Class: Physical Science
Periods: B2,3 and W1,3,4
Outcomes: Students will be able to explain how the Law of Conservation of Mass and balancing chemical equations are connected.
Standards: UCP.1-3;,5; A.1,2; B.2,3; G.3
Student Needs:
Assessment Plan: Ticket to Leave: Balance Ba(NO3)2 + K2SO4 BaSO4 + KNO3
Lesson Outline: Review bonding (HNS) > Periodic Video > Biologically speaking, Life is just a set of chemical reactions > Notes over Chapter 21 Sections 1 and 2 > Practice Balancing Equations > Balancing Worksheet and read 21.3 > Ticket to Leace
Review: Draw a molecule consisting of 1 H, 1 N and 1 S
Anticipatory Set/Opening: Periodic video and Life is impossible without chemical reactions
Key Points: Law of Conservation of Mass means the number of each element before a reaction must be the same after a reactions
