Since the test was just given, the answers have not been revealed. Still,
I suspect the credited answer is B. Sigh. Why couldn't they have put "gram
: mass"?
Even worse is the question off our state's (Louisiana) science exam for
8th graders.
-- start --
1. Elysa must find the weight of a rubber band for a science project.
Which unit of measure should she use?
A. kilogram
B. hectogram
C. gram
D. milligram
-- end --
The credited answer is D -- milligram. I still don't know why.
Disregarding the whole mass/weight issue, any of those would work. MKS
says you use kilogram. That's what our school teaches. Milligrams would
work, but since most rubber bands are in the 5 to 10 gram range, grams
seems easier.
