Use the link above to discover how to build and use your very own anemometer!

Answer the following in a video response.  Choose your app.
       What I mean is create an answer that demonstrates your answer.
1) Why do you think the cups should face the same direction?

2) If you have a fan that turns at different speeds, hold the anemometer in front of the fan and count the number of times one cup completely turns around for 15 seconds, then multiply that value by four. This number will be in revolutions per minute (rpm). Repeat this while keeping the fan at the same distance, but changing its speed. How did the rpm change when you held the anemometer in front of the fan at a slow speed compared with a faster speed?

3) Graph your data from testing your anemometer.
