• The steps of the scientific method are observation, define problem, construct a hypothesis, test the experiment/ gather evidence, and draw a conclusion. Observation is the procedure of collecting information about events and processes carefully. It involves with seeing and hearing. Defining the problem is when you identify a conflict that requires a solution to be solved. A hypothesis is a proposed explanation based on the evidence and observation. Testing the hypothesis is when we experiment and try to prove that our theory is correct. Gathering evidence is the process of recording the information gathered during the experiment. It includes quantitative

It is an experiment that tests density and gravity. The gravity is attempting to pull the tin foil and pennies downward, while the density determines whether if the boat will float or sink. If the object is denser than the water, the foil will descend. However, if the boat is less dense than the liquid, it will increase. As people know, foil is not the strongest material to build a boat out of so this will be a challenge.

Objectives
The intention of this lab is to use the scientific method to create a foil boat than can float and hold at least one hundred pennies. It is to demonstrate the buoyancy, or the ability to float in water, the boat built from the aluminum foil.

Materials
The supplies used in this Penny Boat Lab includes one sheet of tin foil (“12” by “12”), one hundred pennies, and a bucket of water.

Procedures
1. First, we designed a boat using only one sheet of aluminum foil, which it 12 inches by 12 inches.
2. Then, we placed our boat in the water, without the pennies, to see if the foil would float.
3. Our hypothesis is that our boat will hold ten pennies before it sinks.
4. After, we laid our boat in the water and began adding pennies on top of it one by one.
5. By the second penny, our boat began taking in water and started to descend to the bottom of the bowl.

    The data from the experiment must be noted and collected. Then the next step is to analyze the data. If the experiment doesn’t work correctly, the person needs to go back and double check he performed the procedure correctly. If the experiment was performed correctly and the data came out right, the next step is to draw a conclusion. If the results aligned with the hypothesis, the last step is to communicate results.…

    The eighth step of the scientific method is to draw a conclusion and report the findings. The final report should include what has been discovered through the research and any problems that were encountered during the process. The research should share the work to teach others about the findings and so others can read, respond to, and analyze the findings. This is an important step because it allows others to respond and critique the research. Sociologists use the scientific method to remove bias, observe the differences in common behavior, and to share their findings with others.…

    5). The hypothesis is a suggested explanation or preliminary idea of how something works, many call it an educated guess or possible explanation for something, which should be able to be tested and needs to be able to be proven false if necessary. This is a cyclical process, where more hypotheses can be added and determined as the theory develops (p. 8). A theory must be able to generate research, be able to be organized or categorized as well have the ability to give a platform or structure to ‘guide actions’, like using the ‘if this then, what?’ notion (Jameson, PPT). For example, in order to find a workable answer a psychologist could ask: if the patient suffers from low self-esteem and melancholy, then…
