science fair project

My son has to do a science fair project. He wants to involve kayaking. Does anyone have any good ideas?

Have him compute how many uses he can fit in a hardshell. My Eco Safe is rated for 50

Hull design and stability.
Pin rescue forces.
Analysis of an eskimo roll. Centers of gravity, force vectors, etc.
Scale model and fluid dynamics.....

Some ideas:

1) Calculate stream flow at a given point (V x A = Q), evaluate three candidate sites for gaging suitability.

2) Describe river morphology and it's relation to eddies, hydraulics, standing waves, etc. Discuss with respect to whitewater park design.

3) Compare the mean timing of peak runoff from a 20-year period over 50 years ago with the timing of the last 20 years and evaluate whether a change exists and discuss implications relevant to climate change.

4) Compare the timing of a stream stage pulse from a dam release with the velocity of the water actually moving downstream.

Count could've come up with a much more extensive list...

Have fun!

How about a mock river with little rapids and eddies run by an electric pump system. Lots of ways to make it a science project....
- tracking sediment collections
- where does trash end up
- river width and depth comparisons that change water flow
- effects of flash floods
- how waterfalls are made
- how creature crafts can go down anything, but some think that's cheating
etc etc.

Keep it simple: Demonstrate how a Z-drag works as a pulling force multiplier.

How about: how long can you hold your breath under water at different hart rates. You could exercise to get the hart up and do a graph of sorts.

Use glitter or colored sand to demonstrate both sediment and show different water velocities in different parts of the river.

Put a Foamie in the system for general interest.
