Squid
Structure and Function
RI GSEs in Science
K-4 Assessment Targets
Students demonstrate understanding of structure
and function and survival requirements by
4a Identifying and explaining how the physical
structure/characteristic of an organism allows it to survive
and defend itself.
4b Analyzing the structures needed for survival of populations
of plants and animals in a particular habitat/environment.
Identify a question that
leads to inquiry.

Engaging Scenario
The other day, I went to an
Italian restaurant and I
ordered calamari. Calamari is
another name for squid.
I want to know what
structures of the squid I’m
eating. And, what structures
help the squid to survive?

My Focus Question
Class Focus Question


What are a squid’s physical
structures and their functions?
How do they help them survive?
Prediction
1. Draw and label the
structures of a squid you know.
2. Explain the functions of
each structure you know.
