Section 1
Animals Use Special Body Parts to Move
Animals move in different ways using specialized structures. Wolves run on strong legs, snakes slither using their entire bodies, snails slide on slime trails, and birds fly with wings.
In this Grade 3 lesson from Science: A Closer Look, students explore how animals use structures such as lungs, gills, legs, wings, and fins to move, find food, and stay safe in their environments. Through hands-on observation of a snail, learners compare and contrast animal structures across different species and investigate how animals respond to their environments. The lesson builds foundational life science vocabulary and scientific inquiry skills aligned with Chapter 1: A Look at Living Things.
Section 1
Animals Use Special Body Parts to Move
Animals move in different ways using specialized structures. Wolves run on strong legs, snakes slither using their entire bodies, snails slide on slime trails, and birds fly with wings.
Section 2
Animals Gather Food and Water With Specialized Structures
Animals use different body parts to obtain necessities. Lions lap water with rough tongues, birds scoop with beaks, and elephants use trunks. These same structures often help with gathering food too.
Section 3
Animals Breathe Through Different Structures
Animals get oxygen in various ways. Many breathe using lungs to take oxygen from air, while fish use gills to extract oxygen from water. Some creatures like worms absorb oxygen directly through their skin.
Section 4
Animals Find Shelter or Use Protective Structures
To stay safe, animals either find shelter or have protective body parts. Groundhogs dig holes, birds build nests, porcupines have sharp quills, and snails use hard shells to protect themselves.
