Reflection

Before we started on ISS, I thought that ISS would be a very dry subject. But after the process of the investigation, I found that ISS is actually very interesting as we get to choose an investigation of our choice and it is a hands on investigation. From this experience I learnt how to write a logbook. Maintaining a logbook is not easy as it will have to depend on our consistency as we need to update the logbook every lesson to make sure that what we did for the lessons are all recorded down so that when we have to hand it up, all the information will be there and we will not have to do last minute unnecessary work. From this, I learnt not to procrastinate as it will only bring more unwanted trouble. From the literature review, I also understood how to brainstorm for ideas by generating questions and answering them to know more about the topic. In the midst of it, I also found out the proper way of how to quote our sources. From this investigation I learnt that a proper and very through research must be carried out to find out more about the subject and that we must definitely not just jump in to do the experiment without proper background information. Finally, I learnt about constant variables, independent variables, dependent variables, how to plot a graph, write introductions, abstracts, and literature reviews. Although the results that we gathered from our experiment were not accurate, I belief that because of the mistakes made in this experiment, in future we will be more careful, thorough and consistent in our work.

Results

12/8/13 notes

We have already completed the experiment and are now working on the report.

To do list:
- Abstract
- Discussion
- Graph of results
- Poster, video ( Stay back on thursday )

5/8/13 notes

We have finally got the data! Now we need to plot a graph/diagram for the information and see if there is any trend.

2/8/13 Last day of experiment

- Today is the last day of our experiment.
- We took out all the eggs which were soaked in each pH solution
- Then, we put them in beakers according to the 1st or 2nd test and the pH solution.
- We are going to leave them to dry for this morning and next Monday we will go to the lab to weigh the eggs and see the results!

1/8/13 day 4 of experiment

Today, we get to see some results from the eggs soaked in pH 3 and 4. Both of the eggs are cracking and this supports our hypothesis as the cracks are mainly observed in the lower pH solutions. 

Decolourisation can also be seen on the egg in test 2 pH 3.
