Seed Germination: Preparing for an ExperimentSeventh Grade Science Seed Germination: Preparing for an Experiment
Introduction Purpose Keys to Successful Experiments seed are usefulabundance variety low cost portability
Seed Germination Focus of the experiment Experimental treatmentsEnvironmental factors Terms: radicle, shoot, seedling
Scientific Names Name Must be in Latin Name Must be a binomial2 parts, genus & species
Diagram of the Parts of a SeedDry & pre-soaked seed examinations Label drawing common name family name scientific name
Take-Home Exercise Take home baggies, towels, & seedsRecord names of seed types
Construct an Observation TableUse space on p.6. Observations and Measurements Bring baggies with sprouted seeds back to lab next week Kidney beans, day 2
Summarizing Data Data Statistics Populations vs. Samplesquantitative vs. qualitative variables error, precision, and bias
Graphing - + Correlation: bar graph (frequency within categories)Height (in) Comfort in airline seats - Correlation: bar graph (frequency within categories) Height (in) Weight (lb) + Figure 1: Percent Grade in Classes 20 40 60 80 Band Math Science Art Computers % Grade Classes
Descriptive Statisticsmean population sample median range standard deviation
Presenting Tables Rows & columns Units must be indicated, e.g.,grams (g) centimeter (cm) millimeters (mm)

Introduction Physical factors of the environment Biotic vs. AbioticClimate Soil Stimulants Inhibitors Biotic vs. Abiotic Competition Allelopathy
The pH Scale neutral acidic basic or alkaline
pH Example ACID NEUTRAL BASE
Example Using pH
Fire Exposure Example
Fire Exposure Example CONTROL TREATMENT 1 TREATMENT 2 TREATMENT 3
Supplies and EquipmentProvided: ziploc baggies, paper towels, and seeds Not Provided: inexpensive common household items needed to carry out the experiment
Designing an Experimentproblem hypothesis procedure prediction construct data table
Check it Out (p.7.) I will check your experimental designBegin experiment after you get the “OK” Conduct experiment for ONE WEEK
Writing up Your ExperimentMust Have a Formal Lab Report Write-up which includes Observations table graph Discussion
