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.  Salt
2.  Baking soda 
3.  corn flour
4.  sugar
5.  
6.   
7. 

Steps

1. get your paper.
2. get your ingredients.
3. put the name of your ingredients.
4. put the water or vinegar in the ingredients.

Home Chemistry - Crazy 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

Process

Step 1:Get your cups with your ingredients.
Step 2:Get your Hot water and put in the cup with the ingredients.
Step 3:Mix your hot water and with your ingredients.
Step 4:Get your stick and put your string in the stick and put your pipe cleaner.
Step 5:Put your name.
Step 6:Put in the tray.

Sugar Crystals

Grow your own Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water
Materials

1)Sugar.

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


Type
Explanation
Salt
sea water,pond,sun,evaporates water.


Sugar
sugar cane,chop it up,squish/roll,juice heat,evaporate water,sugar crystalises.


Snowflakes
dust,water freezers to it.
