Navigating using pin and magnet

Hello, everyone, I hope you enjoy my blog post

AIM Today in science we were learning how to navigate using pins and magnets.

Materials

For this experiment you need:

• Magnet
• Pin
• Small leaf
• Ice cream bucket
• And 2cm high water 

Steps

These are the steps that you need to do this experiment:

1. First, you need to grab your materials
2. You need to fill your bucket up with water only 2cm though
3. Then you need to put your small leaf in your bucket so it floats
4. You stroke your pin on your magnet only one way for three mins
5. After the three mins, you put your pin on top of your leaf

Then wait for your pin and leaf to face north.

It is a really fun experiment I Recommend trying it.

Compass

 The first compass that was ever made was in 1040 to 1044 it was made out of an ore of iron called a lodestone. It was made by William Thomson 1st Baron Kelvin in the ancient Han Dynasty. The directions that were on the compass were north east south and west we could tell where east and west were because the sun rose in the east and sets in the west. 

Deviation. When the bar magnet or magnetic compass is acted upon by a magnetic field other than the earth's, the magnet deviates. Most metal objects or electrical fields produce a magnetic field that will cause the compass to read incorrectly. This effect is known as a deviation.

Rocks are supposed to be kept away from compasses because they are magnetic.

The three jobs that still use compasses is military mining and piolet. You need a compass for these to be able to find your way around the place.

The three sports that need a compass is Hunting Orienteering and sailing. sailing you need a compass to navigate what direction you are going. Hunting you need a compass to find where your hunting trap is and orienteering for reasons.

Hurumanu 1

 In hurumanu 1 we have been learning about schools in ww1. In schools they taught skills strategy and combat. I have always wanted to know what it would be like if i was a student a school in world war 1. When I was younger I always thought that if I was in the war back in 1914 what would I do.

WW1 Memorial

 Hi

In hurumanu, we have done research of the WW1. The WW1 is a battle of the country, the New Zealand fight to so they will not be the target of the enemy. They fight each other, the country is fighting until the end. The New Zealand soldier had 8000 dead armies and 42000 wounded. The dead people we didn't bring there body's back to New Zealand so the memorials like they grave.

The memorial it's has all the names of the army who died in WW1, and every of the army has the name to the rock there named is the one who saved New Zealand.

We make our own memorial it's a drawing but the other it's a goggle draw, I did a google drawing. This is my memorial draw, the other student make this too, to the paper and to the goggle drawing. They do it too.
