OUR TEAM Name: John Templeton Name: Jessica Schiltz Name: Hannah Horeczko Name: Kristen Okada Name: Arianna Moreno Name: Joslin Jose 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. Experimental Design Groups Control Group: Group receives normal soil found in yard, normal water supply, normal sunlight exposure. 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) Keeping all controls the same except sun exposure time. Could alter different independent variables one or more, but for ease of use, one was chosen. Types Seedlings - From seed Store Bought Plants - Already Flowering Number of subjects per group 20 total plants per group (10 - seedlings and 10 - flowering plants) 5 Groups as seen above Total: 100 plants Subject Selection 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.)
