Science

Aim: To see which chemical 
the mix creates the most gas.

Hypothesis: (What do I think will happen)
I think the 3 tsp baking soda, 1/2 cup vinegar well be the most balloon size.

Materials:

1.  baking soda
2.  Warm water 
3.  Sugar
4.  Yeast
5.  Bottle
6.  Balloon
7. Salt
8. Soda water
9. Funnel
10. Vinegar 

Steps:

1. balloon 1, we tack 1 bottle out, and we put 2 tsp yeast and 1tsp sugar in the bottle and put some warm water in, and put a balloon on the top, wait for 20 minutes.                                  
2. balloon 2, we tack 1 bottle out and put 3 tsp baking soda and 1/2 cup vinegar in the bottle and put a balloon on the top, wait for 20 minutes.
3. balloon 3, we tack 1 bottle out and 3 Tsp salt, 1/2 cup soda in the bottle and put a balloon on the top, wait for 20 minutes. 

My images:

                                                              

Findings:

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)	Balloon 3 ( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)	10.6 cm	5.1 cm	5.5 cm
Bubbles	small amounts	medium amounts	large amounts

Skittles

Aim: To separate colours from skittles by using the chromatography.

Materials;

1. Petri dish
2. 5 different flavour skittles
3. water
Process:

Step 1: tack a Petri dish, and put 5 different flavour skittles, and put some water in.

Step 2: and wait like 2 minutes and the skittles will like this.













Conclusion: What have I learnt from this experiment?
I learnt the 5 colour mixed together is Flesh.
And the candy is good.

science

Aim: To separate colours by using the process of chromatography.

Definition: Chromatography is a method of separating out materials from a mixture.

Eg. blood, ink, drugs,

Scenario

A crime has been committed. The police have a signed cheque and a letter from the same crime scene but it seems like the handwriting is different. They have 3 suspects but not enough evidence. They need to know if the letter and the cheque were written by the same person.

How do they tell if the pens used for both of these pieces of evidence are the same?

Rainbow paper

Materials;

1.  Chromatography paper

2. Felt pens

3. cup

4. water

5. pencil

Process:

Step 1: Tack the Chromatography paper and use felt pen draw two dots.

Step 2: Tack the Chromatography paper and use felt pen draw two dots.

Step 3:And put some water in, the water and wait for 10 minutes. 

Step 5: After 10 minutes

Conclusion: What have I learnt from this experiment?

I learned the paper can Water absorption. And the colour is like magic.

Art Hunumaru: Stop, Write, Hear

Today we have Art Hurnumanu, and we did Storyboard Shetches and we draw a story on the paper, and we are making like a boy stuck in the tree and we try to save him. And we are not really finished so later we will be doing better.

CIP

Today we are doing Tane mahuta and we need to choose what you do and I choose Gardening and we just pack some weeds and clean that space.

science

Aim: To learn the names of 10 household chemicals and identify if they are a solid, liquid or a gas.

Definitions:

1. Element; A single form of a chemical
2. Compound: A mixture made up of 2 or more elements
3. Reaction: A process in which chemicals mix together to form a new substance.
4. Mixture: When two or more elements are mixed together.

Equipment:

1. lemon juice   
2.  salt
3.  sugar
4.  vinegar
5.  Lemonade bubble
6.  onion gas
7.  baking soda
8. milk
9. cornflour
10. Bana

Steps:

1.search the name up

2.then put the image on the table

3.then find the name of each one acids name

4.then writ the name of each things acids on the table

Repeat the steps for all the chemicals.

Task 1: Put the 10 chemicals in a chart with the titles - Name, Chemical ingredient(s), Image, Solid/Liquid/Gas.

Name	Chemical	Image	Solid/Liquid/Gas
Lemon juice	citric acid		Liquid
Salt	Sodium chloride		solid
Sugar	Sucrose		solid
Vinegar	Acetic acid		Liquid
Lemonade bubbles	Carbon dioxide		Liquid
Onion gas	sulfenic acid		gas
Baking soda	Sodium hydrogen carbonate		solid
Milk	Lactose		Liquid
Cornflour	Cornstarch		solid
Banana	Appearance		solid

fAIM: DESIGN AN EXPERIMENT THAT TESTS THE AMOUNT OF SALT THAT MUST BE IN WATER BEFORE IT WILL NOT FREEZE WHEN LEFT OVERNIGHT IN THE FREEZER.

When we design an experiment there are some important questions that we must answer first. This is part of the planning stage and will help to give us some ideas.

Record these answers on your blog.

The Plan.

Task 1; Read the question carefully and write the answer to these questions.

1. What do we need to find out?
2. How will we find it out?
3. How will we record what we find?
4. What equipment do we need for the experiment?
5. How long will it take?

The Procedure

Task 2: What are the steps that you will take to make the experiment?

List them in 6 steps.

Step 1;

Step 2:

Step 3:

Step 4:

Step 5:

Step 6:

The Process

Task 3: Draw on a piece of A4 paper the 6 steps that you will use to test the amount of salt in water before freezing. When we are making drawings in science it needs to be labelled clearly, kept tidy and named. Once you have completed the drawing it must be photographed and uploaded to your blog.

In your drawing you will use:

1. Beakers
2. Water
3. Measuring spoons or cups
4. Salt
