Today I completed this weeks Nano girl task. For this task I had to try create sundial. A device that shows the time of day by the position of the shadow cast onto a marked plate by an object with a straight edge.
First I watched a video that Nano girl made to show how to make a sundial. I used cardboard and tape.Instead of using regular tape, I used duck tape because I didn't have any other tape I could use.
Then I made my shapes by drawing a circle and a right triangle on the cardboard. After that I used scissors to cut out the shapes. I used tape to stick my right triangle onto the circle. Afterwards I wrote 2 different times. One that the tells the time when I should wake up, and another which tells what time I should go to sleep.
Then I tested my sundial using my torch. It was quite interesting because I wondered how did people think of this thousands of years ago. I surprise some that was used thousands of years ago, stills work.
This task had to be one of the most fun task I've done yet.
Kia ora Siale

Yea sun dials are cool as!!! They date back to Ancient Egyptian times, 3500 years ago, maybe even older but we can’t tell because of a lack of evidence.
Makes sense though right. Before we had clocks or a way to tell the time, we would just look up and see in the sky where the sun was. If it was right up above us then we know it must be about the middle of the day. The sun dial then lets us be more accurate with our observation of the sun.
Did you leave your sundial outside and see what it shows you throughout the day? It’s not very accurate with a torch because you control the torch so that means you would control the time haha. Wouldn’t that be nice?
Mā te wā,
