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

The Stanford Prison Experiment During arrests the police use procedures that lead people to feel confused and fearful. In the case of the Stanford experiment when the prisoners were arrested a process of humiliation began. The twelve undergraduates selected to play the role of prisoners were fingerprinted‚ mug shots were taken; they were searched‚ stripped naked‚ deloused and their heads shaved. Then they were dressed in cheap smocks‚ with no underwear and had a small chain around one ankle.

Experiment 5 Polytropic Expansion of Air Object The object of this experiment is to find the relation between pressure and volume for the expansion of air in a pressure vessel – this expansion is a thermodynamic process. Introduction The expansion or compression of a gas can be described by the polytropic relation ‚ where p is pressure‚ v is specific volume‚ c is a constant and the exponent n depends on the thermodynamic process. In our experiment compressed air in a steel

involved when two incompressible substances are mixed together. 12 experiments were performed‚ 10 involving the combination of a measured amount of hot and cold water and 2 involving the combination of ice and liquid water‚ the majority of these experiments were performed three times. The average variance in final temperature for each experiment was less than 10 percent providing proof of repeatability. Equipment used during the experiment included a gram scale‚ thermocouple‚ Styrofoam cup‚ glass beakers

The Rocky Shore Experiment Research Question: How does type of substrate affect the variation of species and vegetation as you move away from the seashore at a Rocky Shore? Hypothesis: As we get further away from the seashore‚ there would be a decrease in the number of species and vegetation found. Also‚ the type of substrate will have a major affect on the biodiversity. Background Information: A rocky shore is an intertidal area of seacoasts where solid rock predominates. Rocky shores are

The aim of this experiment was to replicate the Primacy effect‚ which investigates the effects of ascending and descending performances on attributions of intellectual ability‚ illustrating that individuals’ perception of another individual is influenced by their first impression of that person to the detriment of all subsequent impressions. The design included independent groups‚ and the 46 participants over 16 years old (25 males and 21 females) were chosen through convenience sampling. The latter

This assignment called for me to pick three out of four sensory experiments to conduct and then record my reaction to each experiment. The three experiments I chose to conduct are number one- the sandpaper experiment‚ number three- the index cards and flashlight experiment and number four- the water in bowls experiment. While conducting each of these three experiments I was surprised by the results of each of them. Experiment Number One: I rubbed my finger on the piece of coarse sandpaper and

Discussion: Conclusions: • For both meters it was noted from plots that the difference in pressures are directly related to the rate of discharge. • Coefficient of discharge have a varying value depending on the rate of discharge‚ where in the Venturi meter the value of Cd increase gradually at first with increasing the rate of discharge till a point approaching one‚ then started to descend with further increment in the rate of discharge. • The Coefficient of discharge " Cd

given crop? In our experiment‚ we examine the effects of water on corn. Corn is a vital crop to North America‚ and there is a wide draw to maximizing crop yields. To determine the effects of different amounts of water‚ we tested plants with various watering times according to a schedule. All of the plants experienced all of the same conditions‚ except for the quantities of water
