An Organism for Teaching
this unit, the students explore basic ecology concepts and scientific
processes using spiders as model organisms. They capture spiders,
observe and care for them, and use them to answer their own questions
about spider behavior. Modeling the process of a research scientist,
each team of students designs and conducts their own experiment.
Simultaneously, the class collaborates on joint projects investigating
feeding rates of spiders (by pooling individual feeding data)
and their importance in controlling the numbers of insects (by
conducting a field study on or near school grounds).
The unit includes both teacher and student materials.
The teacher materials include teaching tips, scheduling time lines,
preparation instructions, and resource materials. The student
materials include the lab handouts the students will be using
in each of their experiments. You may select to go to a particular
section by clicking on an underlined title from the list below
or you may choose to follow the flow of the activity by selecting
"Continue to Lesson" at the bottom of this page. At
the end of each section, you will be given a menu from which to choose.
Selecting the choices from left to right will enable you to continue
the natural flow of the lesson.
