Sink or Float!

    This Experiment is called Sink or Float

     Equipment

     Plastic Container

     Water 2/4

    Table Salt

    Teaspoon

    Eye Dropper

    Clay

1) Fill the container 3/4 full with water

2) Put a small piece of clay around the bottom of the eye dropper.

   DO NOT BLOCK THE OPENING

3) Float the eye dropper in the water

4) Now squeeze the bulb of the dropper to let air out one drop at a time, testing after each drop to                          see if it sinks.

5) Once the dropper sinks, stir in teaspoons of salt into the water one at a time until it floats again.

Record how many tsps of salt it took to make the eye dropper float again.

Hypothesis: I think it will float.

It did not I think this was because of the smaller size of my container

We carried out a science investigation to find out what affect adding salt to water would have on an object that was weighted doing in water.

My Hypothesis: It would definitely float.

The investigation showed initially that adding salt made no difference. After adding and mixing 6 tsps of salt however the eye dropper did not float. Me and my partner altered our eye dropper by taking some clay off but it still did not work.

Technicraft - Making a Boom Box

At Room 8 we have been visiting Pakuranga Intermediate every Thursday. At the Intermediate we have been learning about electronics. For the past few weeks we have been building a Boom Box.

My Mum...

My mum... she is a lot of things, she is pretty, beautiful, unique and special. To me and my family her beauty is more radiant than the burning sun, she lights the world up even on sad days because she is my mum.

If I had to compare my mum with a single word it would be mine. I can say this because it is true and honest. It is hard to believe that I was so gifted to be the son of my mum and even though I don’t admit it, she is the best mum in the world.

When I need it she is always there for me even when I am not there for her. She has continued to give my brother and I the best guidance to the full of her ability and on rare occasions when I would cry she would comfort me and remind me that I always would have a ‘Happy Place’ in her.

She would never discourage me and never consider me a nuisance or distraction, she is always honest to me and I could give her my secrets freely because she is trustworthy .

The moment I came out of her tummy, she accepted me with open arms and a big white smile. She has a lot of perseverance because having faced nine months of pain and anxiety to bring me to the world, she is my hero.

I could write a whole series about my mum and it still wouldn’t be enough to explain how much she means to me, she is the reason I am alive, she is my Giver of Life and thats why my mum is always and truly forever special.
