– BALANCING EQUATIONS Teacher: Course: HOFSTRA CHEMISTRY (B) Stage 1 – Desired Results Established Goals: Order in the universe is exhibited through the balance of masses in chemical reactions that allow life to function. Understandings: Students will understand that… Essential Questions: - applying the conservation of matter will balance on the universe if balance were not maintained? simple chemical equations. What sort of impact do you think it would have - properties of the reactants and products will aid in distinguishing between chemical and physical changes in a reaction process. - predicting single replacement reactions. Students will know… Students will be able to … 1. - write equations describing chemical reactions using appropriate symbols. 2. - write balanced chemical equations when given the names or formulas of the reactants and products in a chemical reaction. 3. - identify a reaction as combination, decomposition, single-replacement, double-replacement, or combustion. 4. - predict the products of combustion, decomposition, single-replacement, double-replacement, and combustion reactions. 5. - write and balance net ionic equations. 6. - use solubility rules to predict the precipitates formed in double-replacement reactions Stage 2 – Assessment Evidence Performance Tasks: Other Evidence: Final test consisting of matching, multiple Bell – ringers choice, short answer and mathematics. Home work Verbal responses to questions in class Food project at home. Quizzes Exit slips – BALANCING EQUATIONS Teacher: Course: HOFSTRA CHEMISTRY (B) Stage 3 – Learning Plan Day 1 Objectives: 1,2 Teaching Strategies: Go over any questions the students may have on naming & writing formulas. Handout unit 8 homework packet Give notes from the beginning through balancing chemical equations Have them work on homework problem # 1 after going through several examples with them. Resources: Homework packet for unit 8, with the answer key pre-made, Test answer from unit 7, notes Homework: finish homework problem # 1 before class. Day 2 Objectives: 3,4 Teaching Strategies: Have the students work on the balancing equations worksheet after answering questions from the homework assignment. Have the students work on the word equation sheet, which should be on the backside of the previous worksheet. Give notes on types of reactions Khan Academy Video Handout the blue worksheet for a partner quiz Resources: blue and green worksheet with the answer key, notes, Khan academy video keyed up Homework: finish the quiz if there is not enough time in class Day 3 Objectives: 4,5 Teaching Strategies: – BALANCING EQUATIONS Teacher: Course: HOFSTRA CHEMISTRY (B) Handout progress reports to let the students know what work they need to make-up Oreo cookie project (due test day – 5 school days from now) Notes on the type of reactions as well as equations Have the students work on the homework packet Resources: notes, progress reports Homework: answer as many of the questions in the homework packet as possible # 2 & 1-4. Day 4 Objectives: 5,6 Teaching Strategies: Collect homework problems #2 & 1-4 Review types and balancing equations Have the students work on the purple worksheet Hand out the quiz and allow them to work with a partner. If time allows and it is not full, allow the students to go through the marines obstacle course set up in the gym. Let the students know there will be a lab tomorrow Resources: purple worksheet and partner quiz with the answer key. Prelab information for the rocket lab, set up the rocket lab. Homework: Purple worksheet if they did not finish it in class. Day 5 Objectives: All Teaching Strategies: Rocket lab Resources: lab equipment and material Homework: finish the lab questions, study for the test. Day 6 Objectives: All Teaching Strategies: Review for the test in the test format by using the unit 8 test review Resources: Unit 8 test review with answer key Homework: Study for the test – BALANCING EQUATIONS Teacher: Course: HOFSTRA CHEMISTRY (B) Day 7 Objectives: All Teaching Strategies: Due to Christmas concerts by the choir and band we had to do another day of review. Resources: none Homework: study for the test Day 8 Objectives: All Teaching Strategies: Review for 10-15 min. Test Resources: test with answer key Homework: Read chapter 9 sections 1 & 2 outline and take detailed notes on this information.
