Activity A,Get the Gizmo ready,Dimensional, Check that the question is still about Burj Khalifa. Goal Use dimensional analysis to solve conversion problems. 1 Observe In the question you are asked to convert kilometers to centimeters To do this. first you will convert kilometers to meters Drag the 1000 meters 1 kilometer tile down. A What do you notice, B Because kilometers appear in the numerator of one term and in the denominator of. another they cancel or disappear The process of converting units by canceling is. called dimensional analysis,How many meters are in 0 828 kilometers. C A meter is a much shorter unit of measurement than a kilometer Based on this fact. does your answer to B make sense, 2 Identify Now find a tile that converts meters to centimeters Drag it down next to the first. A What units cancel now,B What is the unit in the answer.
C How many centimeters tall is the Burj Khalifa,D Click Submit Is this answer correct. 3 Find Click Next What conversion tile can you use to solve this problem. 4 Analyze Drag this tile to the green strip Turn on Show results. A What units are given to the right of the equals sign. B Why didn t the units cancel in this case, C What do you think you could do to make them cancel. Activity A continued on next page,Activity A continued from previous page. 5 Observe Click Flip tile,A What unit is given now. B Click Submit How many millimeters wide is a human egg cell. 6 Practice Turn off Show result Make sure Metric units only and Distance are selected. Click Next and use what you ve learned to solve another unit conversion problem For each. problem list the units given the units asked for and the solution. A On a caterpillar s map all distances are marked in millimeters The caterpillar s map. shows that the distance between two milkweed plants is 4 012 millimeters What is. this distance in kilometers,Given unit Answer unit Solution.
B The closest star to our Sun is Proxima Centauri which is 4 242 light years away. What is the distance to Proxima Centauri in kilometers. Given unit Answer unit Solution, C A helium atom has a diameter of approximately 9 8 10 11 meters What is the. diameter of a helium atom in nanometers,Given unit Answer unit Solution. 7 On your own A blue whale has a length of 28 578 millimeters What is the length of a blue. whale in kilometers Show your work below by writing the conversion factors you use to. solve this question,Get the Gizmo ready,Activity B. Check that Metric units only and Distance is still. Metric units, Introduction During the Warm up activity you learned that 1 000 meters equals 1 kilometer. Both of these units are part of the metric system a measurement system based on powers of. 10 No matter what quantity you are working with converting between metric units will involve. multiplying by a power of 10,Goal Convert from one metric unit to another.
