Overview | Standards and Benchmarks | Description of Chapters | Common Themes | Sample Activities

The PET curriculum consists of six units of
activities that cover introductory physics. The
course is hierarchical, with both topics and skills developed in a structured
progression around
some powerful common themes. A number of
homeworks and activities are specifically designed to meet the curriculum's *Learning
about Learning* content goals.

- Chapter 1:
Interactions and Energy introduces students to all of the common themes
of the course, in particular the themes of interactions between objects and
the energy description of interactions.

- Chapter 2:
Interactions and Forces introduces students to an alternative framework
(that of forces) within which they can explain interactions
they first see in Chapter 1 that involve objects pushing or pulling on one
another.

- Chapter 3: Interactions and Fields
introduces students to the ideas of "fields of influence"
mediating interactions that can occur over a distance, specifically the
magnetic, electric charge and gravitational interactions. The concept of
potential energy is also introduced.

- Chapter 4: Model of Magnetism
concentrates on the nature of science as students develop a model for
magnetism, and then track its evolution among elementary students and
historically, among scientists.

- Chapter 5: Electric Circuit
Interactions introduces students to electric circuit interactions and
how to describe electric circuits in terms of energy and current.

- Chapter 6: Light Interactions introduces students to light interactions. Students examine the interaction of light with mirrors, eyes, transparent objects, white and black objects, and objects of different colors.
