Extra Extension
activity:
• You are a scientist who is studying
various ecosystems.
• As part of your research, you need to
identify as many BIOTIC and ABIOTIC
factors as possible.
• Using the magazines provided, glue,
scissors, and construction paper, make a
collage of at least 5 abiotic and 5 biotic
factors.
