Explore Some seeds are as small as a dust particle trees are gymnosperms flowering plants are angiosperms seeds grow in bag
Research Question How will the size of the container affect the growth rate of the plant? how will the amount of times we water the plant affect the growth? How will the amount of light affect how fast it grows?
Predictions If we make the container bigger then the plant will grow faster…
Experimental Design Independent Variable = type of container Dependent Variable = how fast the seed is growing Variables to Control = how much water we put on the towel. kind of seed. amount of light being put on the seed Materials: plastic bag petri dish light sources seeds Procedure: Gather supplies Get paper towel wet and into container place the seeds in the container put under a light collect data
Conclusion The reason we think this happened: I think this happened because of the amount of space the plant had. In the dish, it was more of a competitive environment, due to the fact that roots were overlapping and when space ran out it could not push the walls out like the ones in the bag could. Also, the largest in the dish would always get the most water. The bag was more air-tight so that heat would get in but not out, and the bag would stay damp because the water never got through the opening.
