Scale of the Universe – Putting the universe into perspective. Link overview chemistrymodels. Middle School Physical Science. Build an Atom - Atomic Structure, Atoms, Atomic Nuclei. Topics Atoms Atomic Structure Isotope Symbols Atomic Nuclei Description Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas! Sample Learning Goals Use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge.Predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass.Use the element name, mass, and charge to determine the number of protons, neutrons, and electrons.Define proton, neutron, electron, atom, and ion.Generate an isotopic symbol for an atom, given the number of protons, neutrons, and electrons.

Show a picture of a pencil point and how the carbon atoms look at the molecular level. Project the image Pencil Zoom. Students should be familiar with the parts of the atom from Chapter 3 but reviewing the main points is probably a good idea.
Ask students questions such as the following: What are the three different tiny particles that make up an atom? Protons, neutrons, and electrons. Which of these is in the center of the atom? Show the simulation Balloons and Static Electricity from the University of Colorado at Boulder’s Physics Education Technology site.
