49.3 degrees was the average of 6
measurements. We also used a clinometer to find sun angle. The
average using this method was 48.3. We also found that the fist
technique (1 fist = 10 degrees) also roughly gave 50 degrees.
The temperature was taken at waist level. Six measurements were
averaged. The pictures show: 1and 2) angle measurement with
meter stick and protractor and 3) clinometer. |

The method using the meter stick and
the clinometer both gave a 30 degree angle. We confirmed this
roughly by using the fist method ( 1 fist = 10 degrees). |

Each value was the average of 12

filter. It appeared as a bright orange circle |

I am early this time! We rushed in and out
because it was so cold. We averaged 5 measurements for the
sun angle. We have a sundial on our courtyard that is
built into the paving stones. The student that acted as a gnomen
cast his shadow just after 12 noon. Pretty accurate, since solar
noon was 12:09.
