point of water. I bet you didn’t know that! There’s a reason for that‚ but I’ll explain that a little later. First‚ let’s find out if salt can actually change the freezing and boiling point of water. To do so‚ we need to do an experiment. Now‚ if you’re going to do an experiment‚ you’re going to need a hypothesis. Let’s use mine. I said “if we know salt in the ocean’s water can affect its temperature‚ then I wondered if adding salt to regular tap water and bottled water would raise the water’s boiling

Yale University psychologist‚ Stanley Milgram‚ conducted an experiment in 1961 focusing on the conflict between obedience to authority and personal conscience. He examined justifications for acts of genocide offered by those accused at the World War II Nuremberg War Criminal trials. Their defense often was based on "obedience" - that they were just following orders from their superiors. Milgram’s experiment‚ which he told his participants was about learning‚ was to have participants (teacher) question

thousands of unconsented medical experiments on concentration camp prisoners. The experiments could be split up into three categories. Experiments aimed at facilitating the survival of military personnel‚ developing and testing pharmaceuticals and treatment methods for injuries and illnesses which German military encountered‚ and the final category was to advance the racial and ideological tenets of the Nazi worldview. The article describes a type of experiment that was part of the first section

Aim To investigate how parachutes work and whether size matters to performance. Background According to Agee (2010)‚ “As a skydiver is falling‚ the force of gravity is pulling them towards the earth… The parachute slows the skydiver down because it causes air resistance or drag. The air pushes the parachute back up‚ and creates a force opposite to the force of gravity‚ slowing the skydiver down.” Question We wanted to find out how the size of a parachute would affect its descent as we felt slowing

PLAN OF INVESTIGATION Fundamental Science Salt water egg experiment Result Some objects float on top of the ocean‚ and other objects sink to the bottom. Why? In this salt water egg experiment we can find a solution for this question. It was noted that to make the egg float salt is needed to dissolve into fresh water. When the egg was lowered into the fresh water container it started to sink. But when salt was added to the container the egg started to float. Adding salt

1932‚ the United States Public Health Service (USPHS) conducted an experiment in Macon Country‚ Alabama‚ to study the progression of syphilis in black males known as the “Tuskegee Syphilis Experiment”. During this experiment‚ medical professionals intentionally withheld treatment for syphilis after deceitfully promising these volunteers beneficial treatment to help combat the disease. Until this day‚ the Tuskegee syphilis experiment is an infamous clinical study in America’s history that delineates
