This Ecology unit is part of SEPUP’s Issues and Science three-year Middle School program. Each unit of the program incorporates science and engineering concepts and practices with current issues. The Ecology unit focuses on invasive species and their potential harmful effects on native ecosystems and people, and on potential solutions for controlling these species.
Activity 2: Introduced Species
These are good resources which include a comprehensive collection of research publications and education materials on introduced species, as well as searchable databases.
Activity 5: A Suitable Habitat
Capitalize on student interest in L. variegetus at this site which offers laboratory support including videos of locomotion and blood pulsation. Contains information to guide student extensions in experimental design. E-mail contact available. Site is maintained by Charlie Drewes, Ph.D., Iowa State University.
Activity 6: Ups and Downs
You can find out how far zebra mussels have spread each year in the United States on this interactive map produced by the U.S. government.
Includes dynamic maps of for several other aquatic invasive species, including Asian carp.
Activity 8: Eating for Matter and Energy
Student (and teacher) friendly explanation of “the ten percent rule” in ecosystems ecology.
Activity 9: Population Growth
This website will help students learn more about Paramecium and other aquatic protists.
This website has a video (8:32) showing Paramecia and other protozoans living in pond water. There are also links to photos and additional videos.
Activity 11: Cycling of Matter
This site from Cornell University explains the diversity of decomposers.
Activity 14: Effects of an Introduced Species
Two short videos for introducing the Hudson River research study on zebra mussels can be found at this website.
Use this link to access the data on the introduction of the zebra mussel in the Hudson River.
