A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc2.
B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion.
C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy.
D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields.
E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.

Virtual Manipulatives
This virtual manipulative will allow the students to understand that the electric field is the region where the force on one charge is caused by the presence of another charge. The students will recognize the equipotential lines that exist between the charged regions.
Some of the sample learning goals can be:
- Determine the variables that affect how charged bodies interact.
- Predict how charged bodies will interact.
- Describe the strength and direction of the electric field around a charged body.
Type: Virtual Manipulative
The students will rub a balloon on a sweater and see how charges are exchanged between the two objects. With these changes they will see their interactions.

This virtual manipulative will help the learners understand Coulomb's law which is the fundamental principle of electrostatics. It is the force of attraction or repulsion between two charged particles which is directly proportional to the product of the charges and inversely proportional to the distance between them.

This virtual manipulative demonstrates the electrostatic interaction between a charged balloon and a wall. Students may play with the slider of "Charges on the balloon" to change the type and amount of the charges on the balloon. The simulation also has the option of seeing a microscopic model which helps in understanding the phenomenon. After adjusting the charge press PLAY to observe the interaction.
