul><li>Independent Practice – if done early </li></ul>
  3. 3. Let’s roll <ul><li>Everything is made of parts, and the parts have names. The parts together give the object its identity. </li></ul><ul><li>Think about a deck of cards </li></ul>Random piece of paper This paper Is a card The card is one of two colors 14 cards put together make a suit Four suits put together Deck of cards The card is one of 14 values
  4. 4. Page 31 <ul><li>Title: Atoms, Elements, Molecules and Compounds </li></ul><ul><li>(you will need to make questions and a summary AT HOME and it will be checked) </li></ul>
  5. 5. Atom <ul><li>Smallest unit of matter </li></ul><ul><li>Can not be divided </li></ul><ul><li>Contain electrons, neutrons and protons </li></ul>
  6. 6. Element <ul><li>A particular type of atom </li></ul><ul><li>Determined by the number of PROTONS (atomic number) </li></ul><ul><li>Can not be broken down into another substance </li></ul>B R
  7. 7. Molecule <ul><li>Two or more ATOMS </li></ul><ul><li>In a specific arrangement </li></ul><ul><li>Can be broken down into individual atoms </li></ul>B R B R B R B R You can draw these in a straight line for your notes like R – R – B NOT the same molecule!!!
  8. 8. Compound <ul><li>Two or more ELEMENTS </li></ul><ul><li>In a fixed ratio </li></ul><ul><li>Can be broken down into molecules or elements </li></ul>B R B R B R B R Same compound R 2 B
  9. 9. Guided Practice <ul><li>Draw one atom of “Blue” </li></ul><ul><li>Draw one molecule of “Green” </li></ul>B G G
  10. 10. Guided Practice <ul><li>What would a molecule of “Blue – Red – Blue” look like? </li></ul><ul><ul><li>only this </li></ul></ul><ul><li>What would a compound B 2 R look like? </li></ul>B R B B R B B R B B R B
  11. 11. Science in the News <ul><li>You will work in groups to read and process the article about mercury polluting the atmosphere </li></ul>
  12. 12. Framing questions <ul><li>What qualities of scientific investigations are revealed in the article? </li></ul><ul><li>What questions come to mind about the investigation? </li></ul><ul><li>What evidence supports the new scientific ideas presented? </li></ul><ul><li>What evidence or supporting arguments seem to be missing? </li></ul><ul><li>What kinds of data are discussed or presented (e.g.,  measurements, tables, graphs)? </li></ul>
  13. 13. Hints <ul><li>Remember, the point of investigating this is to focus on mercury </li></ul><ul><li>If you’re group is not talking about mercury, then you’re not on the right topics </li></ul>
  14. 14. Outcomes from group <ul><li>Poster depicting CFL use and whether or not it is a good thing in Missouri. </li></ul><ul><li>Make an advertisement type poster (like a stop smoking poster) </li></ul><ul><li>You should summarize on the poster why you are taking a certain position. </li></ul><ul><li>Remember, base your opinion on the issue surrounding mercury pollution </li></ul><ul><li>Any of the group members can be called on to present </li></ul>
  15. 15. Poster assignment <ul><li>Would you recommend a friend to use CFL bulbs? Why or why not based on evidence from the article about mercury pollution. </li></ul><ul><li>Create an advertisement-style poster </li></ul>
  16. 16. Independent Practice <ul><li>Start now </li></ul><ul><li>Work independently </li></ul><ul><li>Use the real elements </li></ul><ul><li>Check periodic table for correct symbols </li></ul>
