PLANT GROWTH EXPERIMENT Numerous environmental variables influence plant growth. Three students each planted a seedling of the same genetic variety in the same type of container with equal amounts of soil from the same source. Their goal was to maximize their seedling’s growth by manipulating environmental conditions. Their data are shown below. Plant Seedling Mass (grams) Day 1 Day 30

The five major variables of project management are essential in pretty much every project. Time which would is the amount of time required to complete the project. Typically it is broken down into the time required to complete the components of the project. This is then broken down into the time required to complete each task contributing to the completion of the project. Then there is cost which will typically be determined by the consultant or contractors hourly rate multiplied by an estimated
