Define the term ‘prototype’-
A prototype is a model of a product which is used for testing before a manufacturing run is ordered. Many companies run through several prototypes when developing a new product, as they learn more about the manufacturing process, how people will use it, and how it can be broken.
So simply a prototype is a modal of a actual product.

1. What preliminary research did you conduct to commence your project? Things that I researched to commence my project were-

1.) Explain the purpose of using ‘youtube’ as a source of digital media advertising? Purpose of that is because youtube has become quite famous in people, as well you can add and play videos.
2.) Discuss how collaborative media sites such as youtube, myspace and bebo have changed the current boundaries of media such as news, advertising ect.2). Many people prefer watching Youtube or going to sites like myspce or bebo . So obviously, people will view different kinds of advertisements rather than the news.

In our today’s lesson we conducted the practical “common indicators”. This practical was about what happens when an indicator mixes with other acids, base and water. So an indicator like methyl orange mixing with sodium hydroxide would most likely turn yellow. Most of the results are shown in our textbook Science Focus 3, pages 61 and 62. Another successful practical…J
And so far as a group I think we are working very well, we are sharing the work around and we are communicating well so hopefully we can carry on like this therefore receive good marks for our project…J

In our today’s lesson we conducted the practical “displacement”. We put a piece of zinc into a copper sulphate solution. We waited for a while (5 min) and then saw what was happening, the piece of zinc changed its colour from silver to black colour. It was another successful practical, which was carried out by our class…J

In our today’s lesson we conducted an experiment that was about different metals reacting with different acids. We were given 3 different acids-hydrochloric acid, sulphuric acid and acetic and 4 other metals-magnesium, zinc, aluminium and iron.
We only managed to test all 4 different metals in the hydrochloric acid and sulphuric acid and yet there wasn’t any reaction that we were hoping for. We hoped that it will make a popping sound but it didn’t, in fact magnesium and aluminium were the only two metals that had a reaction, they started forming bubbles as soon as the light up matchstick was held over the test tube. We did not get to finish the rest of the experiment and the class ran out of matches. So this was our first experiment which didn’t really work out…L

In our today’s lesson we firstly took down some notes on Naming Ionic Compounds and then under stood the whole system on how it works, Everyone In the class really paid attention to this, as miss said that this will certainly help us out in our future and we will be needing this information for further chemistry…Later in the lesson we got to see our results for the experiment we did with iron nail in different conditions. These are the results that we got -

In our today’s lesson we had a Test on a practical report. We got giving a paragraph on a experiment which was carried out by a student it was based on how far you could jump with your feet together compared with jumping with your feet apart. We had to write paragraphs on Hypothesis, Equipment, Result, Conclusion, Question, Variables and Discussion. In this report they had given us the names of the person the foot size and also the distance they jumped. This whole report test took the whole period. Luckily in this test I managed to get 22 out off 26, thanks miss…J

The second practical that we did in our class was on Combustion meaning “the process of burning”. We had a little limewater in one testube and the other test tube with sulphur. The testube with sulphur was held on top of the Bunsen burner via the help of tongs and both were connected with small hollow tube. What we saw then was that the limewater transformed into a black colour and it had started forming bubbles.

In today’s lesson we did 2 practicals. First one was done to see what would happen when you burn magnesium strip over the Bunsen burner. So we got a little piece of magnesium strip and held it over the Bunsen burner via the help of tongs. It then reacted with the heat that was giving off by light and heat energy so it then caused very bright flame and few fire sparks. This material is found in Fireworks to make the bright colours and other fancy things such as sparks.
