EXPERIMENT
Materials
200 Toothpicks
Timer
Tape
Controls
50 toothpicks per trial.
120 seconds per trial.
The same brand of toothpicks.
One toothpick broken at a time (except for Mutation Trial 2).
One toothpick broken into two pieces equals one reaction.
Broken toothpicks cannot react again. (Toothpicks can only be broken once)
The toothpicks are broken between the thumb, index, and middle finger (toothpickase).
Break two toothpicks at a time (Trail 3).
Tape the index finger and thumb. (Trail 2)
Independent Variable
A mutation on the enzyme that hinders its ability (Trail 2) -To tape the index fingers and thumb.
A increase in the enzyme's strength (Trail 3) -To break two toothpicks at a time.
Dependent Variables
The number of toothpicks broken.
The reaction
Procedure
1. Gather 50 toothpicks.
2. Place them in a pile on the table.
3. Choose one member of your group of 4 to break the toothpicks. They are the one and only "enzyme".
4. Using the "enzyme's" thumb and index finger on your dominant hand, break the toothpicks completely in half. Repeat this for 120 seconds and record the amount of broken toothpicks every 10 seconds. Break the toothpicks without looking.
5. Once broken, the "enzyme" must drop the toothpicks directly back into the same pile of unbroken toothpicks.
6. Choose one person to record the amount of broken toothpicks, the time (10 second intervals of 120), and a person to count the toothpicks during the reactions.
7. Repeat steps 1-6 except the "enzyme's" index finger and thumb must be taped together. Record your quantitative results. (Trail 2)
8. Repeat steps 1-6 again and allow the enzyme to break two toothpicks at a time. Record your results.
DATA AND OBSERVATIONS
Observations
The "enzyme" we chose was Mohammed, a boy.
The table we worked on was flat and smooth.
