Competitive STEM - Science Olympiad Kit directions 

It's hard to know without more information. Maybe your board is not exactly the right size? It might not matter if it's not quite square as long as it works.

Awesome! Congratulations to your son.

If I don't place either of the blocks in the half-pipes, it takes right around 60 seconds.

@@AndrewGatt Thanks! Also where can I find the papers for the last part of the coaster. When the marble Rolls constantly back and forth.

@@cassidy6516 I sell the kits and templates at paperrollercoasters.com.

I do not understand what you mean by "record and note the logs"

Thank you for your reply, For the Data logs ( can you please share how to record the gap score and the loop score)

@@user-xs4mg5fp9w The gap score is the length of the gap, rounded down to the nearest centimeter multiplied by 4. The loop score is the height of the loop, measured from the point of intersection to the highest point on the inside of the loop, rounded down to the nearest whole centimeter, multiplied by 6.

@@AndrewGattsomeone in my comparison did not label the highest point, so they did not get loop score

@@RYbreadd0 Those rules are very tricky. I'm sure a lot of students missed the labeling requirements for the loop and the gap.
