pretty cool huh?so now that i've done everything, i shall put up my method in "prose and passive past tense".
Method:
A table (as shown below in table 1) was drawn up so that the results could be recorded on. A metal drainer was placed on a dish and 250 grams of sand was measured and placed in the drainer. 250 millilitres of oil was then measured out and poured onto the sand. The oil was left to filter for 60 seconds and the amount of oil that resided in the dish was then subtracted from 250 millilitres to find out how much oil was actually absorbed by the sand. The experiment was then repeated the next day with oil and potting mix and oil and healthy soil from the garden. The day after that, the experiment was repeated except with petrol instead of oil and the day after that, it was repeated with engine coolant instead of oil. A week of analysis was then left in between and the entire experiment was repeated again for reliable results.
BTW: Table 1 is non- existent at the moment...
