Stacy and anyone else who wants to comment on session #5

When I talked to students about how mountains form the most common
thought for my 6th graders was that the mountains are formed volcanic
eruptions. They also believed that mountains formed when the land split
like in an Earth quake and the jagged rocks left behind smashed together
and made the mountain. They think that the higher the mountain, the
older it must be because it is the tallest. Some other ideas about the
formation of mountains was from God, erosion, and from when two plates
come together and they smash together and the land rises up. Some of my
students think that the width of a mountain will tell the age. They
also believe that if you can climb it, then it must be younger than
other mountains that you cannot climb. I was surprised at some of the
answers, but some of them while they seem silly really were what they

Some ways that I think will change students thoughts and belief on how
mountains form would be to give them demonstrations on how plated come
together and the reaction that takes place at the boundaries as the
plates move. Students need to be educated on how earth quakes, plate
movement, and volcanic eruptions help to shape our land and can help to
create different land forms that exist on the Earth. I tried the play
dough idea with my students when I talked about the formation of
volcanoes and they seemed to understand better how the land would rise
up as a result of the plates moving together. The idea that the plates
would slide together was a hard concept for the students, so showing
them maps of the world and how the maps and continents are believed to
have moved, gave them a better understanding that the world does have
plates and that these tectonic plates move. I also took the time to
point out the plate boundaries and the common factor that exist at those
boundaries, that being mountain ranges. The students took the pictures
and experience and made the ideas their own. Real life experience and
exposure gives the students ownership for the material.

Any thoughts....
