In science class we found out about the different boundaries there are, using a mars bar as an example. In this experiment we were able to see all the layers in the earth. I did enjoy this experiment because we got to see different layers of the earth in a fun and tasty way while being able to hear other classmates expressing their opinion on the topic. The first thing we did is break the mars bar apart to label those different parts of the earth. I think that the crust of the earth is the begining chocolate at the top. The mantle is the caramel part of the mars bar, then there is the core, made of nouget. I think a mars bar is not a good representation of the earth because with a mars bar, the caramel liquid is at the top where as in the earth, the liquid is at the core, in the middle of the earth.

                                     
Secondly, we observed what happened when the mars bar was pulled apart. When a mars bar is pulled apart, it is a divergent boundary, the direction of the two plate boundaries were opposite. If I was able to see a divergent plate boundary I would think that the tectonic plates would keep moving apart and make space for oceans and rivers.




                                 
Third, we observed what happened when the mars bar was pushed together. When a mars bar is pushed together, it is a converging plate boundary. It is a continent to continent plate boundary. A different converging plate boundary is an ocean to continent plate boundary, where the ocean and land meet. These are where most earthquakes happen. If I was able to see this on earth, I think mountains would form as the plates were pushed together.
                           

 

This is a crack in the Earth, this would result in fault lines appearing, this is how Earthquakes happen.

This is a transform boundary. A transform boundary is when one plate moves up and the other plate moves down.



Overall, this has been a very fun experiment and a very tasty challenge. Although this experiment covered most of it, some questions I still have are What makes tectonic plates move? How do scientists know how hot the core is? How / why did Pangea break apart? I hope I get to learn this in future classes.
