Description | ||
| This science fair project was conducted to find out how the environment affects the decaying process in wood. The following tests were carried out by first immersing the wood in either rainwater, acid water (which simulates acid rain), sea water or soil | ||

| 1. For this science fair project, the independent variable is the environment in which the pieces of wood are kept for 2 weeks – whether in rain water, acid water, salt water or wet soil. The dependent variable is the average strength of the wood after 2 weeks. This is determined by applying weight to the planks and noting the breaking point of the wood. The constants (control variables) are the size of the wooden planks used, the length of time they are exposed to the environment, and the type of wood used. 2. The experiment is begun by ..... | ||
