The Do Now.Lets review. Lets get ready for the day set up some Cornell Notes!Observation 1: Baking soda & vinegarNaHCO3+CH3COOH NaC2H3O2 + H2O+CO2

Is this chemical or physical change? What is the initial mass?What is the final mass?What happens to the mass of the entire setup?Chemical change

Mass stayed the same

Observation 2: Boiling waterIs this physical or chemical change?What is the initial mass? What is the final mass?What happens to the mass of the entire setup?What type of energy are we adding to the system?

Physical change

Mass stayed the sameWe add thermal energy and see an increase in kinetic energy. We see an energy transfer from the hot plate to the water. Listening in: a songListen to this song by a crazy science teacher carefullyFill in the blanks in the lyrics on the back of your Do Now

Einstein changed up the rules were learning today!The bottom line:The Laws of Conservation of Mass and EnergyLaw of Conservation of MassIn both chemical and physical changes, the total mass of matter stays the same before and after the change. Matter changes, but mass cannot be created or destroyed. Law of Conservation of EnergyEnergy may be converted to another form during a physical or chemical change, but the total amount of energy present before and after a change is the same. Energy cannot be created or destroyed.Element group practice.Complete the practice questions 1-10 on page 94 except 9 and 12-16a on page 95 except 15 of your textbook.
