Reading Week 9

scientist. I drew my scientist like this because most scientists are men

principal. I drew the principal like because our principal is a male.

Prime minister. I don't know why I drew the Prime minister like this.

In our group the others drew the Prime minister like Jacinda Arden but I just did random

What is a gender stereotype? A gender stereotype is someone that thinks certain genders that has to do or like certain things.

I don't think jobs have certain stereotypes.

I don't think different aged people will draw the same things because their influence is different.

If I drew this again it would probably be different.

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 Image result for cornflour

2. Baking Soda Image result for 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. cardboard
2. sugar
3. salt
4. cornflour
5. baking soda
6. pen
7. magnifying glass

Steps

1. get a piece of card
2. split it into four groups
3. put all four ingredients on card
4. look at with magnifying glass
5. experiment with
6. Done

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	grains	Grains	bits	bits
Texture	block	blocks	soft	soft
Smell	sweet	gross	disgusting	nothing
Iodine	turned brow and spread	turned brow and spread	went solid	turned purple
Water	wet	wet	soggy	gross
Vinegar	wet	wet	fizzed	dissolved

Write a sentence about your findings.

I found that it depends on what chemicals and substances you use

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.

Sherbet recipe

Recipe:

Today for maths we did a group task in DMIC math. Our task was had to choose one of two people for there pay for 2 weeks. Person 1 got 10 dollars for the first day and got 2 dollars every other day and got 38 dollars all up. Person 2 got 1 dollar on the first day and it doubled every other day they got 8192 dollars. How we worked it out is we started with 1 and we kept doubling it until we had done it 14 times.

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

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1) Cup

2) borax

3)string

4)hot water

5) 3 pipe cleaners

6) stick

Process

Step 1: put 3 spoons of borax in the cup

Step 2: insert hot water

Step 3: stir with stick

Step 4: put stick on top of cup

Step 5: tie string on and twist 3 pipe cleaners

Step 6:tie pipe cleaners to string ad inset pipe cleans into the cup and wait

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) string

2) water

3) cup

4) sugar

5) stick

Process

Step 1: put 4 spoons of sugar in

Step 2: insert hot water

Step 3: stir

Step 4: tie string to stick

Step 5: put stick on cup

Step 6: wait

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) string

2) water

3) cup

4) salt

5) stick

Process

Step 1: put 4 spoons of salt in

Step 2: insert hot water

Step 3: stir

Step 4: tie string to stick

Step 5: put stick on cup

Step 6: wait

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	still like a star	same	hard
Sugar	same	same	hard
Salt	same	same	hard

What crystals worked out best and why?:

Conclusion:

________________________________________________________________________

After watching the videos as a class, explain how the following crystals are formed:

Type	Explanation
Salt	seawater, pond, sun, evaporation, salt
Sugar	sugar cane, chop it up, squish, juice, heat up juice to evaporate water, crystallises
Snowflakes	dust, water freezes to dust. more water freezes.
