1 cup powdered sugar
1 cup granulated sugar
1 cup butter
1 cup oil
2 eggs
1 teaspoon vanilla
1 teaspoon salt
1 teaspoon baking soda
1 teaspoon cream of tartar
4 cups plus 4 heaping teaspoons of flour

6. Roll into balls. Flatten with fork on ungreased cookie sheets
7. Sprinkle with granulated sugar (skip this step if frosting then decorating)
8. Bake for 10 minutes
9. Frost and decorate if desired

NOTE: I sprinkle colored sugar through stencils cut from plastic milk cartons

In a closed ziploc bag, shake 1 cup granulated sugar with 6 drops food coloring

an individual activity
2 black pipe cleaners
pony beads in 4 colors - (A, C, T, or G)
1 Assign each color to a letter (G=green, C=Red...)
2. Bend the bottom of one pipe cleaner into a hook so the beads don't fall off. String beads on one pipe cleaner in any order
3. Carefully twist one end of pipe cleaners together
4. String second pipe cleaner so that A is paired with T on the opposite strand and C is paired with G.
5. Twist other ends of pipe cleaners together
6. Twist DNA into a double helix

DNA Pairing and Cell Division (DNA Replication)
A group activity suitable for a classroom
Before a cell divides, it must copy its DNA.
Index cards - with one letter on each (A, C, T, or G)
Rope - 2 long pieces
1. Put the two strands of rope in a straight line on the floor parallel with each other about 2 feet apart.
2. Arrange kids in a circle. Hand the kids an index card with a letter.
3. Kids form A-T and C-G pairs and line up in pairs between the ropes. Those on the left take the left rope in left hand. Those on the right pick up the right rope in right hand.
4. Now DNA has formed and it's time to divide. The group on the left marches leftward. The group on the right veers to the right separating the strand like a zipper.
