Skateboard Ramp for Pros!
Steep or gentle slope: which one is for you?
Driving Question

You have three kind of skateboarders: the first one has never been on a skateboard.  The second one has tried skateboarding for a few weeks and the last one has been skateboarding for the past 2 years.  The three of them want to try a few ramp jumps, but don’t know anything about slope and steepness.  You do.  They want you to help them decide on a ramp design the three of them can use without losing a limb.
