Summary

The rock cycle the cycle of how rocks turn into different kinds of rocks. There are three kinds of rocks: sedimentary, metamorphic, and igneous. One thing that is different about the rock cycle is that it's not really a cycle (like the water cycle for example that repeats in a circle in a certain order), it is more like a rock web. A sedimentary rock has several layers. Over time, different sediments layer over each other and become 1 type of rock. An igneous rock is actually just cooled and solidified magma or lava. A rock turns into a metamorphic rock with pressure. Now, back to the web concept. The reason why the rock cycle is like a web is because there is no specified order. Any kind of rock and turn into any kind of rock by any many ways. That's why it's more like a web than a cycle.

SP2: Developing and Using Models 

 This week we developed models of the rock cycle and a volcano (which we will use later when they are finished).We created a rock cycle cartoon. First, we rolled different dices and recorded some data. Then we used that data to create and develop rock cycle cartoons. We also developed and created paper mache volcano models. First, we used a paper template which we cut, then we wrapped it around a (PVC? I think?) pipe. We next covered the whole model with wet sticky newspaper coated in glue.
