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
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
- 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.

homeworks in PET, see the Table of Contents (PDF).
