Plant Lab

Biology 11: Plant Lab

Test #1: Compare germination rate of Kholarabi seeds at three different temperatures:

Room temp, heat mat temp, fridge temp

Design a Scientific experiment

Research Questions that need to be answered prior to designing experiment – what is kohlrabi (subspecies: superschmeltz), Scientific classification (Kingdom to species), Nutritional value, growth parameters (light, soil type, temp, humidity, size of plant, length of time to harvest), phototropism, anatomy of a seed, cotyledon significance and how many does kohlrabi have, method used to sprout seeds.

Hypothesis – define and state for your experiment. What is your best guess about what will happen

Materials – identification on all items and materials used

Procedure – Define the following – dependent and independent variables, control variables, groups and individuals

Data – what variables are you measuring, how often: time to germinate, rate of growth of cotyledon

Discussion – State whether your hypothesis was correct, partially correct, or incorrect. Re-approach and suggest a better hypothesis if new evidence came out of your experiment. E.g. heated mat may be the fastest germination rates but does it bring its own problems of fungus growth. Discuss any difficulties and suggest methods to overcome.

Conclusion – one or two sentences summarizing your findings.
