Why the Human Body: Building Blocks and Nutrition is Important:

This domain covers a number of topics regarding the human body. This domain first covers concepts regarding cells and how cells form the building blocks of life on Earth. Students are then taught how collections of cells form tissues, and tissues form organs, and finally how organs work within the various body systems. In addition, students are taught about Anton van Leeuwenhoek and his work with the microscope and his discovery of the tiny one-celled bacteria.

Students will then hear about the digestive and excretory systems. They will learn the fundamental parts and functions of these two body systems. The narrator of these read-alouds is a nutritionist named Nick Nutri, who reinforces basic facts that students will be learning.

The remainder of this domain focuses on the importance of good nutrition and how to make good choices in order to eat a well-balanced diet. Students will be taught five keys to good health—eat well, exercise, sleep, keep clean, and have regular checkups.
