... to travel and so more collisions will occur. Due to this, the length increase should be directly proportional to the resistance increase. To measure and record the results for this factor is simple, the results would be collected and could show a connection between the length of the wire and the resistance given by ... keep colliding in the way and making the electrons use more energy. Preliminary Method In this preliminary experiment, I will use different lengths of wires to measure their resistance. The main idea of doing the preliminary experiment was to find a suitable current numbe...

... particles which allow more collisions to take place. There are various ways of measuring the rate of reaction: Collecting and measuring a gas product. However this can be very difficult to measure for this particular reaction because the gas produced in the reaction is Sulfur dioxide which will react with oxygen and react with the solutions to produce acid rain, which will dissolve ... the amount of Sulfur produced as a precipitate is too difficult to evaluate, it will always be the same for each experiment I carry out. So therefore I will take the reciprocal of the time taken for the S...

... the test tubes they each will be labelled. The potato pieces will then be placed in the different test tubes and then left for one day for osmosis to fully take place and be stored in a dry place by the teacher. Then the potato pieces will be removed, the ... Firstly I can see that the correlation of my graph has a high and strong negative correlation, meaning that as the concentration increased the change in millimetre for the potato decreases. This is because when the concentration is increased osmosis in a high concentration of water the amount of solute (e.g. sugar) is low. ... the...

... , therefore decreasing in weight and length. I predict that my graph will look like the graph above this because, the potato chip used for 0 molar concentration will gain water, as the water moves from a region of high concentration (the solution) to a region of low concentration ... suitable range to base my investigation round. In this experiment I used 3 chips in 3 boiling tubes, each containing 20cm3 of: 0M sucrose, 0.5M sucrose and 1M sucrose. My result for the preliminary experiment is shown below: Sugar concentration (M) Mass before (g) Mass after (g) Length before (cm) Length afte...

The research was conducted on a small sample of college students and a related measure design was used. The procedure involved the participants naming the colour of words in ... the colour. Procedure: 2.6. The researcher individually took the group members into a private room and using a pre-scripted text (See Appendix 1 for script) read out aloud the instructions and explained the purpose of the experiment. 2.7. The particular individual doing the experiment was then issued the indepe...

... possible conditions. The conditions consisted of the no eyewitness, discredited eyewitness, or refuted eyewitness. Twenty-nine participants were exposed to the no eyewitness condition. This experiment was to measure participant's degree of perceived guilt in one of the three conditions. Based on previous research in eyewitness testimonies it is hypothesized that the presence of an eyewitness testimony increases ... addition, seventy-two percent of participants who heard eyewitness testimony voted guilty and sixty-eight percent of the participants in the group where the eyewitness testim...

... has an effect on cognitive dissonance and if there's a correlation between how much a person drinks and their dissonance level. According to cognitive dissonance theory, there is a tendency for individuals to seek a balance between their beliefs, opinions and actions. When there is an inconsistency between attitudes or behaviors (dissonance), something must change to eliminate the dissonance. In ... hypothesis was tested in the first two experiments by having subjects taste and rate different brands of an alcoholic beverage--supposedly to test taste discrimination but in fact to measure ...
