Isopod Inquiry

Introduction

The student designs an investigation to answer the question "What are the habitat preferences of isopods?" This effort includes background research and observations of isopods. Habitat selection will use joined petri dishes. Other appropriate housing for the test subjects will be provided by the students. Investigation results will be reported using the standard lab report format.

Background Information on Isopods

Literature Research

  1. Classification (Type of Animal: KPCOFGS)
  2. How do they respire? (breathe) lungs, skin, gills, etc.
  3. Food (what do they eat)
  4. Predators (what eats them)
  5. Breeding – sexual or asexual? How many offspring? How often? Eggs?
  6. Habitat – where do they like to live?
  7. Range – extent of geographic area they can be found
  8. Other interesting facts

Microscope Observations

  1. What is their length and width?
  2. How many legs do they have?
  3. How many antenna?
  4. How many eyes?
  5. Do they have three body sections like insects do?
  6. How fast do they run? Explain how you measured this.
  7. When turned upside down how do they flip over?
  8. Describe any interesting behaviors.
  9. Make a detailed drawing of the head (ventral surface).
  10. Make a detailed drawing of the tail (ventral surface).

Lab Report Rubric

Question Question includes both manipulated and responding variables. Question is not "yes or no' and is directly related to the topic of the inquiry.          
Background Includes microscope observations and background research.          
Hypothesis (Prediction) Answers the question, uses "If manipulated variable, then responding variable..."          
The hypothesis includes a cause-effect reason. (i.e. because...).          
Materials A list of the minimum materials needed to perform the procedure.          
Procedure Only one manipulated variable (independent) is identified or implied in the procedure or data table.          
The responding variable (dependent) is identified or implied in the procedure or data table.          
At least two controlled variables (kept the same) must be identified or implied in the procedure or the materials list.  
The procedure states or implies measurements are recorded periodically or gives a data table. The phrase "take measurement" cannot be used to mean record.          
Repeated trials are planned, or implied in a data table, to measure the responding (dependent) variable.  
An experimental control condition should be identified in the procedure.  
Extra Validity measures included - the steps to ensure that the investigator is measuring what they purport to measure.  
The steps of the procedure are logical and detailed enough to repeat the procedure effectively. Diagram of test setup included.          
Data Two tables, one for control and one for experiment. Two double bar graphs for each control and experiment.          
Conclusion A minimal conclusive statement is given.          
The conclusive statement clearly answers the investigative question or explains whether the hypothesis or prediction was correct.          
Start & finish data points (or derived data) are given for the "lowest" condition.  
Start & finish data points (or derived data) are given for the "highest" condition.  
Data is given and an explanation of how the given data supports the conclusion is stated or implied.
