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

DNA STRAND
an individual activity
Materials:
2 black pipe cleaners
pony beads in 4 colors - (A, C, T, or G)
Instructions:
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.
Materials:
Index cards - with one letter on each (A, C, T, or G)
Rope - 2 long pieces
Instructions:
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.
