Backyard CompassIn Signs & Seasons, our first field activity is to make a "backyard compass" that will help orient the observer to the compass points while making observations of the Sun, Moon, and stars. Here's a pic of my 13yo son Happy standing in the backyard compass he and his younger brothers made.
The boys made it their little busy project, which is always a lot of fun for their Mom to watch. They did a fine job. The compass is slightly off from true north and south, but it does the trick. We had a hard time finding enough round paver stones so we used bricks for the intercardinal points, NE, NW, SE and SW. Note that Happy's shadow is very short. This shot was taken on about June 17, very close to the summer solstice. If we come back on the equinox, his shadow will be about his height, and on the winter solstice his shadow will be twice as long as that. Also note that his shadow is slightly pointed to the west. This tells you that it's not quite "High Noon," which occurs at about 1:30PM in our longitude during daylight savings. Let us know how it goes if your kids make a backyard compass. Send us a pic and we'll post it. Leave a Comment Leave a Comment |
