REVIEW: Darkling Beetles (Tenebrio)
  • An insect.
  • Has 3 body parts (head, thorax, and abdomen).
  • Has 3 sets of legs.
  • Has 2 antenna to sense the environment around them.
  • They are the adult form of mealworms.
  • They go through metamorphosis in their life cycle.
  • They have wings but cannot fly.

REVIEW: Isopods (Armidillidium)
  • Antenna
  • Segmented Body
  • Legs

REVIEW: Isopods (Armidillidium)
  • Isopod is a Greek word
    • Iso = “similar or equal”
    • Pod = “foot”
  • They have segmented bodies and 7 sets of legs.
  • All 14 of their legs function the same.
  • We have Armidillidium (roly-poly) isopods which can roll into a ball.
  • They have a dome shaped, armor like shell.
  • They come in a variety of colors.
testing moisture
Testing Moisture
  • In order to find out the best environment for our isopods and beetles we will need to test two factors:
    • Moisture
    • Light
  • Today we will begin our test of moisture by conducting a two part controlled experiment.
testing moisture materials
Testing Moisture Materials
  • 6 animal runways (which have already been prepared).
  • Dry soil
  • Moist soil
  • Wet soil
  • 3 Dixie cups
  • 9 isopods
  • 9 beetles
testing moisture procedures
Testing Moisture Procedures
  • Set out six of the animals runways (which have already been prepared).
  • In each runway, place one pile of dry soil, one pile of moist soil, and one pile of wet soil.
  • Place 3 isopods in three of the runways (3 isopods per runway).
  • Place 3 beetles in the other three runways (3 beetles per runway).
  • Allow the isopods and beetles 5 minutes to explore.
  • Record where the isopods and beetles end up after 5 minutes.
  • Allow the isopods and beetles time to explorer overnight.
  • We will record the long run results tomorrow at the beginning of class.
vocabulary
Vocabulary
  • Preferred Environment A set of living conditions that an organism appears to choose over other conditions.
review of our objectives
Review of Our Objectives:
  • I can identify and describe terrestrial environments and the effects of environmental factors on organisms.

Review Our Focus Question:

  • How much moisture do isopods and beetles prefer?
