1) We could not control the amount of water on the penny.
2) this is important because the point of the experiment is how many drops the penny can hold
3)

# data[].attributes.body
We did not control the amount of drops each coin could hold.  This variable is not meant to be controlled because it is the dependent variable. We could have controlled this variable by making bigger or smaller drops depending on if we wanted there to be more or less drops on the coin.

# data[].attributes.body
1) amount of water dropped on penny
2) no, because its needed for end results of experiment
3) put the same amount of water drops on the pennies

1) In the lab, we did not control the amount of soap used in every experiment.
2) If you were to compare the experiment with that of others, it would be important to control the amount of soap in all of the experiments.
3) If you could accurately measure the amount of soap in everyone's experiments, the variable would be controlled.

1. We didn't control how big or small the drops out of the pipette were.  We also didn't control our speed of releasing the drops.
2. It can be important if you are really want to be accurate since it would only affect your outcome of drops by 2-5.
3.  We could pay more attention to how fast and much water we dropped and take our time rather than rush.

Control the speed of the drops
If you drop the water fast it might break the surface tension
Get a machine to drop the water at the same height and rate.

1. We did not control the size of the pipette
2. It is not important to control, because it is irrelevant to the experiment
3. You could buy/make pipettes that meet your standards

# data[].attributes.body
1. The size of the drops of water were not controlled in the lab.

2. This variable is important because we can't determine the exact amount of water on each penny.

3. We could control the variable by using a machine to weigh each little droplet of water.

# data[].attributes.body
1. Size of the water droplets
2. Yes, because the water droplets being different sizes could affect the amount of drops that you can fit, and it is different every time.
3. A machine would drop the water droplets for you or something like that so it would be the most accurate it could be.

# data[].attributes.body
1. The size of the coin
2. It is important because it affects the amount of water on the coin.
3. Can control the speed of the drop.

# data[].attributes.body
1. We did not control the angle of the pipet very well, and it wasn't until the last test when we realized the differences in angling our pipets.
2. This was an important factor because it played a factor in the amount of water in each drop.
3. We could control this variable by being more aware of the angle of each pipet.

# data[].attributes.body
1. We could not control how clean the penny was.
2. This variable is important because it could affect the amount of water that the penny could hold
3. We could control this variable by using a cleaner penny

# data[].attributes.body
We did not control the surface (dirt level, dents, etc.) of the penny. This variable is important to control because it could affect how many drops are placed on the penny. We could control this variable by using a newly issued penny and/or cleaning the penny before using it. We could also use the same penny for both types of water in order to make the results fair/equivalent.

0. Don't write your name!
1. What variable did you NOT control in the lab?
2. Is this variable important to control? Why/why not?
3. How COULD you control this variable?
