SUMMER REVIEW

Mrs. Coronado Name:____________________________________

IB Chemistry SL 2018-2019

Prior to beginning the year of IB Chemistry you must complete the following exercises in review

from your past experiences in Chemistry. The week that students return to classes for the 2018-2019

school year a quiz will assess your prior knowledge. Students are required to have this assignment

completed AND pass the quiz. Students are encouraged to retain materials from past chemistry courses

in order to aid in their preparation for higher level content seen during the upcoming school year. It is also

encouraged that this review be completed in small portions throughout the summer vacation and not all in

one night the day before classes resume.
