OUR TEAMLAB 1 WRITE-UPThis problem is an example to be used as a guide for your lab write up. John asks “Why do some of my marigolds grow better in one part of the yard than the other?” Independent and Dependent VariablesIndependent Variables: Water, Soil Type, Sunlight, etc. Dependent Variables: Growth Rate, Final Size, Health, Color, etc. Experimental DesignGroups Experimental Groups: 1)Normal soil, normal water, extended sun exposure 2)Normal soil, normal water, minimized sun exposure 3)Normal soil, normal water, no sun exposure 4)Normal soil, normal water, artificial sun exposure (24 hour sun)
Types Store Bought Plants - Already Flowering Number of subjects per group 5 Groups as seen above Total: 100 plants
Subject SelectionThe subject types selected were to ensure that the pre-grown plants were not the reason for them being healthy, nor that the seedling plants could adapt better to the environment as they attempt to flower.
Sources of Error and BiasNot all plants have the exact same soil around them, rooting may allow for more water exposure, seedlings may be at different points of germination, flowering plants may be older than others, un-predicted weather changes (clouds, rain, etc.)
