Details:
|
The student performed tests on Kentucky Bluegrass seeds to find out if hydrogen peroxide would be the most effective means of loosening the seed coat. This is a complete project, with graphs, sources and a step by step procedure. Because of this student's experiments, she was forced to reject her original hypothesis.
