Title: Does a penny hold more drops of water with soap or without soap? Objective(s):
Identify the purpose of your investigation or the question you are attempting to answer. Be sure to tie in the property of water you are testing.

Does a penny hold more drops of water with soap or without soap?

Safety Notes:
• Always have parent(s) or guardian(s) permission and supervision when performing a lab activity at home.
• Wear proper protective clothing and eyewear when needed.
• Be sure to dispose of all materials properly.
• Always wash your hands carefully after touching anything in a lab investigation.
Hypothesis:
I believe that the penny will hold less water drops with soap then without soap because the soap will disrupt the surface tension of the penny.
Variables: penny, water dropper, plain water, soapy water
• Independent Variable: penny and water dropper
• Dependent Variable: plain water
• Controlled Variable: soapy water

Materials:
2 penny’s, 2 water droppers, water, soap
Procedure:
The procedure should be clear and detailed so that others can repeat it. The details should be specific in how the procedure changes the independent variable, controls all variables that need to be controlled, and observes or measures the resulting changes to the dependent variable. You take 1 penny and 1 water dropper and add water without soap to the water dropper then keep dropping water droplets on the penny until it starts to spill then take another penny and another water dropper the take water add soap to it then start dropping the soapy water droplets onto the penny until it starts to spill off. This changes the independent variables by taking the water dropper and apply the dependent variable (water) into one of the droppers and adding the controlled variable ( soapy water ) to the other dropper and this also changes the controlled variable by adding it to one of the independent variables and this also changes the dependent variable by applying soap to it to make the controlled variable and it also changes the dependent variable by putting it inside one of the independent variable (water dropper) to apply it onto the other independent variable (penny).

Data and Observations:
Present all data and observations in a neat and organized manner. Include tables and graphs where appropriate/possible.

Conclusion:
Be sure to answer the following reflection questions as a summary in the conclusion of your lab report:
• Was your hypothesis correct? Why or why not?
• What were the results of your experiment?
• What changes would you make if you were to repeat the experiment?

Questions:
Using what you have learned in the lesson and the experiment, answer the following question in complete sentences.
1. Analyze the property of water you investigated and provide some real-world applications of the importance of this property of water.
