Investigation 1B Conversion Chains 1 1B Conversion Chains How can you use unit canceling to solve conversion problems? Suppose you are traveling in Canada or Mexico, and you see a sign that says the next city is 115 km away. How many miles is that? You could use the dimensional analysis process to figure it out. Dimensional Analysis is a method of using conversion factors and unit canceling to solve unit conversion problems. In this activity, you will use conversion chains to start and solve conversions. Materials Conversion Chain Card deck Conversion chain table for recording chains and solutions Calculator 1. Conversion Chain Cards The deck of cards contains: 12 START cards, 12 SOLVE cards, 36 conversion factor cards 1. Look at the cards to identify what a START, SOLVE, and conversion factor card looks like. 2. Shuffle the cards thoroughly! 2. Creating conversion chains The object of the game is to have the most points after solving 6 conversion chains. 1. Deal 4 cards to each player (works best with 3 5 players). 2. Choose a player to go first. This player must play a START card or one card that will correctly continue a conversion chains. That means that the card must have a denominator unit that matches a START card unit, to cancel the starting unit and continue the chain. Anytime a START card is played, the player scores 5 points.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
