Document Summary
The results must be reproducible (to within experimental error) and, as more and more experiments are conducted, a pattern should begin to emerge, from which a comparison to the current theory can be made. If a magnet is drawn through the mixture, the iron filings will be attracted to the magnet and the wood will be left behind. When the glass-sucrose mixture is mixed with water, the sucrose will dissolve, whereas the glass will not. The water can then be boiled off to produce pure sucrose. Olive oil will float to the top of a container and can be separated from water, which is more dense. It would be best to use something with a narrow opening that has the ability to drain off the water layer at the bottom (i. e. , buret). The gold flakes will settle to the bottom if the mixture is left undisturbed. The water then can be decanted (i. e. , carefully poured off).
