Aquatic Insects: Water Quality Index & Diversity Index

Do golf courses affect the water organisms in nearby streams and ponds? Small groups collect samples of water upstream and downstream from a golf course and analyze the macroinvertebrates found and the stream index values of...

How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local...

What kind of organisms are living in the stream? After an explanation on how to use a dichotomous key, groups of three to four use the keys to identify macroinvertebrates from a local freshwater stream. Using the the concept of...

Insects are the focus of an activity that looks deep into the anatomy and metamorphosis of everyday bugs. Two worksheets reinforce knowledge obtained through a teacher-guided grand conversation and insect observation.

Why read about it when you can watch it happen? Bird cams make it possible for learners to experience the life cycle of a bird in real time! An engaging set of lessons provides activities to connect their learning to bird cam...

High schoolers identify the different types of water and explain in what proportions they exist on Earth. They identify and correctly label the parts of the water cycle and how these parts interact with each other. Students identify...

Some insects breathe air yet live underwater. The video explains how they carry air with them and the scientific principles behind this ability. It focuses on beetles and surface tension as the concept of nature's scuba divers becomes...

What would the world be like with no insects? Ponder this question using a research-based STEM unit that encourages scholars to investigate insects from both a beneficial and hazardous perspective. They learn about insect behaviors,...

Field study groups collect samples of stream water and identify the macroinvertebrates found. Using their data, they calculate a water quality index to rate the health of the stream. They graph their data and discuss the value of a water...

Students identify the adaptive forces in the life cycle of plants, animals, and humans, isolate and identify the role that change and adaptation play in extreme environments and research and write a short term paper using MLA citations.
