• Activity! Creating your own study about
Isopods.
– We will be collecting data periodically over the
next week.
Copyright © 2010 Ryan P. Murphy
• Lab Project with Isopods
– Groups can decide to conduct project about
– Light and Isopod movement
– Moisture and Isopod movement
– Temperature and Isopod movement
Copyright © 2010 Ryan P. Murphy
• We will used mixed Isopods
• – The pillbug (Armadillidium vulgare)
Copyright © 2010 Ryan P. Murphy
Or the Sowbug (Porcellio scaber).

• Pillbugs can roll into a ball. Sowbugs
cannot.

• Observation of Isopods
– Make a detailed sketch of an Isopod,and
describe it’s behaviors.
– Make sketch accurate, count segments, legs,
antennae.
– Make observations about the Isopods behaviors
and how it’s sensing the environment.

• The first two appendages on the male
abdomen are modified as elongated sex
organs.

• On the underside, females have leaf-like
growths at base of some legs.

• Isopod Research Sheet
• Isopod Research Sheet
• Information / Research Available Sheet.
• Information / Research Available Sheet.
• Some general questions.
– How are isopods connected to abiotic factors.
• Moisture, temperature, light, soil, etc.
– What is an isopod?
– Where do isopods live?
– What do they eat?
– What is their reproductive cycle?
– What is their importance (niche) and how do they
impact people?
Copyright © 2010 Ryan P. Murphy
• Gathering background information on
Terrestrial Isopods.
– Use the science name for the internet search.
– Find general knowledge first, then focus.
– Make focus on the pill bug and abiotic factors
– Find a source that is at your ability.
– Record the website address, title, author, year.
Cite sources using APA and Son of Citation
Machine.

• Experiments search for cause and effect
relationships in nature.
• These changing quantities are called
variables.
• Does your grade depend on how much
time you spend on your work?
• Does your grade depend on how much
time you spend on your work?
– The dependent variable depends on other
factors (how much you studied, effort, etc.)

• Dependent: (Observe) What you measure
in the experiment and what is affected
during the experiment.
• Control: (Same) Quantities that a scientist
wants to remain constant so it’s a fair test.
Everything is exactly the same except
for the independent variable.

• A student wants to find out how cigarette smoke
blown into a small greenhouse of plants damages
the plant. The student grows two small plants in
separate clear plastic soda bottles. The students
injects one with cigarette smoke periodically. Both
are watered and given the same light conditions.
The students records the height, number of leaves,
and flowers of both plants everyday for one month.
• Problem? = Does cigarette smoke damage plants?
• Independent Variable = Cigarette Smoke
• Dependent Variable = Height of plants, leaves,
flowers
• Control = Both containers were identical except one
was given cigarette smoke (independent variable).
