Examples of great science projects include those that pose questions, such as whether tea stains the teeth or if aspirin helps plants grow. Other examples are those that teach how to do something, such as making a solar oven or a lemon battery.
To conduct a science project about whether aspirin helps plants grow, start with two pots, potting soil and seeds. Plant both pots with the soil and the same amount of seeds. Label one "aspirin water" and the other "plain water."
Dissolve two aspirins in hot or boiling water, and allow to cool. Keep this solution in a bottle labeled "aspirin water." Place the pots in a sunny spot. Water the experiment pot with the aspirin water. Use the same amount of plain water for the control pot. Keep this experiment going for a designated amount of time, keeping track of the results.
Successful science fair projects usually have display boards. Typically these consist of tri-fold boards. In the center board goes the title of the project, in this case the question of whether aspirin water affects plant growth.
On the lefthand side should go the abstract, hypothesis and background research. In the center of the board go the materials used, the procedure and a brief overview of the results. On the righthand side include the conclusion and future directions of the project.
