The sundial experience

Do you know about sundials? Well we are going to educate you on some facts and some interesting information about sundials. First, you will need a paper template of the sundial and cardboard to keep it positioned. You will need to cut it out to put in the sun. There were 2 pieces that we had which were the surface (sundial) and the gnomon. The gnomon was used to cast a shadow from the sun. You will need to make sure it is sunny to conduct your experience. If you don't have a lot of sun you might not be able to see a shadow. Did you know ancient people used sundials before clocks and watches were invented? On Monday when we put our sundials out we noticed that the shadow from the gnomon had shifted positions. This is because the Earth is rotating around the sun and spinning at the same time. We now know how ancienct civilizations told the time and how important it is for today's technology of watches and how we function as a society.

How a compass works

Did you know a compass uses magnetism to show you which way is north and south? We used a needle, magnet, sponge, cork, and a tray of water to test it. We had to rub the magnet onto the needle so it could be magnetized because it will help us know where North is. When we put the needle into the water to float some of our needles sunk and some floated. When we magnetized the needle it pointed North towards O'Donnell Avenue. Some did not work and were not able to show us where North was because we couldn't get the needle through the cork. Sometimes the sponge got soaked and sunk. The reason why we conducted this experiment is because we are going to camp in a couple of weeks and we will need to know where to go if we get lost or lost in the bush!  

 Here is our instructions if you want to try it:

Build a compass

1. Magnetize the needle
   Hold the needle, and take your magnet and stroke it down the length of your needle 50 times. If you are using a weaker magnet you may need to do this more than 50 times. But for most good quality magnets 50 should be about right.

2. Magnetize the other end with the reverse
   Now this is very important, take note of which side of the magnet you were using. Flip the needle around so you are holding the other end, and flip over the magnet so you are using the other side of the magnet. Now repeat on the non-magnetized end of of the needle.
   
   

3. Prepare the cork
   Cut a cork so it is about 1 to 2 cm thick.

4. Insert the needle
   Carefully push the needle through the cork. This is best done by an adult with a pair of pliers. I found it easiest if I used a thumb tack to start the hole, then pushed the needle through. You want the cork to be centered on the needle.
   
   

5. Fill a bowl with water
   Set out your bowl and fill it with a few inches of water.

6. Test the compass!
   Place your cork and needle in the water and see how it moves. It should align itself so it points North.
   
   

7. Extra fun!
   Create a second compass and add it to the same bowl of water. What happens? What happens if you bring your magnet near the water? What happens if you spin the compass?
