Today i learned about motion and forces like inertia and friction. Here is a website to make blueprints of a roller coasters.. and it helps you learn about forces, motion and physics.

I also learned about different kinds of forces, such as: applied force, gravitational force, tension force, frictional force, and normal force. It will be interesting to see what other things I will learn.

I did many things around Christmas time. We had friends come over for the holidays, a big Christmas dinner, eggnog, having christmas early (on Christmas Eve), shoveling the drive way[they can't all be fun], and passing Swim Kids 5. My favourite gift was the Lego Cole's Tread Assault [not me Cole]- which is next to my EB Games gift cards. Also when one of our friends came over they brought a puppy[as seen in picture]. Most of the time, we just relaxed, spent time with family and friends, went swimming and played games. Overall its been a good Christmas.
