Summary- Using the information on the earth's layers from last week I made my "earth's layers foldable". The foldable showed Earth's layers as you get deeper and deeper into earth's interior; crust, mantle, outer core and inner core. Each layer had information on the composition, State of matter, and thickness of the layer:
(Crust- 5-100 km thick, made up mostly of silicon and oxygen in the form of granite and basaltic rocks, and it is a solid.
Mantle- 2900 km thick, made up of hot semisolid silicate rocks rich in iron nickel and magnesium, and it is a semisolid
Outer Core- 2200 km thick, made up of liquified iron and nickel, and it is a liquid
Inner Core- (diameter) 2456 km, made up of iron and nickel, and it is a solid)
Making a model to represent earth's layers made the concept easier to understand. As we finished our models, the new topic was the continental drift. Alfred Wagner believed that at some point in history all the continents were one or were connected based off the fact that some continents had the same fossils even though they were divided by seas. The "puzzle" of the continents that we put together showed fossils and curves that matched up after a few tries; it showed Alfred Wagner's theory.
SP2: Developing and using models-
I used models to explain and predict behaviors of systems, or test a design as I showed the layers of the earth. The clay model showing the layers of the earth helped me get a better visualization of how earth's layers look. Making the model showed me earth's layers in a different perspective; it helped me a lot.
