1. Place one-fourth teaspoon (1 ml) of the flour white powders on a sheet of black construction paper. Label the powders on your pen.
2. Study the powders with the magnifying glass. Examine what each powder looks like. How would you describe the powder's shape. Does it have large or small grains? Your observations should be written in the appearance column of the chart.
3. Examine the powders further by rubbing each powder between your fingers. Describe how each powder feels in the Texture column of the chart.
4. Determine if there is a smell to any of the powders. Record your findings in the smell of the column chart. 
5. Take the eyedropper and place a drop of water on each individual powder. Examine what happens? Do the powders dissolve? Is there a reaction? Write your observations in the Reaction to Water column.
6. Place on-half teaspoon (2ml) of each powder in a separate jar. Add 2 drops of iodine to each jar using the eye dropper. Record what happens in the Reaction to iodine column. Iodine should be handled with care.
