buliding roller coasters

I think building the roller coasters was so far the most creative and fun thing we have done all year in science class. the best part about it is that the omega money. you actually have to but the parts for your roller coaster. it also when you get rewarded omega money it feels good. it fells like your doing really good and the teacher is proud of you during that time period. every day i look forward to science class because we are always doing something fun and enjoyable.
