WebDo this by adding the values for the three trials and then dividing by 3. For example, if your values for the plain tap water were 0.7 mL, 0.9 mL, and 0.95 mL, the average would be (0.7 + 0.9 + 0.95) ÷ 3 = 0.85 mL. If you need help calculating an average, ask an adult for help. Make a bar graph of your results.

Experiment: How many drops of water fit on a tiny penny?

http://labsci.stanford.edu/images/Surface-Tension-TA.pdf WebIt took 45 drops of water to over flow the surface of the penny. Procedure: What I learned performing this lab: I learned that cohesion caused the water molecules to “stick together” and pile on top of each other. By doing this, they formed something similar to a bubble to prevent the drops of water from spilling over the edge of the penny. darth vader no website
