My topic is about exploring the science behind the Roller Coasters. I had a toy kit with plasic parts which I used to build a roller coaster. It took me all night and the morning to finish it. But when it was done, it was cool and fun to play with. My friends loved it. This work I did building the plastic roller coaster, made me wonder how the real ones worked. I was also at Cedarpoint in June. I kept thinking how much fun science and technology provide to us. Part of my reason for me to think that way was your contest topic about how science is cool.
