SEMESTER TEST HELPFUL HINTS Hopefully you have been studying a little each day. Find blocks of time throughout the day and evening that you can study different units. Don’t spend a lot of time studying the units that remember well, study the units that you do not know the best. There are 82 multiple choice questions and 5 matching equipment on the test. Get a good night’s rest each night this week. Eat a good breakfast, lunch and supper. Your brain runs on glucose so don’t let your blood sugar fall. Don’t be on a sugar rush, though! Fill out the semester test review. A copy of the answer key is provided on the bulletin board in the classroom. There is also a copy on the Chemistry web page. Filling this out and checking the answer will help you prepare for the test. Take your old tests and quizzes out of your semester folder that was given back to you last week. Studying these will help you prepare for the test. Revisit the review games that were made for each unit that are uploaded to the wiki. Make sure to make an 8 x 11 crib sheet for yourself. Stay within the guidelines so that you will be able to use it on the test. You will hand this in with your test.

One partner will be “O” and the other partner will be “X”. You will choose a question to answer and then place your “X” or “O” in the square. You must get three in a row to win. Check the final answer key when finished with the game to check your answers. Game Board Question and Answer Directions. One person will read a question to their partner. If your partner tells you the correct answer, then they will roll the dice. If your partner does answer the question correct, then they will not roll the dice. It is now your turn to go. Vocabulary matching. Match the vocabulary word with the correct definition. When you have finished, turn the question cards over and make sure that the numbers match. Please shuffle the cards before moving on to the next station. Crib sheet station. You will be allowed to use an 8 x 11 white (or colored) sheet of paper for your semester test with ANYTHING WRITTEN on it that you want. The crib sheet must be written on with your won penmanship. There must be no photocopied pictures or crib sheets that are photocopied. There is a copy of the periodic tables that you will receive on this table as well. So, the information provided on the green and yellow sheets you will not need to write down on your own crib sheet. Laptops. Please use the laptops provided to access the wiki. There you will find all of the review games that have been made for you to review each unit. If the laptops are not available I will have printouts of the games and you can answer the questions and then consult the key for the answers to check. Periodic Table Review. Use the periodic table crib sheets to answer the questions at the station. Check your answer with the key provided on the bulletin board. Math Practice. Here are several examples of the math problems that may be asked on the test. Solve the problems and then consult bulletin board. Chem Semester Test Review. Use the semester test review packet that was given to you to review. If you are not done filling it out. Use this station to fill out your packet. If you are done you can use this packet to ask your partner questions. Previous Test/quizzes review. Use your previous tests and quizzes to study at this station. You can either look at your own to review or you and your partner can ask each other questions. Crossword: Fill out the crossword. The answers will be on the bulletin board for you to look at.
