SNC 2P F 1. Note: Ionic Compounds atoms, collision, ionization by e- exchange so charge develops, bond together as opposites attract, become a neutral compound overall in chart show formulas that have subscripts, not charges 2. finish Activity: TRY THIS Ionic Compounds pg. 179 3. Physical and Chemical Change Lab write-up from first day – complete questions Hand in note with chart of results 4. Skills lab: mass and volume water, block, coinage metal R W Ionic Bonding: with worksheets B-R diagrams of atoms exchanging e Lewis Dot Diagrams cross-over rule for formula writing naming Pg. 178 - 183 Activity: TRY THIS Ionic Compounds - follow directions independently (chart, building) -leave chart at lab station for checking 1. 2. Complete chart of three more atoms ions OR Cut out puzzle pieces for “building” ionic compounds T 1. Lab: finish it & complete write-up on back 2. return B-R diagrams 3. new worksheet for Ion Formation with energy levels drawn in Enter NB data (atomic number, symbol, column number etc.) Do 5 selected atoms ions for marking & hand it in 4. Practice sheet: identifying physical vs just chemical change - give supporting evidence (observations) and conclusion - ex. melting physical change of state -hand in chart with 3 more ions -name on envelop of puzzle pieces -hand in lab sheet -hand in 5 B-R diagrams of ions -hand in practice sheet for physical M Return work: - classifying matter, physical properties, B-R diagrams *show two lists for p.p./ demo marking for B-R/ Improve/Complete 5 B-R diagrams for marks (title: Atoms) 2. Lab: Discuss -what to look for in each spot (note in test agent column) -importance of the size of the toothpick -use of white paper behind it to see Lab: finish as far as possible in last 15 – 20 min. F R W 1 .Note: Physical and Chemical Change -on handout PD Chemical Properties and chemical reactions 1.Try This pg. 176 for theory of ion formation -modify diagrams to show elements 2.Lab: Forensics – physical and chemical change -share chemicals from lab spots 2,4,7,9,12,14 -just do one run (one powder) Physical Properties -note on chart for physical/chemical, qual./quant. Do top section – classify one element in a T-chart (property/report) Do bottom section - viscosity race (order selves HLow for motor oil samples); test – classify one solution (honey, syrup, soap) T M Sept 12 1.Reviewed the TRY THIS pg. 164 – on overhead -phrase the trends together -leave last question to do 2. Atomic Theory – quiz/worksheet from gr. 9 (hand in for marks) 3. Classifying Matter: Elements and Compounds (models sheet) - draw oxygen in chart - use kits to build diatomic molecules (O, H, Cl, bonus N) F Sept 09 1. Self-test Classifying Matter vs chemical (highlight 5 that are correct for sure) -read pg. 169 on physical and chemical change -hand in B-R diagram sheet again -hand in lab observations sheet from lab 1-6 1,4,5 and viscosity R Setpt 08 W Sept 07 -empty flow-chart: add categories and classify 12 substances from samples on the lab counters 2. Periodic Table Assignment pg. 162 -areas, symbols, atomic numbers, element vs compound 3. TRY THIS pg. 164 -atomic structure of the first 20 elements -patterns on the periodic table 1. Lab feedback 2. Organize seating plan 3. Crossword Puzzle of Chemistry Review text sign out 4. Add to harmful chemical reactions note 6. Getting Started pg. 157 again, title, pg. date key words defined worksheet for atoms and elements? flow chart of matter 1. Rules: don’t touch anything & be nice 2. Seating, lab station, text book sign out, 3. Course handout, list of culminating tasks (3/4?), CHEMISTRY 4. Story: my niece and her cell phone (same details as Ivanna) Read questions 1, 2 and discuss them Note: Chemical Reactions, date, pg. 155 summarize nickel problem list other harmful effects of a) – d) 5. LAB: Go to lab desk and produce some chemical reactions worksheet, safety – lab glasses, wash up, perform, leave proof of work on the lab counter, complete chart at desk, return to clean-up, work together if you please but each does own write-up -classify 10 substances at lab counter (get 2 for each as examples) Intro. pg. 155 -test tubes (6) -rack (2) -chemicals in pill containers
