Bringing the Stories Together
Biotic and Abiotic Factors teacher's guide
Convene a final discussion of theScience Bulletinsbringing the stories together through a discussion of how mundane or ordinary aspects of daily life can lead to environmental issues by disrupting ecological function (in this case abiotic factors)
Key Idea: The daily lives of people add abiotic factors to ecosystems, which disrupt many species.
Question: After watching theseBulletinsof the environmental issues that result after changing abiotic factors, give examples of howchanging abiotic factors impact speciesin unforeseeable ways?
- Adding salt kills freshwater ecosystems
- Building concrete buildings absorbs heat and makes the environment hotter
- Adding artificial light at night kills aquatic insects
- Driving and using heating, air conditioning, electronics like cell phones and computers contribute to a rising carbon dioxide levels and temperature.
- Water pollution disrupts large water ecosystems
Question: What are some possible ways to reduce changing abiotic ecosystem factors?
- Using alternatives to salt like CMA
- Constructing buildings with green roofs and planting more trees
- Using non-polarized light, motion sensors, and full cut-off fixtures
- Cleaning up polluted rivers
