Ocean Navigation

We learned that compasses are used to improve the oceans navigation that people are trying to find there point. The compasses were invented in the Middle Ages.  We learned how to use the map to find the exact point that we had to find but then we used the compass to find the rest. Back in the day they used the North star to find their way around before the compass was invented. The compass wouldn't of worked really well if they didn't have two points to go to. The compass would actually find the way of how they would help the map to find the exact way to go. They used the map and the satellite to find the way when the compasses aren't invented. They use the chronometer to find the exact time of the longitude of the ship while sailing away. The first one was invented in 1761 by John Harrison but it wasn't until the year after that they actually made it work to use the latitude and longitude. They compasses, maps and the chronometer are very helpful in this time to know where we are going. The modern technology is used fill but I still know people that are using the compass to find their way.  It would of helped if we used a map to find the cards because they hid them in spots that we couldn't find or we didn't know where they were. This technology is modern but people still like to use the technology from the past to find their way. They do it because they think not all modern technology is good because it may not always work. They also want to teach their kids what they used in the past so they can tell their friends or their kids what they learned from their parents. No matter what, technology changing is helpful but still using the compass and chronometer is helpful.
