DIY Sundial
Let’s make a sundial and the shadow will tell us what the time is during the sunny part of the day.
You need a paper plate, pencil, and a little plasticine.
Write the numbers 1 to 12 at equal distances on the back of the plate. Make a hole in the middle and insert a pencil. Fix it with a plasticine. Place the sundial on a sunny place. Rotate the sundial to synchronize it with the current time.
This is a page with instructions to make a sundial depending of your localization and orientation. There is a video tutorial and it’s translated to several languages. I hope it were useful for you
