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

Gluten Free flour

Materials

1. corn flour 
2.  baking soda

5.  water
6. lodine
7. vinegar

Upload a photo of each powder.

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

On the black cardboard using a microscope you need to record what you see. You will be given a small amount of 4 white powders on your cardboard. Look at them under your microscope and record what you see. 
Do not mix the powders or taste the powders.

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	crystal white	little bits of white	chunky white	big chunks of white
Texture	rough	Rough	powdery	chunky powdery
Smell	nice	good	weird	bad
Iodine	wet and goes color on the iodine	light brown and dry	stains the little bit it got dropped on	bubbles
Water	soaks it in	does nothing	spreads	soaks it in
Vinegar	goes grey	goes grey	fizzes	fizzes

Write a paragraph about your findings.
Today we looked at what happens when you mix some chemicals with white powder you can find at home. the vinegar mostly made them go grey and fizz.  the water does nothing
and the iodine stains it

Scones

Aim: To look at different kitchen ingredients in scones and their effects.

                                     

You will be in groups of 3. Your group must have a group name.

You will each have a role for the first scone, then rotate roles for the next two.

Scone types:

1. No butter
2. No Baking Powder
3. No milk

findings

Trial	colours	taste	hight
normal	Crispy Gold	yum	40mm
lemonade	Goldy yellow	good	45mm
No baking soda and lemonade	Brown and gold	Really gross	46mm

Conclusion

When we did the taste test the first 2 were good

And the last was worse because it had no baking soda  we cooked them for 10 minutes at 200 degrees c
