Warm Up 1) How can Mr. Baden make second semester better than first semester? 2) What are 5 things you know about electricity?

Electricity Protons have a Positive Charge Neutrons have a neutral (or zero) charge Electrons have a negative charge Protons and Neutrons are IN the Nucleus Electrons and Protons have the same strength charge The amount of charge on one proton/electron is 1.6 * 10-19 Coulombs

Electricity The Coulomb 'C' is the unit for electric charge Oppositely charged particles attract, like charged particles repel

Electricty When charges move it is the electrons which actually move. Conductors allow charge to move Metals, ceramics Insulators do NOT allow charges to move Plastics, wood, Glass, rubber

Worksheet

Cool Down 1) Which particle has a positive charge 2) Which particle has a negative charge 3) Which particle is NOT found in the nucleus?

Electricity Charge distributions

Extra vocab words Subatomic – smaller than an atom Static – not moving, staying the same
