||Some seeds are as small as a dust particle
trees are gymnosperms
flowering plants are angiosperms
seeds grow in bag
||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?
||If we make the container bigger then the plant will grow faster…
||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
Get paper towel wet and into container
place the seeds in the container
put under a light
||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.
