- Each atom has a charged sub-structure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.
- The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.
- Do Now– Get out your science notebook and add to the Table of Contents- “Protons, Neutrons, Electrons p.70” (Left Side); Head page 70 properly with “Protons, Neutrons, & Electrons-Simulation & Demonstration-4/17/17.”
- Simulation– Balloons & Static Electricity PhET- Visualize what happens to electrons when a charged balloon is brought to a wall with the simulation. Set up page 70 with title. Cut & tape diagram to page 70. Write captions beneath each diagram explaining what happened between the balloon and the wall in the simulation.
- Demonstration– Balloon and Stream of Water video- On page 70, record your observations of what happened when the charged balloon was held near a stream of water and explain why it happens.
