Science Experiment

Image result for baking soda and lemon juice

           Fizzing and Foaming

We want to find out which liquids are acid,we know that when we combine baking soda with vinegar we get a fizzing  and foaming reaction. Our teacher told us that baking soda is a carbonate and vinegar is an acid.
I think…
lemon juice - fizz
tomato - juice nothing
milk - foam
water - nothing
tea - nothing
grape - foam
What we need
  • baking soda
  • 6 small containers
  • 3 teaspoons the same size
  • tomato juice
  • lemon juice
  • grape juice
  • tea
  • water
  • milk
What we will do
  1. Put in 1 level teaspoon into each of the 6 containers.
  2. Add exactly the same amount of liquid to each of the containers.
  3. Observe carefully to see if there are any changes, smells,bubbles or sounds.
The lemon juice did fizz with the baking soda, the tomato foamed a little, the grape juice foamed, the tea did nothing and so did the milk and water.
What Farah, Manish, Aryan and me  found out is that when you mix all of them together after they were mixed they don’t fizz or foam.
Science Idea

Baking soda, also known as bicarbonate of soda, is a chemical compound made of sodium, hydrogen, carbon and oxygen. It is an alkaline substance that is similar to a salt and it reacts to acidic substances, including most liquids. The reaction gives off carbon dioxide gas. It exists naturally in bile and neutralizes stomach acids. Baking soda is often used in baking, personal cleansers and science projects because of its ability to react chemically with acids.

Sculpture with Tinfoil

Today we had to make a person using tinfoil and we only had a small piece each.  Look at our mini people! We had to investigate how to do it ourselves

Maori Language Week

Whakanuia te wiki o te reo Māori - Celebrate Māori language week

Whāngaihia Te Reo logo.
The kaupapa for Te Wiki o te Reo Māori 2015 is ‘Whāngaihia te reo Māori ki ngā mātua.’
We aim to encourage and support the language development of parents who can then whāngai the language to their children.
Ngā mihi nui ki a koutou katoa. Greetings to you all.
Te Wiki o te Reo Māori /Māori Language Week takes place this year between Monday 27 July and Sunday 2 August. This special week provides an opportunity to celebrate and learn Te Reo Māori, helping to secure its future as a living, dynamic, and rich language.

Bubbling Lava Lamp

This term we are doing scientific investigations looking at 'Cause and Effect'. Our first experiment this week was to make a bubbling lava lamp.

We want to find out if oil, water, and aspirin make a bubbling lava lamp.
I think that the aspirin in the water will bubble then the food colouring will colour the water red.
A bottle
Vegetable Oil
1)Fill the bottle ¾ full with vegetable oil.
2)Fill the rest of the bottle but make sure it doesn’t overflow with water.
3)Add the food colouring in to make the bubbles a colour so you can see the bubbles.
4)Put the chopped up aspirins in and wait till it starts to bubble.
What happened was that the aspirins made the bubbles and since that the food colour sank to the bottom it made the bubbles the colour that the food colouring was.
What we found out that you need quite strong aspirins to make the lava lamp bubble.
I thought that the 1st aspirins weren’t strong enough and I was right.
Science Idea
The scientific reason for this experiment was seeing what happened when you mixed oil and water together in the same bowl/bottle.And the reason why the oil and water didn’t mix is because they have different densities.Oil is less dense than water so it sits on top of it.

Cameo Writing

Welcome back to Term 3!
This term we are going to be working on descriptive writing by using models of great writing and then changing parts of the writing to put our own images and descriptions to a similar theme. This is called 'Cameo Writing'.
Today we read a text called 'My Yellow World'.

Then we chose our favourite colour and did our own piece of descriptive writing. This is what Manish came up with. 

My Red World!

I live in a red mansion and have butlers with red suits.The place is so red that people call it a blood mansion with even a blood rooftop.I even have red underpants and have red trousers - actually  I wear all red and have strawberry onesies and slippers.My favourite thing to do in red world is swimming. I have my own blood  red pool with blood  red chlorine.I even have a rose and other red flowers  in my garden with a beaming red bright light.I eat red melted pizza with a ham and cheese topping with blood  red juice.In red world there is so much red - it reminds me of red berries.I have 2000 cars with roses printed all over them.I have red grass in my patio and red grass with a huge space for a water fountain and to play red sports and cricket and more sport games.
I love my red world because it is so red like my favourite superhero  ‘The Flash’. Maybe if  I wear more red clothes  I will become the fastest man alive.
