Atoms • Electrons (-) • Protons (+) • Neutrons (neutral) • Nucleus- the center of the atom. Formed by protons and neutrons.
Insulators and Conductors Insulators Conductors Allow electrons to move easily. Copper and iron are great conductors. You are a great conductor, too! Slow down or stop electrons. Rubber, wood, glass and plastic are great insulators.
Light • Travels in a straight line. • Reflection - occurs when light energy bounces off an object it strikes • Refraction - is the bending of light travelling through different substances with different amounts of thickness.
