Surface Tension Steven Brignol Dr. Payne September 15 Introduction: Water’s ability to stick to itself is surface tension. In this lab we were able to measure and detect surface tension by dropping water‚ drop by drop‚ onto a penny. The quantity of droplets that fit on the penny was impressive. Hypothesis: The detergent will thicken the water making a tighter surface tension. Prediction: If soap increased the surface tension‚ then expansion will happen. Materials: (1) Pipette (2) Water

I don’t think this experiment should be replicated today. The reason being is that the Generation we have today has a different mindset and that the experiment is unethical in my view. In 1961‚ Milgram was able to make the participants agree with the experiment. These results led to people trying out these trails because the participants knew the shock would be painful but not dangerous. With that being said‚ it shows you the mindset of the people during that time. People were laid back and were

the experiment‚ the observational study and the survey. An experiment is a scientific method in which data are collected to be tested to prove a hypothesis using either independent variables in a closed environment or dependent variables in an opened environment. There are two types of experiment‚ the laboratory experiment that is as its name suggests conducted in laboratory and the field experiment conducted in a natural environment. The advocates of positivism support the use of experiment due

There were 3 main experiments that were conducted in the 19th century. The first experiment was conducted in 1928 by Frederick Griffiths. He was able to establish that there is a substance being transmitted from one generation to another. For this experiment Griffiths used two types of pneumococcus bacteria (the bacteria that is responsible for causing pneumonia). He used the smooth strain (S) which had an outer capsule that acts as a protective shield from the host’s immune system and rough strain

It is found that the deflection of the beam changes linearly with the load and as the beam

BSummary of Brain Asymmetry Introduction In the Brain Asymmetry experiment‚ the independent variable is the construction of the chimeric faces: one has the younger face on the left and the other has the younger face on the right. The dependent variable is the percentage of reports that chimeric face with the younger face on the left looked younger. The group of left-handed subects acted as a control group and helped to rule out the general left-view bias. It is hypothesized that percentage of reports

The Elvis Experiment Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel. Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect

Animal Experiment In present-day society‚ it is a well-known fact that animal experiments are playing an increasingly key role in our lives‚ and it is advancing at an amazing speed. Its research results have completely changed our lives. But in the meantime‚ the animal experiments ethics controversy has sparked much debate. Many people think that for the survival and development of humans‚ animal experiments are necessary. While some people argue that life of animals and humans are equally important

The Ten Most Beautiful Experiments The author of the ten most beautiful experiments‚ George Johnson‚ plays an important role in the book by writing it from his own perspective. Johnson is an American journalist and a science writer. He even cohosts "Science Saturday" which is a live online weekly discussion‚ clearly related to science. These facts could help readers know that the author knows what he’s talking about and has legitimate reasons behind each and every opinion he has.

Paragraph 1: The author opens his essay by introducing information that is logical to the reader. This is done by discussing the rights to know and live; while also discussing the pains that follow. Paragraph 2: This is where the author gives contrasting statements on how too much knowledge is not restricted. Instead‚ people
