Light Unit Review Sheet Part I:
Instructions: This year our light unit will be abbreviated. The test will be held on two consecutive days on May 21st & 22nd. So I will be assigning review sheet questions as we go along. Copy and paste the questions into a document so that you can add questions to the document as I assign them.
1st Set: Due Wednesday, April 23rd: Because we did not finish the lab on Friday, WE DID NOT GET to all the topics I originally posted below. So I reduced the assignment to these 5 questions, which are due by April 23rd.
