LAB 1 WRITE-UP
This 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 Variables
Independent Variables: Water, Soil Type, Sunlight, etc. Dependent Variables: Growth Rate, Final Size, Health, Color, etc.
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)
Store Bought Plants - Already Flowering
Number of subjects per group
5 Groups as seen above
Total: 100 plants
The 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 Bias
Not 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.)
