In today's lesson we went over different maps throughout history and how they changed over time. The first map we saw didn't even look like a map and was made out of sea shells and bamboo, this map was supposed to represent were certain islands were and the high and low tides. We also learned that maps used to be mainly directional devices explaining how to get from point A to point B, but are now most commonly used to communicate the location of complex geographical places. The next thing we talked about were meridians and parallels, a meridian is an arc drawn between the north and south poles using latitude and a parallel is the same thing but it uses longitude. The last thing we learned was scales on maps and how they can be written in one of three ways a ratio or fraction, written scale, or a graphic scale.
