Course Description

This AP Chemistry course is designed to be the equivalent of the general chemistry course usually taken during the first year of college. For most students, the course enables them to undertake, as a freshman, second year work in the chemistry sequence at their institution or to register in courses in other fields where general chemistry is a prerequisite. This course is structured around the six big ideas articulated in the AP Chemistry curriculum framework provided by the College Board. [CR2] A special emphasis will be placed on the seven science practices, which capture important aspects of the work that scientists engage in, with learning objectives that combine content with inquiry and reasoning skills. AP Chemistry is open to all students that have completed a year of chemistry who wish to take part in a rigorous and academically challenging course. Big Idea 1: Structure of matter Big Idea 2: Properties of matter-characteristics, states, and forces of attraction Big Idea 3: Chemical reactions Big Idea 4: Rates of chemical reactions Big Idea 5: Thermodynamics Big Idea 6: Equilibrium

The labs completed require following or developing processes and procedures, taking observations, and data manipulation. See lab list provided for lab details. Students communicate and collaborate in lab groups; however, each student writes a laboratory CR2—The course is structured around the enduring understandings within the big ideas as described in the AP Chemistry Curriculum Framework. CR1—Students and teachers use a recently published (within the last 10 years) college-level chemistry textbook.

Post-Lab Work

8. Calculations and Graphs Students should show how calculations are carried out. Graphs need to be titled, axes need to be labeled, and units need to be shown on the axis. To receive credit for any graphs, they must be at least ½ page in size. 9. Conclusions This will vary from lab to lab. Students will usually be given direction as to what to write, but it is expected that all conclusions will be well thought out and well written. 10. Post Lab Error Analysis Questions Follow the same procedure as for Pre-Lab Questions. Advanced Placement Chemistry — The Laboratory Notebook A record of lab work is an important document, which will show the quality of the lab work that students have performed.
