Build an Anemometer

All the materials you need to build an anemometer are on the tables. Choose a

table and start building using the directions on page 3 of the packet. Once you are done test your anemometer using the fan. Record the number of rotations in 10 seconds on all 3

fan settings. We will reconvene at 1:00PM.
