NY Harbor Populations Investigation
In this activity, students sort their invertebrates into difference categories based on close observations.
- Make close observations
- Develop a categorization system
- Modify their system based on feedback and effectiveness
Materials and Resources
- a set of small invertebrates in a small tank with an aerator
- several Petri dishes
- white paper (taped to desk so animals in petri dish can be seen more easily)
- hand lenses
- sieves or screens
Before you get started
Tips for Teachers
- Remind students to transfer the organisms extremely gently!
- Note: This activity is a rich source of student questions about small arthropods. Be sure to record your students’ questions and add them to your running list. You’ll need that list for the students to propose large-scale studies in the upcoming lesson, Propose a NY Harbor Population Study.
- Each group gets their same small tank with invertebrates and their supplies.
- Each group also has access to...
- extra brackish water
- a sieve or screen
- BOP Species ID Cards and Food Web Cards (they are not required to use them at this time, but as they raise relevant questions, consider directing them toward these resources)
