Timing: |
1 Day |
Rationale/Goal:
· Question: What organisms perform cellular respiration?
· Question: Why do our lungs have so many alveoli?
Overview:
This is another reading in a series of adventures that Peppi and Bollo go on in their journey through the human body. In this journey, Peppi and Bollo demonstrate why there are so many alveoli in the lungs by relating it to the villi that were discussed during the section on human digestion. They will also follow the path of oxygen and carbon dioxide through the blood stream.

Learning
Objectives [cognitive,
academic, language, socio-cultural] |
Assessment
Criteria |
|
Students will describe the path of blood through the human body. |
After visiting the alveoli, red blood cells carry oxygen to the heart and then through the body, and then go back to the heart before revisiting the lungs and alveoli. |
|
Students can define cellular respiration, including the products and ingredients. |
Cellular respiration occurs in all living things, and is carried out in the cells. Carbon dioxide and heat are waste products of cellular respiration. Cellular respiration provides us with energy. |
|
Students will have a basic understanding of photosynthesis. |
Plants carry out photosynthesis, which provides the oxygen we need for cellular respiration |

The
output of one system can become the input of another system. |
Give
an example of how output of matter or energy from a system can become input
for another system (e.g., household waste goes to a landfill).*a |

Multicellular
organisms have specialized cells that perform different functions.
These cells join together to form tissues that give organs their
structure and enable the organs to perform specialized functions within
organ systems. |
Relate
the structure of a specialized cell (e.g., nerve and muscle cells) to the function
that the cell performs. Explain
the relationship between tissues that make up individual
organs and the functions the organ performs (e.g., valves in the heart
control blood flow, air sacs in the lungs maximize surface area for transfer
of gases). Describe
the components and functions of the digestive,
circulatory, and respiratory systems in humans and how these systems
interact. |
