This collection of 367 documents contains everything a Chemistry teacher needs for the entire school year! Included are worksheets, labs, formative and summative assessments, lecture notes, weekly-pacing guides, and Powerpoint presentations that cover every single topic presented in a Chemistry course. These documents have been created and revised over the past 12 years to be as comprehensive as possible. Many worksheets come with complete answer keys, as well. These items have been used for all levels of high school Chemistry, including AP Chemistry, and undergraduate level General Chemistry courses. These can be tailored, as you see fit, for your own classroom. Many of these individual items are available from my store, as well, but this collection contains many additional items. Separately, these items would cost around $500, but the entire collection is MUCH less than that! I have tried to make it as easy as possible for a Chemistry teacher at any level to have access to everything they need to be successful! Before purchasing, please make sure that you have software that allows you to unzip this file. Enjoy :)
