Earth Pizza

We use the side view of a pizza slice to model the earth. We are only seeing a very thin part of the crust of the earth.

The crust of the pizza is the bottom layer, which in this case is the asthenosphere. The sauce in under the cheese is the lithosphere. The cheese is more dense then the meat or vegetables, which makes it the oceanic crust.This is everywhere on the earth, and the meat or vegetables is the continental crust, only being on parts of the pizza or earth.

Plate Tectonics

 To demonstrate the plate tectonics we used frosting and graham crackers. The graham crackers represent the lithosphere
1. Transform Fault- Plates slide past one another with no creation or destruction of lithosphere. I put the two graham crackers right next to one another and slid them past one another, like shown below.

2. Divergent Boundary- Two plates diverge, or move apart and new crust or lithosphere is formed. I put the graham crackers in the frosting and then pulled them apart. This is shown below.

3. Convergent Boundary- Plates converge, or come together. If a plate of oceanic lithosphere collides with thicker and less dense continental lithosphere, the denser oceanic plate will dive beneath the continent in a subduction zone. You can not use the graham crackers for this demonstration because they are stiff. A great example of convergent boundaries is when you run and jump on a carpet and the carpet hist the wall and bunches up.

Project W.E.T.

Project W.E.T. is an initiative program that has water based lessons for teachers to use on their students. W.E.T. stands for Water Education for Teachers. This is a great way to get students learning in different ways through activities and hands on learning.

The website of Project W.E.T. is http://www.projectwet.org/


Professor Klett then asked us to divide up $100 into the different forms of water:
Oceans- $96
Lakes/Rivers/Streams-$0.75
Glaciers/Ice caps- $2
Groundwater- $1
Atmosphere-$0.25

I was pretty close with oceans, glaciers/ice caps. and groundwater, but I was way off with lakes. Lakes consists of $0.007.
