Intermolecular Attractions in Liquids and Solids Voice Thread Assignment Standards:
C-3.1 Predict the type of bonding (ionic or covalent) and the shape of simple compounds by using Lewis dot structures and oxidation numbers.
C-3.2 Interpret the names and formulas for ionic and covalent compounds. C-3.3 Explain how the types of intermolecular forces present in a compound affect the physical properties of compounds (including polarity and molecular shape).
C-5.1 Explain the effects of the intermolecular forces on the different phases of matter. Groups must finish their post by Friday, December 5. Each student must respond to at least three of the Voice Threads via voice or typing. Directions: 1. Get with your partners and read about your assigned topic (see below for the 7 possible topics). Use your text, my PowerPoint notes, or search online for more information about your topic. 2. Go to www.voicethread.com 3. Look at some of the examples of Voice Thread (find Chicken Man art – done by LEMS students) 4. Create an account 5. Create a Voice Thread. Title it with Sullivan Chem as part of the name, then the topic (solids, metallic, etc.) 6. Find at least three pictures that represent your topic and upload them to a new Voice Thread 7. Find supporting documents and make comments via voice or typing to complete the assignment 8. Comment on three other projects, using the works “From this Voice Thread I learned…”
Each subcategory (letter) will receive a score between 1 and 5, 5 being excellent. Total points earned/total points available will be your score. Additionally, you will earn a point for each of the three comments. 1. Liquids a. Types of intermolecular attractions between molecules (explain each and give one example of a compound) i. Hydrogen bonding ii.Dipole-dipole iii.London dispersion forces
