Village of Barboursville Elementary 5th TAG
An angle has a vertex that is the common end point of two rays.
To measure angle with a protractor place the center at the angle vertex,
one side along the bottom, and read the angle at the other ray.
The Chair project in the Simple Machine set can be set at 7 angles.
Build the project.
Measure the first 6 angles and record the data.
Now graph the data.
Use that information to estimate the reading for the seventh position.
Measure and see how close you came.
We are also trying to figure out a way to use the angle sensor and RCX.
