Science/Strand III/Content Standard 5/Middle School/Benchmark 1
Benchmark Question: How are parts of an ecosystem
related and how do they interact?
Focus Question: What types of interrelationships
exist among populations in an ecosystem?
Students will write a
journal entry listing relationships they have with other people that are
helpful to them, harmful to them, or competitive. Students will share their
lists with a partner. Students will watch a video about interrelationships
and discuss the main concepts as a class. Students will take a walk to an
area near the school and observe relationships in an ecosystem. With a
partner, students will record their observations. As a class, students will
share and compile their data. Students then will evaluate the relationships
they have observed (helpful, harmful, competitive). The teacher will
introduce key concepts and name the relationships that were identified.
