Unit 1 BILL Standards
Chemistry of Life
The following standards are everything that you should know for the next test. I’m giving this to you
now so you can be working on it over the next few weeks. You could probably even answer them in
class while we learn about it! So, answer these in your BILL book. Remember, be detailed when
answering and include any pictures or drawings if that will help you learn and remember the
information. You are basically creating your own study guide. The standards should be highlighted or
written in a different color pen.
This is due the day of your next test: September 24/25
