Connect the dots

In this lab, you will follow sets of instructions to investigate how clones work.

Part 1: All together now

Each of the six students in your group should follow these instructions. Each student should then follow his or her instructions, completing each corresponding step together. (For example, everybody should complete their step ii. at the same time.) Everyone should work on the same grid.

1. Put your pen on the first dot in the bottom row of the grid below.

2. Draw a line to the dot to the right.

3. Draw a line to the dot to the left.

4. Draw a line to the dot above.

5. Draw a line to the dot above.

6. Draw a line to the dot to the right.

7. Lift your pen.

   

What was the result of the group following the instructions? Were there any difficulties you encountered? Does it seem like the result was intended?

Part 2: To each his own

5. Draw a line to the dot above.
6. Draw a line to the dot to the right.
7. Lift your pen.

Person #2

1. Put your pen on the third dot in the bottom row of the grid below.

7. Lift your pen.

Person #6

1. Put your pen on the eleventh dot in the bottom row of the grid below.

5. Draw a line to the dot above.
6. Draw a line to the dot to the right.
7. Lift your pen.

Part 2 - Reflection

1. What was the result of following the instructions?
2. Does this seem like the most efficient way to achieve this goal?
3. What would happen if the shape needed to be changed?
4. What problems could that cause?
5. What might be a better or more efficient way to accomplish the goal of these instructions?

Part 3 - The same but different

Assign each member of your group a different number from 1 to 6. Each of the six students in your group should then follow these instructions. Each student should then follow his or her instructions, completing each corresponding step together. (For example, everybody should complete their step ii. at the same time.) Everyone should work on the same grid.

1. If you are person #1, put your pen on the first dot in the bottom row of the grid below.
2. If you are person #2, put your pen on the third dot in the bottom row of the grid below.
3. If you are person #3, put your pen on the fifth dot in the bottom row of the grid below.
4. If you are person #4, put your pen on the seventh dot in the bottom row of the grid below.
5. If you are person #5, put your pen on the ninth dot in the bottom row of the grid below.
6. If you are person #6, put your pen on the eleventh dot in the bottom row of the grid below.
7. Draw a line to the dot to the right.
8. Draw a line to the dot to the left.
9. Draw a line to the dot above.
10. Draw a line to the dot above.
11. Draw a line to the dot to the right.
12. Lift your pen.
