Try
this! Set up your own shadow stick clock like these fourth
grade students in Minnesota did. Here's how:
- Use
an atlas or other resource to look up the latitude of your
town. Use a "protractor" to insert a post (stick
or yardstick) into the ground at the same angle as your
latitude.
- Use
a compass to make sure the shadow stick points North. That
aligns it with earth's axis. What next?
