Graphing, Mapping, Ordering
•Mathematics• underlies almost every biological experiment performed
• even before any analysis of results
• Follow rules of making graphs• Review on pg 7 & 8 of Lab Manual
Certain plot shapes = infer causal mechanisms
• Scatter plots • Ordinary scientific
activity
• Bell shape curve• Associated with random
samples
• Exponential curve graphs• Concave upward curve
as with early stages of bacterial growth
• Carrying capacity graph• Carrying capacity in the
environment
• Sine-wave-like curve • Biological rhythm
Ordering
• Also important• Sequencing of a protein
• Sequencing of genes along a chromosome
• Pecking order in a chicken coop
• Trophic levels in a food chain
Mapping
• Very important in Biology
• Localization of organelles to world mapping of biodiversity
Problem Solving
• Connection between• Game playing strategies• Problem solving
strategies
• Concept maps• Punnett squares• Pedigrees• Tables• Anything to help determine a pattern
Analysis
• BLAST• Basic Local Alignment
Search Tool• Basic information tool to
help design cladograms
• INVESTIGATION 3 in lab manual
Hypothesis Testing
• Statistical analysis • Helps to distinguish between multiple working hypotheses
• Helps to propose and investigate all possibilities or a particular phenomenon
• Helps to design experiments to eliminate all but one competing hypotheses
Modeling
• From Words to Equations to Graphs• Simple models help biologists explore complex systems• Models can be used to explore various possibilities• Models can lead to the development of conceptual
frameworks• Models can make accurate predictions• Models can generate explanations
The FOXRAB Game
• Construction of a model game
• Writing out assumptions as word equations
• Abstracting the word equations into arithmetic equations
• Generating a spreadsheet
• Graphic model of the game played over time
Miniposters
• Title• Abstract• Introduction with primary question, background context, and hypothesis
• Methodology• Results, including graphs, tables, charts, and statistical analysis
• Conclusions, or interpretations of results based on hypothesis
• Literature cited
