• Students will be able to explain that living organisms change over time. • Students will be able to define macroinvertebrate and give one or two examples. • Students will use keys and field guides to identify animals in the field.
Essential Questions :
Review and Matching Game – Approximately 20 minutes Macroinvertebrate Madness - Approximately 30 minutes Stream Exploration – At least 35 minutes as part of a field trip Pond Exploration – At least 25 minutes as part of a field trip
Printouts of accompanying material: matching animal drawings (one set per 18 students) and macroinvertebrate water quality key (one for each student).
For stream and pond exploration: small tubs to hold water and creatures, magnifying glasses, small nets, large tweezers, other collecting equipment, and any additional field guides or keys that are handy.
Time will be needed to gather the material and arrange a field trip to a nearby stream (if there isn’t one next to the school).
This activity is meant to follow “Abiotic Adventure.” If not, begin this lesson with the first activity “What’s in a pond?” from the previous lesson “Abiotic Adventure.”
