White Powders

Aim To learn about the makeup of different white powers.

There are a number of different white powders in our everyday life. Some of these are harmful and others 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, Cornflower, sugar, salt, baking soda, icing sugar, Tartaric acid, citric acid, gluten free flower

You will be given a small amount of 4 white powders on your car lard 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. Cornflower
2. Baking soda
3. Salt 
4. Sugar

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

Finding...

Whilst I was doing this experiment with my group we found a lot of things. We found out what the mystery powder was. Can you guess? IT WAS BAKING SODA. It was really easy finding out which was which as we did the vinegar and it made bubbles like the other one. We learnt a lot from this experiment as we never knew things but there was a lot of experimenting. How did your experiment go?
