Showed off T-shirts to Mrs. Lute's class.

Students filled out wrap-up sheet for Physics Extravaganza.

Handed out paper and asked students to sketch model of atom and then write down what they know about atoms. Hung up pictures and discussed.
Nucleus, protons, neutrons, electrons
Relative masses, size of nucleus vs size of atom
Size of atom - smaller than wavelength of light so can't see it.

Type of element is determined by number of protons in nucleus.
