What time is it? Time to try this fun in the sun activity. Once you build your own sundial, you may never use a watch again!
What You'll Need:
- Medium-sized stick
- Several small wooden stakes
Sundials have been used for centuries to help tell the time. Now, you can learn the secret. Start your sundial bright and early on a day that will be quite sunny. First, place the stick in the ground in an area that gets a lot of sun.
Then, place a small stake at the tip of the shadow cast by the stick and write the time on the side. As the sun moves through the sky, the stick's shadow will move. Keep an eye on your watch.
When an hour has passed, place another wooden stake at the tip of the new shadow cast by the stick. Write the time on the side of this stake. Continue to mark the shadows throughout the afternoon and be sure to write the correct time on each stake.
When you finish, you'll have a sundial! To find out what time it is, follow the shadow cast by the stick. It'll point to a stake, and you can see the time on the side of the stake!
