Transcript of spring scales
of food to determine the cost of their goods.
The seller would weigh the food to set a price.
A seller would also sometimes weigh the
object,minerals etc to see how much they
where worth. This made it much more hard
to be unfair with there trades. letters & packages The post office can weigh any
package or letter to be sure it is
safe to ship or travel. (www.Wikipedia.com) 1) economics- Weighing mail became easier
because they could take the scale
with them in the mail room and
saved them time and money. 2) culture factors- It increased correspondence and
helped people share more info. Affordable The scales where easy to make
and cheap to buy. If you where a
farmer or a seller, you could
probably afford a spring scale. Minerals
(gold, silver, etc... In some places, people traded minerals. The trader
would need to weigh the minerals to see the value. The spring scale is not too big which
makes traveling with it easier. If you
where a world wide seller, you could carry
a spring scale wherever you go. socially: Because everyone can afford it,
they are getting out farther and using
with more people than before. culturally: It increased trade and affected there traditions
by bringing people more available goods. How has the spring scale changed over
time? The spring scale is part of a very large group of scales each of which are more modern than the last. One of the first scale was probably a balance scale. Over the years scales got more complex. Now we have scales that are electronic. You can buy an electric scale for weighing yourself for example. http://www.google.com/imgres?q=electronic+scale&num=10&hl=en&biw=1366&bih=673&tbm=isch&tbnid=tr0g_kE6fSyrVM:&imgrefurl=https://sites.google.com/a/maricopa.edu/diamante/home/chemistry-1/lab-report-2-cheetos&docid=oeVyq0l7mq0BmM&imgurl=http://upload.ecvv.com/upload/Product/20093/China_Electronic_scale_ES_H_series20093241731398.jpg&w=361&h=373&ei=tOphUKirKoHJtAb68ICIDQ&zoom=1&iact=hc&vpx=637&vpy=316&dur=1752&hovh=228&hovw=221&tx=126&ty=141&sig=117572769872959176758&page=1&tbnh=146&tbnw=153&start=0&ndsp=21&ved=1t:429,r:10,s:0,i:118 http://www.google.com/imgres?q=balance+scale&num=10&hl=en&biw=1366&bih=673&tbm=isch&tbnid=o5LTxKA-A_LSmM:&imgrefurl=http://smecheerleader1994.wordpress.com/2010/02/01/balance/&docid=Q0nFC9JvDIhZpM&imgurl=http://smecheerleader1994.files.wordpress.com/2010/02/balance_scale.jpg&w=380&h=375&ei=S-thUJyFKMbJtAbFnICAAw&zoom=1&iact=hc&vpx=891&vpy=170&dur=471&hovh=223&hovw=226&tx=168&ty=135&sig=117572769872959176758&page=1&tbnh=137&tbnw=145&start=0&ndsp=18&ved=1t:429,r:4,s:0,i:151 http://www.google.com/imgres?q=spring+scale&num=10&hl=en&biw=1366&bih=673&tbm=isch&tbnid=wDQVbIM0uJvv9M:&imgrefurl=http://www.xump.com/science/Tubular-Spring-Scale-Brown1000g.cfm&docid=sQqERdjijaZhCM&imgurl=http://www.xump.com/Images/Products/Tubular-Spring-Scale-Brown1000g-500A.jpg&w=500&h=500&ei=1uxhUKmlCsTWsgaZhIGIBA&zoom=1&iact=hc&vpx=474&vpy=166&dur=89&hovh=225&hovw=225&tx=117&ty=122&sig=117572769872959176758&page=1&tbnh=130&tbnw=130&start=0&ndsp=22&ved=1t:429,r:2,s:0,i:145 http://www.google.com/imgres?q=weighing+minerals&hl=en&sa=X&biw=1366&bih=673&tbm=isch&tbnid=rDv3NHaA0Ob8aM:&imgrefurl=http://www.chemistryland.com/CHM130FieldLab/Lab3/Lab3.html&docid=gBSreEkuT7Es8M&imgurl=http://www.chemistryland.com/CHM130FieldLab/Lab3/MassOfGoldMineral.jpg&w=512&h=317&ei=M-9hUJ_-JcrEswbz_4CQCw&zoom=1&iact=hc&vpx=378&vpy=399&dur=124&hovh=177&hovw=285&tx=123&ty=152&sig=117572769872959176758&page=1&tbnh=123&tbnw=199&start=0&ndsp=18&ved=1t:429,r:13,s:0,i:111 thank you for
