for week 9 my group was luring about kuri a type of dog that 2 thousand year ago my group had to answer question the out teacher set up for us here a little slide that.↟

Have a good day. 🐶

What is that white powder?

Today you will be a forensic chemist. 

A bag of white powder has been confiscated by the airport customs.  You need to find out what white powder it is?

Aim: To learn about the makeup of different white powders.

There are  a number of different white powders in our everyday life. Some of these are harmful and others are not. Test the four white powders listed to see which one has been found at the airport.

Here are some examples of everyday kitchen white powders.

Flour, Cornflour, Sugar, Salt, Baking Soda, Baking Powder, Icing Sugar, Tartaric Acid

Citric Acid, Gluten Free flour

You will be given a small amount of 4 white powders on your cardboard. On the black cardboard using a magnifying glass look at the powders.

Look at them under your magnifying glass and record what you see. 

These are the four powders we will be using. Upload a photo of each powder. 

1.  Cornflour
2.  Baking Soda
3.  Salt
4.  Sugar 

Before you add the iodine, vinegar or water you will need to divide each powder into 3.

Materials

1. powder 
2.  black paper 

3.  water
4. iodine 

5. vinegar

6. pipette 
7. 

Steps

1. put the powder on the paper 
2.  then put them is three groups
3.  then grab all the liquid you need
4.  then put the first liquid in all the salt or the other you can pick
5. then put the second liquid in all the sugar or the other you can pick
6.  then out the third liquid in all the baking soda or the other you can pick
7. then out the fourth liquid in all the cornflo or the other you can pick

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	crystal	crystal	fluffy mess	crambly
Texture	soft stons	hard	soft	soft fluffy
Smell	sweet	nothing	nothing	nothing
Iodine	spreed	went brown	went yellow	went black
Water	went clear	went clear	went clear	oobleck
Vinegar	watery	stay the same just a bit of water	fizzy	went hard

Write a paragraph about your findings.

Making Sherbet

Once you have completed your blog and cleaned up all your equipment you can make sherbet.

Using the following recipe you can make sherbet.

6. then shut the zip lock bag and mix's 

Findings:

Sherbet
Taste	weird
Colour	pink

Conclusion

First reading blog

Hi welcome to my bold we have been doing reading.

colourful experiment

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

Definition: A technique for separating the different parts of a mixture / solid using liquid.

Rainbow paper

Materials;
1. cup

2.  you need filter paper or special paper

3. water from sink 

4. the colours you need black green and red

Process:

Step 1: get a cup 

Step 2: get some water
Step 3: get the paper

Step 4: bend the paper a little at the top then put the hook on the edged and it should sit there 

Findings: the colour went up the paper

Reflection: the water can go up paper 

Skittles

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

Materials;

1. Small  Circle containers

2. skittles 

3. water from sink   

Process:

Step 1: spreed out the skittles 

Step 2: pour some water in with the skittles

Step 3: wait for a little to see the water change colour

Step 4: when its done open the container 

Step 5: then take out the skittles

Step 6: then you can eat the skittles 

Findings: the colour fared away form the skittle 

Reflection: That skittle colour combined in the middle then we got to eat them    

What did the colours do?
Did the colours mix together?
Why or why not?

Extension:

What is another experiment you could do using chromatography and how would you do it.

Puppet fun day

Today in drama we where doing a puppet show our puppet show was a bit weird but also fun. Miss Tozer was laughing after we finished but i can't blame her it was funny. Here the video we did                                                      ↡   
HAVE A AMAZING DAY AND LAUGH AT MY VIDEO BYE.

Our DMIC maths

Today in our maths we did DMIC we had to become a person is the story and work out how much the kids will get money they will get in two weeks in my group I had Kya, Emily, Heaven, and me. My whole group chose the boy because he will get more money the then girl because she get 10$ but then she get two more dollars for how long she works there. The boy only  1$ for the first day the get payed double for how long he works there. Here what we had to do.                                                  ↡

Have a good day bye 😊 .

Home made Crystals

Aim: To learn about a saturated solution and how to make crystals

Definition of solution: 

A liquid mixture, when something is dissolved into a liquid (eg: sugar in water) 

Definition of saturated: 

Having or holding as much as can be absorbed of something (when no more sugar or borax can be dissolved into the water)

In groups of three you will make three different types of crystals and compare the results.

Borax Crystals

Step 2: put 4 teaspoon of borax.  

Step 3: then put hot water. 

Step 4: then stir the borax in to the hot water.

Step 5: tie the string to the stick

Step 6: tie the pipe cleaner to the string
Step 7: Place the string into the cup

Materials

1) sugar. 

2) polyester cup

3) teaspoon

4) hot water 

5) string
6) stick

Step 1: get a  polyester cup 

Step 2: put sugar in the cup

Step 3: put hot water in the cup

Step 4: stir the sugar in with the water

Step 5: tie the string to the stick 

Step 6: set it in the water

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Step 2: then put hot water in the cup.

Step 3: stir it to together.

Step 4: tie the string to the stick. 

Step 5: put the string in the water.

Step 6: then let it set.

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Snow flake,  Frosty.	Madinm.	Brittle.
Sugar	No crystals formed.	Small.	Weak
Salt	Frosty.	Small.	Hard.

What crystals worked out best and why?:

Conclusion:

CRYSTAL TYPES

AIM: TO LOOK AT THE 7 DIFFERENT TYPES OF CRYSTALS

Salt Crystals

Sugar Crystals

Borax Crystals

7 different crystal shapes

The 7 types of crystals

Type	Number of sides	2 examples	Image
Triclinic Definition:	6	house a box with a pont
Monoclinic Definition:	9	diamond a banker
Orthombic Definition:	5	rectangle
Trigonal Definition:	9	long house.
Hexagonal Definition:	8	tall box tall circle
Cubic Definition:	5	cube Square
Tetragonal Definition:	9	gem from a gam

Explain how the following crystals are formed?

Type
Salt	Soa water, pond, sun, evaporates water and the turns into salt crystal.
Sugar	Sugar cane, chop it up, roll it in to juice, heat elaporate water and then you have a sager crystal.
Snowflakes	Dust,water freezer to dust,  more water freezer to it.
