Scientific Method Research Paper
What exactly does scientific method entail? The scientific method is a set of procedures used by
scientists to find answers to inquiries about or in relation to natural events. The main approach
used to acquire and distribute biological information is the scientific method. Despite being vital,
the scientific method's definition, use, and historical evolution are all poorly understood
(Blystone& Blodgett, 2006).
These are the steps that are involved in the scientific method:
Observation – careful and keen observation is essential in the scientific observation
When we observe we are likely to ask questions
Problem/Question
The problem or question is one that we develop that can be solved through an
experimentation
Observation/Research
During this step of the scientific method, you would make your observations then
research your findings related to your topic
Formulate a Hypothesis
In this step you will begin to formulate or predict the possible answer to the problem or
question you have been observing.
Experiment
You will develop and follow a procedure
In this step you will construct a materials list, the outcome must be measurable
Collect and Analyze Results
3
During this step of the experiment, you will change up any part of the procedure
necessary.
Confirm the results by retesting
Use pictures, videos, graphs, charts, or tables
Conclusion
During this step you will develop a statement related to the experiment that either
accepts or rejects the hypothesis
Make any recommendations or further studies to improve the procedure
Communicate the Results
Here you will present your findings be mindful of the feedback you will receive expect
questions and criticism related to the experiment from the audience and readers.
In this experiment I will test out surface tension theory
What you need:
A bowl
Water
Dish Soap
Ground Black Pepper
1.Ask a question: Surface tension is the potential for liquid surfaces that are at rest to condense
into the smallest surface area.AIn this experiment we will ask will surface tension change when
soap touches water.

2.ADo background research: Surface tension is what allows an object with higher density than
water to float on water without becoming submerged.A
3.AConstruct a hypothesis:Aif you change the surface tension of the water anyAa change occurs in
the water by adding another element such as soap on your fingertip.
4.ATest your hypothesis:
Step 1 The Set Up
The entire bowl with water should be dusted with ground black pepper. The pepper should be
sitting on the water's surface when you look for it. This is due to the fact that water has a high
surface tension, which means that water molecules are attracted to one another strongly and like
to cling together.

Step 2 Add the pepper / the control
Due to the pepper's small weight, it floats to the top of the water instead of sinking to the bottom.
Due to the pepper's hydrophobicity, which prevents water from being drawn to it, the pepper
does not dissolve into the water; instead, it just rests/sits on the surface. If you dip your finger
into the water, it will have no real effect on the pepper. some of the pepper might even stick to
your finger, but nothing else really happens.
However, if you place the dish soap on your finger then place that finger in the middle of the
water.

Step 4 The Results
The pepper should start to separate and dart away from your finger and toward the water's edge
right away.
5. Analyze your data
Due to the cohesive forces, liquid molecules at the surface pull molecules farther away from the
surface equally in each direction, resulting in a net force of zero.
7
The form of liquid droplets is a result of surface tension. Water droplets can be easily distorted,
yet they have a tendency to take on a spherical shape as a result of the surface layer's uneven
cohesive forces. A
6.Communicate your results
In conclusion when the surface tension changes as the soap comes into contact with the water,
causing the pepper to sink to the bottom. The water molecules, however, continue to strive to
maintain the surface tension, so they pull away from the soap while also dragging the pepper
with them.
