Today we had our much anticipated guest speaker, Mean Dean the Barbarian (also known as Grandpa.)
It was great! Grandpa taught them how to do a sheet bend knot (to tie the sail to a rope) and how to do a double half hitch knot (to tie the rope to the ship.) I'll have to quiz them later to see if they remember how to do the knots on their own. Probably not, but it will be interesting to watch them try.
He also went over compasses, bearings, and using a compass and map together. He even had them make a compass using a needle, magnet, and bowl of water. It was awesome!
