This is the reflection that I did for my mask, I think that I did well making my mask and I did well for making my reflection:
My learning goals of 2012 are to be more organized, get better grammar and to be able to write better.
I think that I have achieved all of these goals because I have worked hard to do all of these and I am proud of myself.
This is my Man Vs Grade 6 video that we showed during the assembly.

A roller coaster works by getting pulled up a little hill in the beginning by a train. Then it goes down by pure momentum, without gravity, roller coasters would not work. It is all based on gravity, a lot of math is also used. In the past, they were made by wood and were not as strong and were not as safe. They would have to be repaired a lot.
Now, we have roller coasters that metal now. They are much better now.
