2.1 assignment- Undertake titration and colorimetry to determine the concentration of solutions. 2.2 assignment- Undertake calorimetry to study cooling curves. 2.3 assignment- Undertake chromatographic techniques to identify components in mixtures. 2.4 assignment- Review personal development of scientific skills for laboratory work.

Applied Science unit 5 M1 To differentiate between: a)Those questions that science is currently addressing b)Those questions that science cannot yet answer c)Those questions which science will never be able to answer (M1)

This is my assignment for Unit 2A on Titration. I have achieved DISTINCTION on this assignment including other assignments as well. This assignment contains both theory and practical work including my calculations, pictures of my graph, and conclusions. SIDENOTE: These assignments should only be used as a guide! These assignments are uploaded for you to see what a distinction-level assignment looks like, not to be copied.

this is the assignment for applied science unit 4

P1-Describe the development of a scientific theory, highlighting the process involved.

First, I described using the practical circuit investigation and a range of measurement devices such as an oscilloscope, multimeters, data loggers, and the principle of operation of the following types of the transducer. then I went further on to explain and describe how analog and digital meters can be used as measurement devices in circuits. then I wrote down my method and my results and drew a graph and ended with a conclusion.

I first described the different electrical circuits such as ammeter, light emitting diode, and others. then next I described the electrical formulae and relationships such as Kirchhoff's first law and second law. furthermore, I did some equations with the different electrical circuits such as power and charge and other electrical parts of the circuit. In all the experiments I did I recorded down the filament bulb I recorded the volts, the current, the volts, and the current in addition to this ...

summarising your literature review to produce an introduction to your report in the third person and using scientific terminology. I did the three sets of results and I rounded it up to a second decimal number and did a standard deviation. Then I analyzed the results and I did a conclusion. Then I compared the conclusion with two valid and cited and relevant sources. Furthermore, this i did an evaluation of my assignment and critically evaluate the skills which you have developed. In addition to...

I chose the method from the different methods from different assignments. I wrote down the apparatus which I needed. I did a risk assessment which included the hazard, risk, and control. in addition to this when I was doing the experiments there were milestones that I reached and I took note of them and incorporated it into my assignment. then I did a contingency plan in case there was no apparatus or the experiment could not have happened. I described how I could improve my plan and finally I c...

Research and summarise 3 pieces of literature about your topic. The aims which I set before I did the experiment and if I achieved them. then I wrote the hypothesis, the null hypothesis, the independent and dependent variable, and finally the control variable. Then I wrote the different types of methods that I wanted to use and I researched the pros and cons of the methods. furthermore to this, I justified the method I proposed and the limitation of the method which I proposed lastly, I wrote th...
