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

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

Materials

3. Sugar
4. Salt Baking soda
5. Cornflour
6. Magnifying Glass

Steps

1. Get black Paper
2. Draw lines
3. Write sugar salt corn flower Baking soda
4. Put them on the black paper
5. Look at it with a magnifying glass

Findings:
