Does Bean Mass Affect Plant Height?
Overview
Objectives/Goals The objective of this experiment was to find out if the mass of a bean would have any effect on the height of its plant. For this experiment three different beans masses would be tested.For example the small beans would weigh 1-2 grams, the medium beans would weigh 3 grams, and the large beans 4-5 grams. Methods/Materials First, the beans would be weighed and seperated into three categories accordng to their masses (small beans 1-2 grams, medium beans 3 grams, and large beans 4-5 grams). Then they are planted in a greenhouse at a 1-inch depth each.Also, they are watered withn a certain amount of water each. The beans are monitored,observed, and the progress is recorded. The materials use were: black beans,scale,soil,greenhouse, ruler,and a logbook. Results In this experiment the small and large beans palnts grew almost the same average height. The medium beans grew the tallest plants. Conclusions/Discussion Based on this experiment and the data recorded the medium size beans grew the tallest plants. This conclusion is based on a sixteen day period.
