Room 12 has been learning about landforms.  We learned about rivers and that they flow from high (mountains) to low places (ocean).  We also learned what happens to rock as it flows down a river to the beach.  The strong flow of the river makes rocks crush into each other, breaking them apart, causing the rock to break into very small pieces that eventually end up in the ocean because all rivers flow to the ocean.  We also learned about erosion and how canyons are formed.  We had lots of fun doing our experiments.
