Water Breathers

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water. Learners trace the currents in water using diluted food coloring, and closely observe live animals' adaptations for aquatic survival. Learners also consider questions like how does pollution affect water breathers, and how does water breathers' movement affect their environment. Educators can collect live aquatic animals in advance of the activity, or learners can help collect animals as part of a field trip.
