The lesson presents the difference between an ecosystem and biome, but also introduces students to the connections between these two components of the environment. There are several kinds of biomes, each addressed in other lessons, but they are reviewed here as well. The lesson also introduces students to the various interactions within an ecosystem, including life cycles such as water, carbon, and nitrogen along with related vocabulary. Relevant vocabulary such as individual, population, community, and niche is also defined within the lesson. The lesson may be used in conjunction with lessons related to the environment, biome types or other similar topics.
Sample Classroom Procedure / Teacher Instructions:
- Display a list of various living and non-living things. Ask students: What do the things on the list have in common? Ask them to explain.
- Allow for responses and discussion. Ask students where the things are found.
- Allow for responses and discussion. Ask students how they might interact with each other.
- Allow for responses and discussions. Ask students if they know the difference between an ecosystem and a biome, and how the living/non-living things are related to them.
- Allow for responses and discussion. Introduce Ecosystems and Biomes.
- Distribute Biomes and Ecosystems content pages. Read and review the information with the students. Save the final discussion statement for the lesson closing. Use the additional resources to enhance understanding. (It is highly recommended one or more of the videos are presented to students as a way to “visit” ecosystems and biomes. Teachers may mute the sound and students tell the type of biome, and discuss interactions taking place in an ecosystem.))
- Distribute Activity pages. Read and review the instructions. Pair students. Students are taken outdoors to the possible locations of small ecosystems, such as the sidewalk, in a wooded area, or other location on or near the school. Encourage students to work together.
- Once completed the students will return to the classroom and share their responses, which will vary.
- Distribute Practice page. Check and review the students’ responses.
- Distribute the Homework page. The next day, check and review the students’ responses. Students correct the false statements.
