Greetings! I’m excited that you are taking AP Chemistry with me this upcoming year. I’m assigning a few things to look over before school starts so we can hit the ground running when classes begin. I’m doing this because our time together is special and I don’t want to waste a second of it. It may not seem like it now, but you will thank me when we have more time at the end of the year to review for the AP exam! Fear not, all of this material you should have covered and be familiar with from your Chemistry I class. In case you forget, I will attach plenty of resources if you need help or get stuck.
You will need the online version of the textbook to complete the worksheets. You can go online and access a copy of the textbook using the following link.
Assignment
Textbook Review:
Read through each chapter in the textbook. As you read, there are several key ideas or practice problems that I want you to complete using the chapter as a guide. Please try the sample exercises on your own first before looking at how the problem is solved. There are often other ways to solve the problem other than the way the textbook does, so as long as you show your work and end up with the same answer, you will receive full credit. The questions are in order with the pages in the textbook to help you in completing the assignment.
Textbook Questions:
Complete the selected questions by writing your answers or showing all necessary calculations. For questions numbers that are blue, the final answers can be found at the end of the textbook. Please try the questions on your own before looking at answers. You must show all your work to receive credit. No work will result in a missed question.
Grades:
All textbook review worksheets AND textbook question worksheets will be due on the first day of school and will be counted as ½ of a test grade. You will take an AP level test on the first Friday of school over all the covered topics and the grade on that test will represent the other ½ of a test grade.
If you get stuck and have any questions or problems, please email me at. I check my email often and will get back to you as soon as I am able. It’s going to be a great year and I can wait to meet you! Remember Chem-Is-Try!
Sincerely,
Mr. Sox
