==== Paddle Wheel ==== ==== Paddle Wheel ====
-{{props:kinexpaddlewheel.jpg?400|paddlewheel}}+A paddle wheel (in this case, made out of snap-together constructive toys) can be used to demonstrate the effect of a force vector field on a physical system.

==== Pumpkin Quarters ==== ==== Pumpkin Quarters ====
-{{props:pumpkinquarter.jpg?400|pumpkinquarter}}+A pumpkin that has been sectioned into quarters can be used as an interactive physical representation of a spherical coordinate system.

 +==== Surfaces ==== 
 + 
 +We use plastic surfaces of multivariable functions that are dry-erasable, transparent, and lightweight. The surfaces were created as part of the [[https://raisingcalculus.winona.edu/|Raising Calculus to the Surface]] and [[https://osuper.science.oregonstate.edu/content/raising-physics-surface|Raising Physics to the Surface]] projects. Surface Kits include a surface, its corresponding laminated contour map, and a slope measurement tool.

 +==== Contour Maps & Vector Maps ==== 
 + 
 +We print out contour maps or vector maps and put them in dry-erasable sleeves. Often, our maps correspond to plastic surfaces.
