Hello, I am just wondering if somebody can help me with some assignments? The first one is a water experiment. I have to turn everything in by the 11th.
This one is a lab report on water and some of the questions to help are
How do different materials affect capillary action?
How does adding salt affect the freezing point of water?
How does temperature change affect water's cohesion?
How does temperature change affect surface tension?
And this is the lab report layout
Title:
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.
Hypothesis:
Variables:
Independent Variable:
Dependent Variable:
Controlled Variable

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.
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.
