RE: Re: Hiking Related Science Project?

I've been playing with this stuff for a while and have a pretty good set
of standards if any of you want some ideas of how to test cheaply and
efficiently.

Idea: 

Test efficiency of a canister, esbit, alcohol, and fuel stove.

Comparison, weight of fuel required to bring 1 pint of water to TRUE
boil in a standard pot.

Requirements - one pot, a candy thermometer, a watch that shows seconds,
and a measuring device that shows amounts down to the 1/4 ounce or the
ml. I prefer a 10 ml syringe.

Conclusions: What I have been doing is weight efficiency comparisons.
Example - a gas stove requires only about .2 ounces of fuel to achieve
boil, and an alcohol stove requires about .4 ounces (weight). But
comparing base weight, the alcohol stove is more efficient for pack
weight.

Of course there is a ton of data, but you get the idea. My boys love
helping when I test stoves. For my site.

What a timely post.  My son (ninth grade) was just discussing this 
yesterday !!!!

I suggested that he experiment with how fast 2 cups of water came to 
a boil with different color pot bottoms.  Like trying black, yellow, 
blue, aluminum (silver).  It would be a bit messy because you'd 
either have to have four identical pots and paint them all, or strip 
off the paint from a single one.  You'd need to make sure that the 
starting water temperature was identical.

This would be a fairly straight forward one........many of the ones 
kids do end up being a lot of work.  Measuring calories burnt or 
breathability are difficult things.
