Today, we joined the Primary 7 class to take part in a beeswax filtering experiment. We had to melt the beeswax down and then filter or sieve it to produce a purer and cleaner wax, which in commercial terms, could be used to make candles, furniture polish, lip salve etc.
The variable that we chose to change was the material used to filter the wax. The rest we kept exactly the same. The 4 different filtering material were:
- coffee filter
- kitchen roll
- muslin cloth
- dish cloth
First, we predicted which one would act as the best filter. Most people predicted the coffee filter or kitchen roll because the holes were smaller so less dirt would filter through the material.
Here is a slideshow of our scientific experiment. We hope you enjoy! The results of the experiment are on the last slide, although we also discovered that next time we would use only the cleanest, newest wax and discard the more blackened old wax as this did not melt as well and had to be double filtered.
