英文版的化学实验报告 英文版的化学实验报告 Introduction: Chemical experiments are an essential part of scientific research and education. They provide valuable insights into various chemical reactions and help us understand the properties and behavior of different substances. In this report, we will discuss the process and findings of a chemical experiment conducted to investigate the reaction between hydrochloric acid and sodium hydroxide. Experimental Procedure: 1. Materials: The materials used in the experiment included hydrochloric acid (HCl), sodium hydroxide (NaOH), distilled water, a burette, a conical flask, a pH meter, and a magnetic stirrer. 2. Preparation: A solution of hydrochloric acid was prepared by diluting a given volume of concentrated hydrochloric acid with distilled water. Similarly, a sodium hydroxide solution was prepared by dissolving a specific amount of sodium hydroxide pellets in distilled water. 3. Setup: The burette was filled with the sodium hydroxide solution, and the conical flask was placed on the magnetic stirrer. The pH meter was calibrated according to the manufacturer's instructions. 4. Titration: The hydrochloric acid solution was slowly added to the conical flask while stirring continuously. The pH meter was used to monitor the change in pH during the titration process. The addition of hydrochloric acid was stopped when
Title The title for the lab report may be provided by your lecturer. If not, you will need to make up your title. It should be brief, informative, and interesting. It is not usually a sentence. You should aim to provide just enough information in the title to avoid it being overly general. The key is to be concise and meaningful. Check with your lecturer if you need to include a title page and ensure all the relevant information is supplied. This will include your name, student number, date of the experime nt, the demonstrator’s name and the group you belong to. Introduction The introduction should be clear and concise. It should tell the reader what to expect in the report. An introduction generally includes the following elements: ? Problem – State the issue investigated by the experiment. ?Background –Briefly summarise previous research on the topic and narrow the scope of the study. ? Objectives – State the aim of the experiment and state the methods used. ? Hypothesis – If this is not already given, you must formulate this in unambiguous terms. The introduction is written in the past tense following the scientific style of writing. Materials and methods This section should contain a clear enough explanation of how you conducted the experiment so that someone wishing to replicate the procedure may be able to do so. Here you should describe the experimental design, the treatments and the apparatus you used. You should follow the rules for the conventional descriptions of chemicals. The standard practice is not to use trade names for chemicals. Instead you should use the generic or chemical names. Standard apparatus should be described in proper technical terms. Also, you should describe the procedures and methods of measurement you used. At the end of this section you should provide details of how you analysed the data. If this involved lengthy statistical calculations, these should be attached as an appendix. Results and discussion This section should be organised in a systematic way such that you first present the results and then discuss them. To report on results you should describe what happened. This is perhaps the most important section of your report because it is where you report the data upon which your conclusions are based. Accuracy, clarity of expression and systematic presentation of the data (e.g., use of tables, graphs, figures, diagrams, etc.) are key factors here. Take note that tables and figures do not simply repeat information given in the text –they are meant to summarise, amplify, or complement it. You should report first the results that bear directly on the title of your lab report. Any other interesting findings should follow this. If the experiment had more than one hypothesis, you may want to organise your results in a way that reflects this. A key
Experiment Report Name:刘岚清Major:Psychology No: 2015214236 Report time:2017.03.11 The Stroop Effect: A Demonstration of Interference in the Reaction of Tasks. 1Abstract The Stroop effect is a demonstration of interference in the reaction time (RT) of a task first named by John Ridley Stroop in 1935. The most popular explanation is processing speed which suggests there is a lag in the brain's ability to recognize the color of the word since the brain reads words faster than it recognizes colors. In this experiment, thirty-three undergraduates majored in psychology in Central China Normal University participated in. They’re asked to name color or read words for name of a color printed in a different color. The experiment is Latin square designed. The result prove the prediction that the RTs of reading color are longer than reading words, and RTs when names of colors in a different color from the color named are longer than other conditions. 2 Introduction 2.1 Experiment objective In psychology, the Stroop effect is a demonstration of interference in the reaction time (RT) of a task. When the name of a color (e.g., "blue", "green", or "red") is printed in a color that is not denoted by the name (e.g., the word "red" printed in blue ink instead of red ink), naming the color of the word takes longer and is more prone to errors than when the color of the ink matches the name of the color. For example, people are likely to read color of the word “green” as green. (John Ridley Stroop, 1935) There are several theories used to explain the Stroop effect and are commonly known as “race models”. For example, processing speed suggests there is a lag in the brain's ability to recognize the color of the word since the brain reads words faster than it recognizes colors. Lamers found that word processing is significantly faster than color processing. In a Stroop test, if the task is to report the color, the word information arrives at the decision-making stage before the color information which presents processing confusion. Conversely, if the task is to report the word, because color information lags after word information, a decision can be made ahead of the conflicting information (Lamers, 2010). The aim of this experiment is to show that the contradiction between the color and literal meaning can interfere the reaction time. 2.2 Experiment content This experiment is mixed designed, and the independent variable is different tests and groups with different orders

英文实验报告格式范文 英文实验报告格式范文 Title: The Effect of Temperature on Enzyme Activity Abstract: The purpose of this experiment was to determine how temperature affects the activity of the enzyme amylase. Three different temperatures were tested: 10°C, 25°C, and 45°C. The results showed that the rate of reaction increased as the temperature increased up to 45°C. However, at temperatures above 45°C, the rate of reaction began to decrease due to denaturation of the enzyme. The optimal temperature for amylase activity was found to be 45°C. These findings have important implications for the use of enzymes in industrial processes. Introduction: Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process. They are essential for life and are used in a wide range of industrial processes. Enzyme activity is affected by a number of factors, including temperature, pH, and substrate concentration. Temperature is one of the most important factors affecting enzyme activity. Enzymes have an optimal temperature at which they work most efficiently. At temperatures above or below this

英文版实验报告 英文版实验报告 Introduction: In this report, we present the findings and analysis from a recent experiment conducted to investigate the effects of caffeine on cognitive performance. Caffeine, a widely consumed psychoactive substance, is known to have stimulant effects on the central nervous system. The objective of this experiment was to examine whether caffeine could enhance cognitive abilities such as attention, memory, and reaction time. Methodology: Participants: A total of 50 healthy adult volunteers aged between 18 and 30 years were recruited for the study. They were randomly assigned to two groups: the experimental group (received caffeine) and the control group (received a placebo). Procedure: Participants arrived at the laboratory after an overnight fast and were instructed to abstain from consuming any caffeinated beverages or food for at least 12 hours prior to the experiment. They were then given either a capsule containing 200mg of caffeine or a placebo capsule. The experimenters, as well as the participants, were blinded to the group assignments. Cognitive tests: After a 30-minute absorption period, participants completed a battery of cognitive tests. These included a sustained attention task, a memory recall task, and a reaction time test. The tests were designed to measure
