will give 90 or so points! I need help asap!
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.
Background Knowledge:
Polarity and hydrogen bonding are two key factors that contribute to the unique properties of water.
Safety Notes:
Always have parent(s) or guardian(s) permission and supervision when performing a lab activity at home.
Wash your hands before and after handling lab materials.
It is important to always protect your eyes during lab activities. Wear protective goggles whenever possible.
When working at the kitchen counter or table, be sure to protect the workspace from spills and immediately clean up any splashes or spills.
All materials in this lab activity are safe to dispose in the garbage (solids) and down the drain (liquids only).
Experiment:
Title:
Objective:
Hypothesis: I believe this penny would contain greater drops of regular water since the surface tension of the liquid would be disrupted by the addition of soap.
Variables:
Independent Variable: Water dropper as well as a coin
Unless Otherwise Noted All Content © 2021 Florida Virtual School
Dependent Variable: Normal water
Controlled Variable: Water with soap
Materials: Water, Soapy water, Water dropper or cup and a penny
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.
Data and Observations:
Present all data and observations in a neat and organized manner. Include tables and graphs where appropriate/possible.
Investigative Reflection Question:
Conclusion:
Include the following as a summary paragraph in the conclusion of your lab report:
Analysis of the results of the experiment
Rationale for the support or rejection of the hypothesis
Description of how the investigation could be tested further
Conclusion:
Questions:
Answer these questions in complete sentences using evidence from your investigation.
The properties of water are an essential part of what makes water unique. What affect does the properties of water have on Earth’s surface and its systems?

How does water’s molecular structure affect solubility of substances on Earth? Provide a real-world example.?
Explain how all the properties of water are related. Provide an example to describe the interconnectivity of each property. Be sure to include hydrogen bonding, polarity, surface tension, capillary action, cohesion, adhesion, high specific heat, and expansion upon freezing.
I chose the plain water and soapy water experiment.
