Sundial

In maths, we've been learning about sundial for the past few weeks. We've also decided to make one ourselves, so today this is the finishing product. As you can tell by the picture it says about 8:20 - 30 am but it was actually taken at 9:27 am. It looks like that because we had a daylight saving which added another hour in the time. 

3 Interesting Facts about a sundial
1) What's a Sundial? A Sundial is the oldest known device used in the ancient time when the clocks weren't invented. They also used candles, hourglass, and stars to tell the time. As the sun moves through the sky, the gnomon casts a shadow that aligns on the markings. When its midday, the gnomon casts a short shadow. The long shadows are cast when the sun is lower.

How I made my sundial?
What you need: a piece of wood, pencil, rubber, ruler, coping saw

Step 1: First you have to choose a shape for your base. You can neither choose a square, a circle, or a semicircle (I choose a semicircle to make it easier). 

Step 2: You cut it out.

Step 3: Make a gnomon (a part of a sundial that cast a shadow). 

Step 4: Glue the gnomon and the base together.

Step 5: Add the numbers and the line in the clock.

Step 6: Add your designs to make it fancier.

Then, you all done!
