W.A.L.T:Round numbers to the nearest 10,100,1000

For the week I have been learning Round numbers to the nearest 10,100,1000, I have learnt this before but it was a good way to refresh my brain.

I struggle at the start because I didn't remember but when I did I had it in the bag. This was easy once I got it I could complete one question in a few seconds. This was really fun to learn cause I had fun with my group.

Home chemistry 3.

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

Hypothesis: (What do I think will happen) 
I think that the vinegar and baking soda will make the bigger balloon.


Materials:

1.  Vinegar ½ cup
2. baking soda 3 tsp 
3.  salt 3 tsp
4. soda water ½ cup
5. yeast 2 tsp
6.  sugar 1 tsp
7. x 3 bottles
8. x 3 ballons
9. funnel 

Steps:

1.  get your bottles and balloons
2.  get your ingredients
3.  add ingredients
4. watch 

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)	14.7cm	8.6	12.8 cm
Bubbles	small amount	small amount	large amount

conclusion:

My hypothesis was correct that the baking soda and vinegar created the biggest balloon. It was really cool to see the baking soda go into the vinegar and fill up the ballon.

At the end of it, all the balloons were different coloured and they were all different sizes. The smallest was the salt and soda water was the smallest it is very interesting how different the size is. 

I learned that gas can fill a balloon. I also learnt that the largest balloon makes less amount of bubbles.

Lost storyboard

Today we had another session on our Art Hurumanu. Today we learned about, how to do stop motion, puppetry and whiteboard stop motion. We learnt about the different camera angles and new names like 'Annotation' which in the storyboard. Small notes and basically a small note telling you what is happening.
So we worked in groups of four to create a storyboard. I worked with Emily, Maia, Lucy, Heaven and Jasmine. But before we did that we picked something out of the brainstorm that other people did.

Home chemistry 2.

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. Cup

2. Felt pens

3.Chromatography paper

Process:

Step 1: Get Chromatography paper and a cup

Step 2: Draw line with pencil 1cm from the edge 

Step 3: Pick two colours (preferably dark)

Step 4: add water and watch

Conclusion: What have I learnt from this experiment?

I learnt that if you add felt to Chromatography paper with water it will go up. I also learnt that the colour will change colour as it goes. My group picked two colours green and dark blue. The dark blue turned purple then went blue. Then the green went green to blue. This was a really cool experiment and I want to do it again. But maybe in other colours. Maybe with lighter colours and see what happens.

Skittles

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

Materials;

1. skittles
2. petri dish
3. water


Process:

Step 1: get a petri dish
Step 2: get skittles 
Step 3: put skittles in petri dish
Step 4: add water to petri dish and watch.

Conclusion: What have I learnt from this experiment?
That if you add water to skittles it will get the colours out of it. The skittles loses its colour and goes white. I learnt that skittles taste disgusting if they are wet. Also, the water is disgusting. It was really fun. I would want to do this again cause of the skittles.

Home chemistry 1.Introduction

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) Salt

2)Lemon juice

3)Sugar

4)Vinegar

5)Lemonade bubbles

6)onion gas

7)Baking soda

8)Milk

9)Flour

10)Banana

Steps:

1.aim
2.step

3.materials

4.conclusion

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	Images	Solid/Liquid/Gas
Salt Lemon juice Sugar Vinegar Lemonade bubbles onion gas Baking soda Milk Flour Banana	Sodium Chloride citric acid monosaccharides acetic carbon dioxide syn-ropanethial-S-oxide sodium hydrogen carbonate magnesium hydroxide amylose potassium		Solid liquid solid liquid gas gas solid liquid solid solid

CONCLUSION: ( WHAT DID YOU LEARN OR SEE)

I learnt that salt I know the rules in a lab. I've learned that you have to listen so you know what to do. I learnt that salt is Sodium Chloride and it's solid. I've learned that a lot of products that I use at home are named a lot of other things. I also learnt that bananas are potassium. I also learnt really big names. I learnt that sodium chloride is solid. I also learnt that milk is magnesium hydroxide. I also learnt that onion is a gas. I also learnt that vinegar is acetic.
