The hypothesis is that peanut oil will have the highest proportion of saturated fat, and when the iodine test is performed, will require the longest time to lose its purple color.

You will clean the test tubes, label them according to the oils used for testing, measure 20ml of each type of oil, and drip 3 drops of iodine into the first test tube. Start the stopwatch immediately and record the time taken for the purple color of the iodine to disappear.

You will need 1 bottle of peanut oil, 1 bottle of canola oil, 1 bottle of corn oil, 1 bottle of soya bean oil, 1 bottle of olive oil, 5 test tubes, 1 test tube stand, 1 eyedropper, 1 bottle of iodine, 1 stopwatch, and 1 measuring cylinder.

The results showed that the iodine and peanut oil mixture took the longest to revert to the original color, while the canola oil took the shortest amount of time. The hypothesis was proven to be true, as peanut oil has the highest saturated fat content and the lowest proportion of unsaturated fat among the 5 types of cooking oil tested.

This science project is interesting because it shows how different types of cooking oil can affect our health. It also demonstrates how the iodine test can be used to measure the amount of saturated fat in different types of oil.

Variations of this experiment could include testing different types of oils like oil palm, coconut oil or sunflower oil. Another variation could be to measure the amount of iodine required for all the unsaturated fat in the oil to react.
