white powders

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.  Black Paper
2.  Red pen 
3.  Ruler
4.  Magnifier
5. Baking soda, Sugar, Cornflour,Salt
6. Iodine
7. Water and vinegar
Steps

1. Get the 4 powders 
2.  Get a piece of paper and divide it into 4 groups and put the 4 powders on each piece and label the paper
3. Look and examine each powder
4. come up with ideas on what  they look like, smell like and feel like
5. Write your ideas down

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	crystals	crystals	smooth	smooth,clay
Texture	crumbly	rocky	smooth	smooth,crumbly
Smell	sweet	plain	nothing	plain
Iodine	colour change	colour change	colour change	colour change
Water	wet	wet	obleeck	obleeck
Vinegar	wet	wet	fizz	wet

It looked weird to see cause u normally never see any of these powders and mixtures mix so it was cool to see what happened. One of my favourite parts of this experiments was when the water and cornflour mixed together because it made a  obleeck look and feel it was cool to see that because I never knew that, that would happen if u were to mix the two so it was a really cool to see.
