5. Now for the fun!

6. What is your fastest driving speed ever, in a wheeled vehicle?

7. Units are important!
Dimensional Analysis is a method that can help with conversions and problem–solving in all science disciplines

8. Let’s play a game to see how conversion factors and unit canceling work

9. Deck of Cards Start Cards – a start card begins a conversion chain
Conversion factor cards – these cards are used for unit canceling
Solve cards – a solve card ends a conversion chain

10. Object of the Game
Be the player with the most points after 6 conversion chains have been solved

11. Starting the Game SHUFFLE! Deal 4 cards to each player.
The player with a START card goes first, and places the card on the table.
The next player must play a card that has a denominator that matches the START card unit. If the player has no such card, player draws a card from deck and plays it or keeps it and passes.

12. Playing the Game Draw a card at the end of each turn.
You can play a START card at anytime, but no more than 6 per game.
If you have no card to play, you must draw a card and play it if you can or pass.
A SOLVE card can be played anytime on a chain after at least 3 conversion factor cards have been played on the chain.

13. Scoring Points Anytime a START card is played, you score 5 points.
Anytime a SOLVE card is played, the player scores 5 points for each conversion factor card there is in the chain.
When a SOLVE card is played, everyone records the conversion chain on their game record sheet. Solve the chain. Compare answers. Correct answers score 25 points.

14. Ending the Game
The game ends after the 6th conversion chain has been solved.
Total up points
Subtract 5 points per card you still have in hand.
Highest score wins!
