## Th 5/21 - HW for F 5/22

#### Thursday, May 21, 2015

Thought question:
How might you use what we have done with shadows to calculate the height of something that is too large to use this method, e.g., a mountain or a building? Or to calculate the circumference of the Earth?

## W 5/20 - HW for Th 5/21

#### Wednesday, May 20, 2015

Using the measurements we took in class (h - height of light (from surface), d - distance of light from object (horizontal), l - length of shadow) calculate the angle between the surface and the light. Do this for each set of measurements.

## T 5/19 - HW for W 5/20

#### Tuesday, May 19, 2015

Experiment with shadows
5 different angles of elevation and corresponding shadow lengths
-angle of elevation is angle created between the light and the horizontal surface with the vertex at the intersection of the object and the horizontal surface.

## F 5/15 - HW for M 5/18

#### Friday, May 15, 2015
