Procedure Part 1: Surface Tension of Water

Fill the 100 mL beaker with tap water so that the beaker is almost full.
Hold a needle vertically, as close to the water in the beaker as possible without actually touching the needle to the water.
Note: Vertically is up and down in direction; imagine the post of a stop sign.

Gently drop the needle onto the water.
Record the observations in Data Table 1 in the row labeled "Vertical."
Carefully retrieve the needle from the water and dry it.
Note: The needle must be completely dry between each step. If you would like to repeat any steps, make sure to dry the needle before you begin.

Hold the needle horizontally, as close to the water in the beaker as possible without actually touching the water.
Gently place the needle onto the water.
Note: Do not drop the needle at an angle.

Record the observations in Data Table 1 in the row labeled "Horizontal."
Drain the water from the beaker and dry both the beaker and needle.
Part 2: Breaking Surface Tension

Place a paper towel on a flat surface.
Place the 2 oz.– 8 oz. cup or drinking glass on the paper towel.
Note: Do not use the 9 oz. cup included in the lab kit materials.

Fill the cup or drinking glass just above the brim with tap water without allowing the water to overflow. See Figure 6.
Predict how many paper clips can be added to the cup before the water overflows. Record the prediction in Data Table 2.
Add paper clips to the cup one at a time while counting the number added. The paper clips will sink to the bottom of the cup. Add paper clips until the surface tension breaks and water spills over the cup.
Record the results in Data Table 2.
Drain the water from the cup or glass and then dry both the cup or glass and paper clips.
Part 3: Cohesive and Adhesive Properties of Water

Place a paper towel on a flat surface.
Place a coin of any type on the paper towel. Ensure that the coin is level.
Fill a pipet with tap water.
Predict how many drops of water you think can be placed on the coin before the surface tension of the water will break and the water will flow off the face of the coin. Record your prediction in Data Table 3.
Using the pipet, place 1 drop of water at a time onto the coin until the water flows over the face of the coin. See Figure 7. Count the drops as they are added and record the final number of drops in Data Table 3.

Dry the coin and remove the water from the pipet. Keep the pipet for use in Exercise 3.
Part 4: Capillary Action

Obtain 1 short, thin celery stalk with leaves.
Fill a drinking glass with ½ cup of tap water.
Add 1 mL of food coloring.
Cut the end of a the celery stalk diagonally and immediately place it into the colored water.
Allow the celery to remain in the colored water for 4 hours.
Note: If you do not see any change in the celery or flower after 4 hours allow the incubation time to continue.

When the 4 hours is complete, observe the celery. Record your observations in Panel 1.
