Arthropods
Fifth
grade level
Introduction: By nearly any measure, the most successful animals on the planet
are the arthropods. They have conquered land, sea and air, and make up over
three-fourths of all currently known living and fossil organisms, or over one
million species in all. Since many arthropod species remain undocumented or
undiscovered, especially in tropical rain forests, the true number of living
arthropod species is probably in the tens of millions. One recent conservative
estimate puts the number of arthropod species in tropical forests at 6 to 9
million species (Thomas, 1990).
The Challenges:
- Observe:
View the attached websites, navigate through the different links
and become familiar with the use of the internet (see journey).
- Classify:
Using the links below & the inquiry skill of observation,
collect data on the classifications of Arthropods. Compile a list of six different types of
Arthropods, where they can be found (e.g. Crabs can be found in the
saltwater) & a major food source for the arthropod. Please set in up in table form.
