Wyoming's Stream Macroinvertebrates

Companion lesson plans for the Biodiversity Institute Wyoming's Streams Macroinvertebrates Guide. Lakes, ponds, streams, rivers and wetlands are full of life.  Many plants and animals live in water and these organisms can be very abundant.  All of these organisms are interesting, but we will focus on aquatic invertebrates in these lesson plan starters.

Pollinator Masks

Show your admiration for pollinating insects by becoming one! Decorate realistically or fancifully with crayons or markers, and cut out the eye holes (for human eyes; large black circles or circles with X). We used pipe cleaners for antennae (insert through the small holes indicated with small black dots) and tied on some elastic. For the bee-fly, fold proboscis in half and tape on just below the antennae.
