Science expands students biological understanding of life by
focusing on the characteristics of living things, the diversity of
life, and how organisms and populations change over time in terms
of biological adaptation and genetics. This understanding includes
the relationship of structures to their functions and life cycles,
interrelationships of matter and energy in living organisms, and
the interactions of living organisms with their environment.
Concept 1: Characteristics of Organisms Understand that basic
structures in plants and animals serve a function. PO 1. Identify
animal structures that serve different functions 13The headThe
first part of an insect is its head. The head of an insect is used
for eating food, and understanding its environment.
3ThoraxThe thorax is the middle part of an insects body. It is
used to balance and support 3 sets of legs. Sometimes the insect
has wings. Wings are also located on the thorax.
4AbdomenThe abdomen of an insect is the third body part. The
abdomen is used for digestion and reproduction.
5Six legsAll insects have 3 pairs of legs. This makes 6 legs
total. Legs help insects crawl, swim, dig and grasp. Notice the two
pointed objects coming out of the insects head. These are not legs,
these are antennae.
