(Sodium Carbonate Solution): Dark Green 8-10 Base Test Tube F (Sugar Solution): Purple 7 Neutral Our results showed the clear color change as pH increased‚ transitioning from pink to purple to green to yellow. This develops a basic scale for us to base observations on‚ as a benchmark was developed. The pH of the substances in part C were unknown‚ and as such color changes were observed‚ allowing us to estimate the pH of the substances (see discussion). However‚ based on the scale‚ it is agreeable that

The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific

During the process‚ positively charged ions (Cations) more towards the electrode whilst negatively charged ions (Anions) move away.

The experiment is about strong and cheap table which the structure of honeycomb used to build it. A table using the honeycomb structure and also looks like real wood in a high quality and inexpensive. The table which is made from real wood mostly it is expensive and costs high. However‚ it is very strong. There are many people who can not buy them and search for the cheapest table. Moreover‚ the cheapest table is usually made from a lack of high quality material such as plastic and these are alternative

I choose this experiment because i like doing stuff( projects‚ experiments.) in sports. I think this is a good experiment is a really fun and it falls good in the topic. I also chose this experiment because i think it’s really easy to do by yourself and i have all the materials to conduct it. i also chose this experiment because i’m kind of like an expert in this topic because i have been in football for like 3 years so i think i know alot about the balls grip and how it affects the length. I think

HOFLING HOSPITAL EXPERIMENT Hofling 1966 He wanted to see if nurses would follow orders given by an authority figure (Doctor) when the orders are given over the phone and would be breaking regulations. To study obedience in a real life setting. -The experiment involved public and private hospital wards. In Hospital ONE; 21 student nurses and 12 graduate nurses were asked to complete a questionnaire asking them what they would do if confronted by the experimental situation. This was to be the control

Meselson–Stahl experiment From Wikipedia‚ the free encyclopedia The Meselson–Stahl experiment was an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported the hypothesis that DNA replication was semiconservative. In semiconservative replication‚ when the double stranded DNA helix is replicated each of the two new double-stranded DNA helices consisted of one strand from the original helix and one newly synthesized. It has been called "the most beautiful experiment in biology.[1]"

through hemolysis experiments ^^^^^. The human RBC osmotic content is about 0.9% NaCl. In hypotonic solutions‚ the cells swell because of water influx and eventually they hemolyze where cell contents including hemoglobin are released into the medium. This can be indicated by the change from opaque red cell suspension into transparent pink solution. Placing the cells in a medium containing permeating solute particles increases osmotic concentration and results to observable changes. Therefore the purpose

discussion I would like to contrast controlled laboratory experiments and naturalistic observations research methods. In controlled laboratory experiments‚ the researchers conduct their studies in a controlled setting. Conversely‚ studies involving naturalistic observation‚ examine participants in their natural environment. Below I present a contrast of the most essential features of each of these methods of research. Controlled laboratory experiments: • Objective: Seek to compare two or more conditions

Role Playing and its Toll In “The Stanford Prison Experiment‚” psychologist Philip G. Zimbardo describes his study of how placing average‚ male‚ college students in a prison like environment proved that their roles dehumanized them as individuals by radically changing their perceptions and behaviors. Before the experiment‚ the subjects were “emotionally stable‚ physically healthy‚ mature‚ law-abiding citizens” (734). With the flip of a coin ten men were chosen to be prisoners and eleven men
