* Remove dirt and roots. * Measure each phenotype’s mass and record the data. * Cut up 1g of each phenotype (measure with the scales) and place into a test tube filled with 25mL of ethanol. * Boil the contents of the test tubes in a beaker filled with 250mL of water till the biological matter has become a liquid. – Add boiling chips to the beaker * Pour each phenotype into the spectrometer’s measuring prisms * Record the data presented by the light absorption meter

Data Collection: In what form will you record your results in your logbook? Table / Graph / Diagram? What measurements will be made ? Are there any special safety precautions or ethical issue to consider?
Using all three methods of presenting data, graphs, tables and diagrams I will determine the height of each individual plant and the weight relative to each Phenotype within each species.

Introduction
What contributing factors create the best conditions for plant growth and how have these conditions manipulated growth rate? The aim of the experiment was to investigate the effect of genetic lineage (inheritance patterns) on peas and barley when the variables,
