45.5 - 48 |
|
We measured the angle at 48
degrees twice, once using a basic protractor and again using an
astrolabe. When using the ImageJ we got about 45.5 from our
pictures...attached. We are also tracking the shadow length of a
few of our students. It will be interesting to note how it
changes through out the year. We'll be in touch again in a
month! Happy equinox! :o |
