Bathymetric Mapping

Field Trip

Yesterday during the Oceanography field trip, I learned a lot with my group. While we were on the boat, I learned how to use a compass to navigate a map and draw latitude and longitude lines. I learned how to catch plankton, and to view their activity through a microscope. I learned how to hold a crab, which was fun. I watched a lobster crush a water bottle with its strong claws. While we were at the beach, I learned more about erosion and the formation of how beaches came to be. I looked at sand through a magnifying glass and saw how it is made up of thousands of tiny rocks. I learned a lot more about sand dunes and how they are formed. Sand dunes have beach grass on top and their roots go all the way down through the dunes which help to keep the dunes standing. I had a really fun time on this field trip, while learning a great deal as well.

Pangea

In class this week we did an activity called "Dancing of the Continents". During this activity we cut out each continent with their mountain ranges and rock formations. Then we put each seperate continent back together, forming pangea. The "Dancing of the Continents" activity was really fun and also informative. I learned how the formation of Pangea was originally mapped and how it split apart. The theorys shown in the paper are exemplified in the maps that we drew. Each mountain valley and rock formation that was split apart from pangea, fits together perfectly when you form the continents back together. Scientists share their theories with each other and come to different conclusions of what they think the solutions are. They use their information to help each other come to a common conclusion.
