Describe the emergence and level of development of one of the eight psychic principles

I’m working on a writing multi-part question and need an explanation and answer to help me learn.

Referencing Chapter 2 of Montessori, A Modern Approach, comment on the school day depicted, as it was experienced by each of the three children that are followed in the video.  For each of the children, describe the emergence and level of development of one of the eight psychic principles you read about in Chapter 2.  The 8 principles are: 

Law of Work

Law of Independence

Power of Attention

Development of the Will

1. Development of Intelligence
2. Development of Imagination and Creativity
3. Development of Emotional and Spiritual Life
4. Stages of Development
5. Write one paragraph about each child. In describing each child, highlight one of the eight principles listed above and describe how the principle you chose was manifested in that child’s activity.   You can choose a different principle for each child if you like, or focus on the same principle for all three children.
