Lesson Plan – Animal Breathing – 3rd year of elementary school

O respiratory system It is responsible for gas exchange between the animal's body and the external environment. These gas exchanges can be through the gills, the skin or the lungs.

Animals that breathe through gills are usually aquatic, this type of breathing is called gill.

Animals that breathe through their skin are amphibians, this breathing is called cutaneous.

On the other hand, animals that exchange gases through the lungs, like us humans, have lung breathing.

We prepared a lesson plan on types of breathing in animals so that you can apply it to classes of students in the 3rd year of elementary school, however, this class can be easily adapted to other classes.

Be sure to also check out our activity suggestion on the subject that is attached, along with the lesson plan, in PDF at the end of the text.

Lesson Plan – Animal Breathing

THEME: animal breathing

SUGGESTED TIME: 2 classes

GOALS:

• Understand the different ways of performing gas exchange in animals.
• Relate the type of respiration to the animal's habitat.

MATERIAL REQUIRED:

• Images of animals, on cards or projected with a computer and data show.
• Images of the different respiratory systems of animals.
• Activity with respiratory systems for coloring (suggestion attached to the lesson plan PDF).

DEVELOPMENT:

Class 1

1. Begin the lesson by asking students about how fish breathe. They are expected to answer that they breathe in water. Then ask why humans can't breathe normally underwater.
2. Introduce students to the importance of oxygen to animals, spark a discussion about how animals in different environments get oxygen.
3. Show the respiratory system of fish, explain the use of gills and how they get oxygen.
4. Do the same with the respiratory system of amphibians that have skin breathing.
5. Show the human respiratory system and explain how it works. Detail each organ and its function.
6. Ask everyone to stand up and place one hand on their belly and the other below their nostrils. Inhale and exhale together, count aloud to pace everyone's breathing in three beats.

Class 2

1. Distribute the activity with the drawings about the respiratory systems of animals.
2. Recall with them the difference between the three systems: branchial, epithelial and pulmonary.
3. Ask them to color and briefly describe how the human respiratory system works and describe its main organs.

ASSESSMENT:

The evaluation must be carried out with the participation of students in class 1 and with the correction of the activity in class 2.
