 | Determining the effectiveness of sugar as preservatives for flowers   The objective of this science fair project is to determine the effectiveness of using sugar to preserve and keep the flowers fresh for longer periods of time. The experiment will be carried out using flowers such as the rose, carnations and lilies, and water containing different amounts of sugar | ||

| Examine the effect of plant hormones on radish seeds We are going to investigate the affects of two of those hormones on the growth of radish seeds. This experiment will also investigate the phenomenon of geotropism. A tropism is a growth response of a plant to an environmental influence. Phototropism is the typical growth of plants toward light that most of you have seen. This phenomenon is introduced in your textbook where the discovery of plant | ||

| How does the plant hormone Rootone affect plant growth? The roots with the plant hormone Rootone under the greenhouse effect will grow the fastest because the Rootone is supposed to help roots grow quickly, and the greenhouse effect will keep the plants warm and moist. | ||

beans. What effect does growth hormone supplementation have on irradiated lima
beans. | ||

| Does one bad apple spoil the whole bunch? Does one bad apple spoil the whole bunch? How might one ripening fruit signal others to begin to ripen? What might cause synchrony? Plants use hormones to communicate among tissues. In this experiment, students are introduced to a technique used to evaluate the ripeness of fruit. They design experiments to test hypotheses about the role of hormones in synchronizing fruit ripening in apples. | ||

| Simple experiments to explain the role of phytohormones in plants The plant hormones or phytohormones are involved in all the stages of plant life from pollinisation - inducing the fecondation and the zygotic embryo development, all the way through its development into an adult plant - to flowering, development of the fruit and senecence control.
The same phytohormones not only control the growth and development processes: for that, they are crucially | ||

| Aquatic plants and animals and the acidification of our oceans This experiment was performed to ascertain the effect of aquatic plants on the acidity levels of our oceans. Carbon dioxide levels in our atmosphere have been on the rise mainly due to the burning of fossil fuel and deforestation. The results of this experiment will ascertain whether aquatic plants help to reduce the acidification of our oceans, via the process of photosynthesis. | ||

 | The Usefulness of Plant Growth Enhancers This experiment was conducted to find out the effectiveness of organic fertilizers in improving plant growth. The results of this experiment might help us improve crop yields. | ||

| The relationship between the pH level of soil and plant growth This science fair project was conducted to examine the relationship between the pH level of soil and plant growth. Specifically, what is the ideal pH level at which Kentucky bluegrass grows? Kentucky bluegrass was grown in soils that had different pH levels (6.0, 6.5, 7.0, 7.5 and 8.0). | ||
