K-Nex Rollercoaster

by Sam L. and Sydney

We are building a K-nex rollercoaster that is going to be very big.  It is made out small K-nex. K-nex are little multicolored pieces of plastic that you can stick together. We are making it by putting the pieces together.  It even has a motor to move the balls along the track.   Different people in our class are working together to build the rollercoaster.  Alex, Josie T., Charlie,  Sam L. and Sydney have worked on it the most during Choice Time and Open Door.

There are twenty steps that we are following to help us build. We are on steps four and five, and we are connecting steps and walls made out of K-nex. We have built the end of the rollercoaster. It takes about a couple of days to finish a step. Each step is very different. Not all steps are alike. Some steps are hard, some steps are easy and some steps are in the middle.

We are making a long pole. Sadly we don’t know yet what it used for.  We have to do a lot of work on the K-nex rollercoaster.  We have to work hard, cooperate with each other and pay attention to build it the right way.  It has been a lot of fun. WE CAN’T WAIT TO FINISH IT!!!!
