Workday (Wednesday and Thursday)

Kids need to build a sample of their roller coaster.  It must have two hills, or a hill, and a loop.

Measurements to be taken

1.Height of first hill:  (m)

2. Height of second hill (m)

3a and b.. Beespi measurement (m/s) of velocity at bottom of first hill   __ and bottom of second hill ___.

4. Mass of rolling object (g)

5. Length of track measured (m)

Kids must also take a video of their coaster from the side view (use the capture video option on Logger Pro or cell phone) as the object goes down.   Analyze this Video using logger pro as it
a) goes down the first hill
b) goes up the second hill

Determine the velocity at the bottom of the first hill using Logger Pro, and compare to the BeeSpi
Determine the velocity at the top of the second hill using Logger Pro
Determine the velocity at the bottom of the second hill using Logger PRo and compare to the BeeSpi

Kids must take a second video of their coaster explaining WHY their group built it the way it did.  This should be 30-60 seconds long and have all group members talking.
