Stream Investigations

(Recommended for 4th & 5th Grades)
Combine research with personal field observations!  Students assess the life-sustaining components of the stream community, collect macroinvertebrate speciments, and trace the flow of energy.  An afternoon TeachCam session, allows students to examine a variety of aquatic organisms, and identify the special features which help them to survive.

Meets PDE Academic Standards: See list below!

What the teachers are saying:
Thank you for a day of learning in the real world!  It is obvious that the leaders are knowledgeableand have a love for children!  Hopefully their passion to care for our environment will be something students will pick up as foremost today.

What the students are saying:
I loved how you did the activity with us before we went in the stream.  It opened up a world of understanding to me.  I love how you are using your time and making an effort to save the environment.  It shows.  It was cool how we got to take a closer look at our world through the microscope.  I understand how a mayfly nymph breathes through his abdomen because of that.  Please keep doing this for many more years to come - it's worth it.
