Students received their instructions for the sundial. The sundial is not due until April 26 so that we can find a few good sunny week-ends. This Friday is supposed to be good and that is why I assigned it so early.
Basically the instructions are: Put a short stick, pencil or other straight object in the bottom of a paper. Turn the paper so that the straight object makes a shadow on the paper. Mark North South East and West Set a timer and every hour go and mark the shadow - mark from the stick to the end of the shadow and write the time down. Five markings are required. Make sure the paper is in a safe place and anchored so it doesn't blow away or is not attacked by the family pet.
In class we corrected last night's homework. Then we did a review of simple machines on Edhead.
