What about hot air balloons. These can be made from brightly colored tissue
paper. (surface area/volume). they can calculate the volume of air in the
balloon and the density. They can use temperature relationships to
determine the density of hot air. they can calculate the rate at which the
balloon should rise they can calculate wind speed. There are a lot of
posibilities.

Hey all,
I want to create a year-long math project for my sixth grade class.
Ideally, this would be something that the kids would build at the end of the
year requiring an extensive amount of mathematics to plan. Perhaps
something which is simple to build but can have many different variations.
My hope is that, in addition to teaching the mathematics necessary for the
project, the kids can test it using spreadsheets before construction.
So far, I've thought of,
A catapult/projectile where the kids make a launch pad and target,
CO2 car
Garden design (planting at different times to achieve correct look after x
number of days)
Solar oven
But none of these are quite right. Any other ideas out there?

How about a scale model of the solar system across your city? This
involves making a scale that's big enough so you can see the planets (even
if they're just dots) but small enough so that the model fits in a
geographical area that's accessible, contact stores in the proper
locations to host the planets and the planet and project info,
constructing the sun and planets, doing the measuring, etc.etc. It takes
a while. I did this with a high school physical science class and it took
us a month to get everything set up and done...
