3. Purpose If you are unfamiliar with the game show, the purpose of this program is to answer questions correctly to form 3 X's or O's across, up and down, or diagonally. This particular game would best be played with a smaller group of students, that you can separate into two groups. One group would play X’s and the other group O’s. How to Play When you reach the opening screen with the names, you must click your mouse each time you want a new name or caricature to appear. Then, after all caricatures have appeared, click again for the main game screen. One of the two contestants picks their first square. Let's say Susie goes first and she is X. She chooses square 5. You must click on the person in the square in order to go to the question for slide 5. After clicking on the person, the question for that square appears.

4. There are 2 ways you can play this game: FIRST WAY….. Let's say the question is "What is the average speed of a car traveling 300m in 20sec?" Give the team a chance to answer the question and then click again. The answer of the contest appears. This answer may or may not be true. The team has to decide whether they agree or disagree. Click Again and the correct answer will appear. If the team was correct press the home arrow and it will take you back to the board where you can manually enter an X or O.

5. SECOND WAY…. Have one to two students in pretend to be in each square. One of the two contestants picks their first square. Let's say Susie goes first and she is X. She chooses square 5. You must click on the person in the square in order to go to the question for slide 5. After clicking on the person, the question for that square appears. Let's say the question is "What is the average speed of a car traveling 200m in 20sec?“ The person who you have assigned to the middle square then has to answer (or bluff) to that question. Let's say that Johnny is square 5 and says “15m/s". Susie then has to agree or disagree with Johnny's answer. After she has made her decision, you click the mouse twice and the correct answer appears. Click on the menu arrow to return to the main game board. If Susie agreed with Johnny, she was wrong. Therefore, you would put an "O" in the black box in square 5 by clicking in the black box and typing and uppercase "O". If Susie disagreed with Johnny, you would put an "X" in the black box in square 5.

6. For both ways….. Alternate contestants until someone has made 3 in a row. *****NOTE: Once you enter the "X" and "O" into the game board, you must go back and delete them from within the presentation before you begin another game.

9. 1 What is the density of a marble that has a mass of 10 grams and volume of 5 cm 3 ?

10. 1 I think it is 5 g/cm 3

11. 1 WRONG! It’s 2g/cm 3 Home

12. 2 Are grams used to measure mass?

13. 2 No! I weigh myself in pounds.

14. 2 Sort of, but we are not talking weight. We are talking mass and grams are used to measure mass. Home

15. 3 Calculate Momentum: Mass = 10 kg Velocity = 6 meters/second

16. 3 Math was never my strong subject….I think you divide 10 kg by 6 m/s….to get 1.6 kg/m/s.

17. 3 You’re right. This isn’t your strong subject. You don’t divide. You multiply 10 kg and 6m/s = 60 kg · m/s) Home

18. 4 How much force is needed to accelerate a 1,300 kg car at a rate of 1.5 m/s 2 ?

19. 4 Um….I think you would multiply 1,300 kg and 1.5 m/s 2 and that would be……..1950 N…maybe

20. 4 Good Job! 1950 N is right! Home

21. 5 A car traveled 150 km in 2.5 hours. What was its average speed in km per hour?

22. 5 Easy 150/2.5 = 60 km/hr!

23. 5 Home WOW! You’re Right!

24. 6 What is the density of 12.0 milliliters of a liquid at 20°C (293 K) that has a mass of 4.05 grams?

25. 6 Well, at 20°C you would divide 20 by 4.05 g which would be about 5….yes that’s right.

26. 6 Not quite…for density you divide the mass by the volume. Therefore, 4.05 g /12 ml = 0.338 g/ml Home

27. 7 A frog leaps from its resting position at the lake's bank onto a lily pad. If the frog has a mass of 0.5 kg and the acceleration of the leap is 3 m/s², what is the force the frog exerts on the lake’s bank when leaping?

28. 7 Oh…I know! Frogs are too cool! Their force would be 15 N.

29. 7 Home Not so much…to figure out the force, you have to multiply the mass (0.5 kg) by the acceleration (3 m/s²) which equals 1.5 N.

30. 8 A sample of an element has a volume of 78.0 mL and a density of 1.85 g/mL. What is the mass in grams of the sample?

31. 8 OH! That’s tricky….. 144 grams? Don’t I have to rearrange one of the equations? Home

32. 8 Yes, you do! You have to flip around the density equation and multiply the density and the volume and you did it correctly!

33. 9 A ball moving at 30 m/s has a momentum of 15 kg·m/s. The mass of the ball is….

34. 9 Momentum…well that is mass X acceleration so the answer is 450 kg.

35. 9 Well, you got the right equation, but you have to rearrange it a little. To figure out the mass you need to divide the momentum by the velocity….so the answer would be 0.5 kg. Home
