1. Tyler and Christina are playing a game in which each player either wins, loses, or draws (ties) at each turn. The winner of a turn is awarded 5 points, and the loser loses 5 points. If it is a draw, 0 points are awarded. For the first eight rounds Tyler had the following results: lose, win, lose, win, win, lose, win, draw. What was Christina's point total for the rounds?

2. During an electronics experiment in your laboratory, you measure the voltage at terminal A on your newly designed circuit. You measure -12 volts. You check the same terminal after making a small change to the circuit and this time you measure -18 volts. What was the voltage difference between the two readings?

4. Mr. Waffle is a circus clown. He starts the day with sixty-eight pieces of candy. At the end of the day he has given away 383 pieces of candy. How many more pieces of candy did he have to get, in addition to his original sixty-eight, to be able to give away that many pieces?

5. Tasha finished the first draft of her history essay. The teacher said it had to be at least six hundred words long. She counted the words in her draft and found she had 369. How many more words does she need to meet the minimum word count for the assignment?

6. Courtney is very interested in cryogenics (the science of very low temperatures). With the help of her science teacher she is doing an experiment on the affect of low temperatures on bacteria. She cools one sample of bacteria to a temperature of -58°C and another to -85°C. What was the temperature difference in the two experiments?

1. In golf, the average score a good player should be able to achieve is called "par." Par for a whole course is calculated by adding up the par scores for each hole. Scores in golf are often expressed at some number either greater than or less than par. Ms. Floop is having a pretty good day at the Megalopolis City Golf Club. Her score so far after 15 holes is -5. If par for 15 holes is 62, what is her score?

3. It was a close race for the pennant (division championship) in the baseball league this year. The Rattlers won. Each team is awarded a point for every game won, and the team with the most points is the winner of the pennant. The Rattlers won 56 games. The Tigers were -2 (two games behind), the lizards were -7, and the rollers were -14. What was the average number of games won by the teams that did not win the pennant?

4. Four friends, who happen to be good golfers, played a round of golf (18 holes). Par for the course is 74. The players had the following scores (relative to par): -3, -1, +3, and +1. What was the winning score? Remember that the lowest score wins.

5. There was a 100-mile race at the Megalopolis Race Track. The winning driver had a time of 57 minutes. The next four drivers in order of finish had times (relative to the winning time) of +2, +3.2, +3.8, and +4.5 minutes. The sixth place driver had a time that was 3 minutes slower than the driver ahead of him. What was the sixth place driver's time? Express your

1. Certain mites in the arctic thrive at an average temperature of -51 C. They also do well at temperatures of up to 27 C. What is the temperature range acceptable to these arctic mites?

2. The water potential in one plant cell was calculated to be -4 bar. The water potential in another cell was found to be -11 bar. What was the difference in water potentials? Note: the bar is a pressure unit equal to about 14.5 PSI.

3. Mr. Bloop put a vial of protein powder in the -25 C freezer. It was accidentally left out on the lab bench by one of his students. It had been there for most of the day, and the temperature in the lab was 19 C. Once in the freezer, the temperature of the powder began to drop at a rate of 4 C every 5 minutes. Assuming the temperature change rate was constant (which it really isn't, but we'll pretend), how long would it take to get to the temperature of the freezer?

5. Acetylene is a flammable gas used in welding. The boiling point of acetylene is -84 C. If a sample of acetylene was cooled to 60 C below its boiling point (where it would become a solid), what would its temperature be?

6. Chemical Q is unstable at room temperature, so it is kept in a refrigerator at -37 C. Once removed from the fridge, its temperature rises at a rate of 4 C per minute. Assuming a bottle of chemical Q was exactly -37 C when removed from the fridge, what will its temperature be six minutes after removal from the fridge?
