Standards:
SPS1 Students will investigate our current understanding of the atom. b. Compare and contrast ionic and covalent bonds in terms of electron movement SPS2 Students will explore the nature of matter, its classifications, and its system for naming types of matter. b. Predict formulas for stable binary ionic compounds based on balance of charges. c. Use IUPAC nomenclature for transition between chemical names and chemical formulas of * binary ionic compounds (containing representative elements) * binary covalent compounds (i.e. carbon dioxide, carbon tetrachloride). d. Demonstrate the Law of Conservation of Matter in a chemical reaction. Wednesday: Quick review of Unit 2. Choose one formula to write and one compound to name (use the naming compounds sheet!) from the test on writing formulas and naming compounds. Find one other person in the class that chose different ones to answer and peer check. Watch a short animated video about classifying chemical reactions. Discuss the four basic types of chemical reactions: Synthesis, decomposition, single displacement and double displacement. Using the Physical Science Course Outline, create some goals. Read over the lab instructions for tomorrow. Thursday: Complete a modified version of a lab from Interpreting the Periodic Table. Perform the experiments in small groups and record observations in the lab table provided. Discuss and complete the post lab questions. Needed per group: 24-well microplate, weighing dish with 2 1-cm strips of magnesium ribbon, weighing dish with 2 2-cm2 squares of aluminum foil, weighing dish with 2 small pieces of calcium, weighing dish with copper shot, pipet, thermometer, white paper, beaker of water, bottle of HCL, forceps, goggles. Friday: In small groups, create a borax snowflake. Each group will have a different amount of borax to dissove into the hot water. There is a table to fill out for this. We will continue this on Monday. Watch the United Streaming video, Physical Science Series: Chemical Reactions and complete the chart in small groups. http://sciencespot.net/Media/ChemReactionsWkst.pdf
