Description
This science fair project was done to evaluate the rate of decomposition of bio-degradable plastic in the natural environment. Biodegradable spoons are supposed to decompose with time, but exactly how soon does this process take place? The experiment involved using disposable spoons made from corn starch, wheat and plastic. These spoons were planted in soil.

1. For this science fair project, the independent variable is the type of spoon used ? corn starch based, wheat based and plastic. The dependent variable is the amount of decomposition observed after 30 days. This is determined by using the digital weighing scale to measure the weight of the spoons before and after the 30 days. The constants (control variables) are the type of soil used, the length of time allowed for decomposition, the temperature and humidity. 2. 10 pieces of each of the corn starch-based bio-degradable spoons, wheat-based biodegradable spoons and plastic spoons are marked accordingly, as .....
