DAILY AGENDA 1. Warm-up #39 2.Objective: The student will investigate and understand the following: Identify a physical change and a chemical change. Compare and contrast physical, chemical, and nuclear reactions. Analyze experimental data to determine whether it supports the Law of Conservation of Mass. 3. Endo-Exo lab review 4. Chemical Change Notes 5. Chemical Change Demo 6. Acid Base Worksheet review (Strength of acids/bases) 7. Brain-pop - Endo-Exo reactions 8. Burn Demo 9. Pass out study guide/papers/progress reports

TEST - Jan 21/22 - next week No School - next one TEST - Jan 21/22 - next week

4 Indicators of a Chemical Change: 1. Color Change 2. Temperature Change 3. Precipitate (new substance) Formed 4. Bubbles - Gas Formed

Products on right of chemical equation Reactants on left of chemical equation Endothermic - heat is absorbed - it is cold to the touch Exothermic - heat is released - it is hot to the touch.
