subatomic particles: the pieces of matter that make-up an atom

The main subatomic particles are: protons, neutrons and electrons.


 * Protons have a positive charge, contribute significantly to the mass of the atom and are located in the nucleus.


 * Neutrons no charge, contribute significantly to the mass of the atom and are located in the nucleus.


 * Electrons are negatively charged, do not contribute significantly to the mass of the atom and are located outside of the nucleus.

Create a keynote or movie that could be used to instruct upper elementary students about subatomic particles. At minimum your presentation should include descriptions of each particle, your answers to the following questions and the table found below. Your presentation should be between 10 and 20 minutes.
 * Assignment**

All atoms of an element have similar physical and chemical properties. In addition to their properties, elements are identified by the number of protons their atoms contain. Why do you think the number of protons can be used to identify an element?

Create a table to organize the following information about the three sub-atomic particles: charge mass location effect of loss or addition to an atom
