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
