 * Measurement, Dimensional Analysis & Significant Figures**



The attachment above is mentioned in a High School discussion (on this Wiki) called "Thoughts on Dimensional Analaysis (DA)". In that discussion I propose that we take some district-wide steps (starting in the elementary grades) towards developing better mathematical habits among our students, particularly those that become critical to comprehending and solving upper-level scientific problems/equations.

E. Hall - "First day lab" asks students to weigh, then burn matches and record observations. Basic calculations involved and good for starting conversations about qualitative vs. quantitative observations.



The attachment above is a lesson on how to isolate variables when solving equations, particularly in the physical sciences. Some quizzes about this follow this post. (Byrnes at Hiatt)



The attachment above is a quiz over the lesson which is one post above this one. (Byrnes at Hiatt)



The attachment above is another version of the same quiz over the lesson which is two posts above this one. (Byrnes at Hiatt)



A simple metric converson worksheet with emphasis on metric prefixes. Reproduced from the files of Don Murphy. (Crow @ Lincoln)



A short worksheet reviewing scientific notation and basic conversion factors. (Glencoe sect. 2.2) (Crow @ Lincoln)



A 10-minute activity to reinforce the "guess once" concept in measuring. Students take 7 measurements on different types of scaled devices then asked to re-read each on they read incorrectly. Minimal setup. (Crow @ Lincoln)
