Engaging Strategies: Activities: 1. Lab Report – Conductivity of Solutions 2. Lab – Comparing Ionic and Covalent Compounds NO HANDOUT a. Students are melting Rock Salt and Para dichlorobenzene in an evaporating dish, to compare the strength of Ionic and covalent bonding. b. Students are measuring violality and solubility of Rock Salt and PDB. Directions for students: At the lab stations you will find the tools need to conduct a test on the melting points of rock salt and moth ice crystals. You task is to conduct an experiment that is viable and repeatable. To do this, you will need to write down every step you took and every measurement you took explicitly. You will not have a thermometer, but you will have a stop watch. Pass the temperature on the time, every 5 seconds of heating in a 3 degree Celsius increase, starting at 20 oC. Summarizing Strategies: Materials: Rock Salt, Moth Ice Crystals, Bunsen Burners, Lighters, Ring stand with ring, wire mesh, evaporating dish, Crucible tongs, test tubes, goggles and aprons, stop watches, Lap Report (Blank). Homework: Complete the Guided Reading through section 4.2 Day 5 Essential Question: What do Chemical Formulas and Naming mean? Engaging Strategies: Summarize the data found from yesterday’s lab, describing the properties of Ionic and covalent bonds in terms of the parameters investigated in the lab yesterday. Activities: 1. Discussion of yesterday’s lab 2. Lecture 4.3 – Compound Naming a. Using my handwritten notes b. Students to take their own notes from the board. 3. Practice Worksheet – Naming Ionic compounds, ALL four parts 4. When finished with previous worksheet, work on homework. Summarizing Strategies: Ionic Compound Worksheet.
