Allelopathy: Do Some Plants Inhibit Growth of Others Science Project
Investigate the allelopathic effects of certain plants on the growth of others. Conduct experiments to observe the relationships between different species!
In this science fair project, you will collect water samples from local sources and test them for contaminants such as nitrates, phosphates, and pH levels. By comparing your results with local water safety standards, you will assess the quality of your local water supply and its potential impacts on health and the environment.

If we analyze the water samples, then we will find varying levels of contaminants that may exceed safety standards.
