12th Grade Roller Coaster Review

Today during computer class, Mr. Picketts allowed us to see how the 12th Grade Roller Coasters work. The first one was the Candy Mountain. The Roller Coaster was build from wood sticks and candy. It was very original and awesome. My favorite part was when the marble finish the course in the candy house. I think that a 60 must be their grade. The second was a roller coaster with a japanese theme. The thing I like most was the many loops and that the structure was very resistant. I would grade them with an 58. They could decorate the orange tube. The third one was like a Mushroom Island Roller Coaster. In my opinion they deserve a 50 because the marble didn't complete the course and it was too simple. They could make better supports and add more things. The fourth one was The Soccer Roller Coaster. My favorite part was when th "marble" finished the course at the soccer goal. I would grade them with an 53 because they didn't use a normal marble, they use a really tiny marble so it make the course easier for that team, I don't think that was fair for their classmates. They could change the marble and add some supports in special parts. The fifth one was The New York City Roller Coaster. In my opinion they deserve a 57, because the buildings were awesome, there were like the real city. My favorite part were the buildings. I think they could improve in changing the track with a stronger one and use another thing to paste it than tape because it didn't look good all that tape around the track. Finally, the last one was Alice In Wonderland Roller Coaster. The thing I like most was the double loop and that there can go three marbles at the same time. I would give them a 55 becuase it didn't show many parts of the roller coaster. I think they could open the closed parts so everyone can watch the course of the marble.

Robot Demostration

On Friday, during computer class, a man named Abraham gave us a demonstration about robots. He explained a robot has many sensors. Sensors for light, ultrasound, sight, sound, and for many other things. Abraham told us that a new generation Lego robot would cost $400 dollars (very expensive). He also showed us how to make a robot move by a computer program. To make a robot move, you should put in the computer each move you want your robot to move. With this demostration I learned that a robot is very complicated to make it functional.
