I was out today, but students were given a sheet of problems to practice working with the Specific Heat Equation. The lab handout for next week (Tuesday) was distributed and students had the opportunity to watch the Calorimetry Activity - Prelab Briefing on EDpuzzle; this must be viewed prior to Tuesday or student's will not be permitted to participate in class and will need to makeup the lab within 2 days.
Today we wrapped up our look at the class responses to the Changes & Properties surveys. An interesting takeaway was how changes that involved a disappearance of material (dissolving, evaporating) were frequently thought of as chemical changes. After we tackled this misconception, students followed up last night's EDpuzzle video on energy unit conversions with a sheet of practice problems.
Following today's Element Quiz #5 (don't forget, the Test on the entire Element Symbols packet is next Wednesday), please apply your knowledge and understanding of chemical and physical changes to the examples below.
Next, please apply your knowledge and understanding of chemical and physical (both intensive and extensive) properties to the examples below. We will have a class discussion about the answers.
Element Quiz #4 & then opportunity to ask questions that might appear on tomorrow's unit test on Math Skills for Chemistry.
Today we continued the station rotation activity, and discussed conversions involving squared and cubed units (see EDpuzzle for related video).
The PhET Density Simulation activities were also returned and some key points were shared.
Element Quiz #4 (Metalloids & Nonmetals) is tomorrow, as well as time to ask questions in preparation for Friday's Unit Exam.
This area will contain an overview of what was discussed/performed each day in class.
