8.  black paper and pencil and ruler
9.  a drop Vermonter.  
Steps

1.  line up the black paper with a ruler the squares 4 should be the same size.
2. write the one four names at the top of each squares names salt sugar baking soda cornflower.
3. tip two table spoons on one of the squares that is named but put the same powder with it name sugar with sugar.
4. separate the powers in to 3 piles.
5. now use the drop Vermonter and water on one pile on each of  
6.
