Dec 6th 6:00pm Surviving and Succeeding: ❖ “Transfer theory” ➢ Retention through memorization ■ No critical thinking ■ No preparation ■ Temporary ❖ “Shaping Theory” ➢ Molded into a certain type of learner ■ Learner is unwilling to be shaped ❖ “Learning is a journey” ➢ Teacher is the experienced guide ■ Student may lack stamina ■ Student doesn’t trust the guide ■ Don’t trust the guide Tips: ❖ Come to class ❖ Pay attention ❖ Participate in groups ❖ Ask questions ❖ Come prepared ➢ Do the reading ➢ Knowledge builds on itself ❖ Attend office hours, visit SUPeR chemistry sessions ❖ Do not fall behind 1 What is Chemistry? ❖ The study of matter ➢ Its properties ➢ The changes it undergoes ➢ The e nergy ssociated with those changes Example: Balloon demonstration 1. Did a chemical reaction occur? a. Yes 2. What were the reactants? a. Hydrogen and heat 3. What were the products? a. Water vapor 4. Was energy absorbed or released? a. Released ❖ Matter: Anything that has mass and occupies space ❖ Energy: The ability to do work Adeline Fecker September 28th 2016 Use the Textbook effectively ❖ Use white space to summarize key points ❖ Pay attention to molecular depictions ❖ Do not skip over sample problems and follow up problems ❖ If you don’t understand something get help immediately Case of Medical Error: Example problems from the lecture slides 2 Adeline Fecker September 29th, 2016 The study of Chemistry is… ❖ Trying to make sense of macroscopic, observable in terms of submicroscopic unobservables ❖ Learning chemistry is learning to solve problems 3 *A number without a unit is meaningless* SI Base Units Via Pearson textbook Memorize: Giga, mega, centi, milli, micro, nano, pico Problem Solving ❖ Always show all your work GAME PLAN 1. Start calculation with the value that is known (DO NOT start with a conversion factor) 2. Use conversions to move from given unit to desired unit Given value and unit (desired unit/given unit) Volume: ❖ A derived unit Converting to volume 1L = 1dm³ 1mL = 1cm³ Density ❖ Fundamental physical property of substance 4
