*Spokane words for camas, the land where it grows, basalt, root digger

-pux pux
*Type of biome where the camas grows in

-dry desert land
*Types of rock and soil found there and how the rocks were formed

-basailt... sand...
*Type of climate and precipitation. (Why is it so dry?)

-dry, hot...
*Types of elements and minerals commonly found in the rocks

-iron
*Pictures or diagram of the energy cycle in that biome (see biology text for help)
*How the plant is harvested explain why the root digger is needed (what gets in the way?)

-root is far in the ground... rocks might get in the way...
*A drawing of a root digger with labels explaining (type of machine, how it works, what is it's

mechanical advantage, how does it work on the soil, rocks and plants?

1. Every object in a state of motion tends to remain in that state of motion unless an external force is applied to it.

2. The relationship between an objects mass m, accelaration a, and the applied force f is f=ma. Accelaration and force are vectors (as indicated by thier symbols being displayed in a slant bold font) in this law the direction of the force vector is the same as the direction of the eccelaration vector.

3. For every action there is an equal and oppisite reaction.
