Detailed explanation-1: -Conclusion: Use your data to answer your experimental question. The results indicate that when you drop water on a penny that the heads side of the penny will hold more drops (heads 23 drops, tails 18 drops).
Detailed explanation-2: -One reason that this happens is because of a property of water called cohesion. Cohesion is when two molecules that are similar to each other stick together. Water molecules are the same, and so they stick together and help keep drops on top of the penny.
Detailed explanation-3: -The answer to the purpose of this expirement is that with just regular drops of water pennies can hold an average of 30.25 drops of water. When the water is tampered with and mixed with a soapy solution the Penny does not hold as much water.
