Have your assistant grab a few items from the cupboards to use as test objects. For example, bags of sugar or flour work well. With your eyes closed, try to guess how much they weigh! With a little practice, your guesses will likely improve. After trying your luck at guessing weights, try using a scientific tool: a scale!
Test objects to make sure their stated weights are correct. For example, a five-pound bag of sugar would work well for this experiment.
Grab the bathroom scale and take some measurements to confirm the objects' weights. Do you find any discrepancies? If you want to make your own homemade set of balance scales to compare the weights of small objects, follow these simple directions to make scales out of cardboard and a ruler or a plastic hanger and cups! Did you get it? Test your knowledge.

Feb 8, Lucas Feb 6, I always wondered why it was lb and now I know. So how do we get lb for "pound" and oz for "ounce"? Lb is an abbreviation of the Latin word libra. The primary meaning of libra was balance or scales as in the astrological sign , but it also stood for the ancient Roman unit of measure libra pondo , meaning "a pound by weight.
The Italian lira also used that symbol with two lines through it , the word "lira" itself being a shortened version of libra. By Southern Living June 13, Save Pin More. Comments Add Comment.
