Experimental Report: On Your Marks, Get Set, Remove?
Aim: To investigate which permanent coloured Bic is easiest to remove on lamination paper using Power Force cream cleanser.
Hypothesis: …show more content…
This was unexpected as the 1st time showed 1:00 minute and the 3rd time showed 0:36 seconds. Black took the longest to remove with an average time of 1:32 and 90% removed. The times of each colour varied in ways that during the 1st time, it would either be the longest or shortest compared to the others. The hypothesis observed was about 80% correct; Blue wasn’t the lightest amongst the colours though Black was the darkest and took the longest.
Deciding on the percentage of the efficiency of removing the permanent marker using the cream cleanser was difficult as a comparison between each colour needed to be decided upon. Waiting for each marker to dry after 5 minutes was nerve-racking and keeping the same pressure whilst rubbing the sponge over the spots of permanent marker.
Based on the findings in this experiment, ideas for future experiments would be to observe different variables, ensure accurate timings and using the same amount of solvent for each …show more content…
But I did some research about how I could do these things and ideas started |
| |to come to mind. |
| |I did a little test using a permanent marker on a mirror and used a sponge with a bit of Power Force- an |
| |all-purpose cream cleanser and was pleased to know it would work but I wasn’t 100 sure I was going to use |
| |a mirror in case a particular brand didn’t come off. |
|Saturday 6th August |I began Section 1 and 2 of the assessment task, which required writing an aim, hypothesis, equipment and a|
|2011 |method. |
| |My aim was: “To investigate which type and brand of permanent marker is easiest to remove using Power |
| |Force”.
