Basic Chemistry Scavenger Hunt

Each of you comes to this class with certain amount of knowledge concerning Chemistry. This scavenger hunt will give you the opportunity to show what you know and to discover what you “forgot” from Chemistry last year. You will be asked various questions and given websites to help you find the answers. If you already know the correct answer and are confident about its accuracy, answer it and get to the next question. All answers must be in complete sentences on a separate sheet of paper. All answers must be hand written.
