More on Longitude

The discovery of how to figure out longitude while out in the ocean changed the world. Suddenly countries could have a powerful navy that didnt get lost in the ocean and trade became much more reliable. Here is the first of a film about how the problem of navigating the ocean was solved. It's the first of six parts.

Longitude also tells us about time zones. Let's figure out the time zones for Tracy and Mariola in Washington DC; you in Boulder; Ben in the Yucatan; Gill in Austrialia; Your dad and JoeJoeLilyand Little Ray Ray in LA; and Godzilla in Japan.

Everything starts in Greenwich England (the prime meridian) -- that's just becuase the brits were the ones to document all this. Here is a website that shows all the time zones. Australia has three so we need to look up Kingscliff where Gill lives.

Here is a really good video about the history of telling time

Latitude and Longitude Games

Hi Joe -- When you mentioned latitude and longitude I realized I couldn't remember anything about it. So I looked it up on the internet. Here are some cool sites I found.

Songs
I love this song -- it makes it easier for me to remember longitude and latitude
And here is another song. it's helpful but not as good a song.

Video Review
Here is a video of how to use google maps to find longitude and latitude of a place. 
Here is a great review of latitude and longitude. 
And a short movie. You have to answer a question and then it starts.


I like this one. It is a a  teacher from australia using google earth to teach about latitude and longitude

This reviews the topic and shows a lot of the math behind it

Games
And here are some games to practice:

Other Websites about using maps
You were so good at using the map in washington dc. everytime i would get turned around you could find us on the map. Here are a lot of websites about learning to use maps

Let's Do Together
Let's see if we can figure out the longitude and latitude of places we have been to. Here is a video of how to use google maps to find longitude and latitude of a place. 

  • Crystal Lake?
  • Washington DC
  • Isla Holbox (where the whale sharks are)
  • Boulder
  • Santa Fe
Maybe we can draw a map with the longtitude and latitude with all these wonderful places? We can draw a picture for each place to -- an icon. 

I'm going to try to find something that explains who invited latitude and longitude and why it is important.
