Measuring Leaves and Entering Data

Field observations, hypotheses, and organizing data

Head outside to collect leaf samples, practice inductive and deductive reasoning, formulate a testable hypothesis, and organize the resulting data for entry into a spreadsheet.

Introduction and gathering and organizing data

Objectives and goals

• Can you identify inductive or deductive reasoning?
• How do you formulate a question?
• Can you develop a prediction?
• What are hypotheses - Null and Alternate?
• What are dependent and independent variables?
• What is a replicate and how do we sample?
• How do we organize data?
• How do we graph the data we gather?

Schedule:

• Head to the field outside of Swenson and go to pine stand
• Discuss approaches to science and how to make observations
  • Point out the North versus South side of a pine tree and how weather might affect the needled dimensions
• Return to laboratory and measure pine needles
• Organize data
