  4. 59 Bill Nye Fluids • 10 facts

  5. Standard 5: Chemical reactions are processes in which atoms are rearranged into different combinations of molecules. Essential Common Question(s) (Objective): Why is freezing & melting a physical change and not a chemical change?

  6. 56 121 Warm-up: Do you think (hypothesize) that ice melting is going through a physical or chemical change? Explain your reasoning. Questions: Physical properties of objects 1.Describe two objects at your home using physical properties. List at least five physical properties each. 2. Would shaping clay be a physical or chemical change? Explain.

  7. Standard 5 : Reactions 57 121 EQ: Why is freezing & melting a physical change and not a chemical change? Questions: Notes: Physical properties A. • descriptions or characteristics of an object-Matter that can be observed or measured without changing its identity • A. shape b. mass c. texture d. volume 3. Describe an object’s physical properties in the classroom It is a blue cylinder

  8. Standard 5: Reactions 57 121 EQ: Why is freezing & melting a physical change and not a chemical change? Questions: Notes: B. 1.It is a description on how the substance has the ability to change • Combustibility (burning) • color change C. produces bubbles Chemical properties

  9. Standard 5: Reactions 57 121 EQ: Why is freezing & melting a physical change and not a chemical change? Questions: Notes: C. • It does not change its identity. • Examples A. Chopping wood B. Tearing paper C. Evaporation, Melting, Freezing and Condensation Physical Change Ice Liquid water

  10. 57 Standard 5 : Reactions 121 EQ: Why is freezing & melting a physical change and not a chemical change? Revision=Underlined/numbered main ideas (different color of ink). Highlight key vocabulary. Little notes/ diagrams included.= 2 pts. Questions: Notes: D. 1. It does change its identity. The properties are different from the original properties. 2. Examples A. Burning paper B. Baking a cake Chemical Change Grading: Three questions created at least one level 3 = 3 pts Great! Burnt toast again! The texture does not taste the same! Summary: Answered the EQ question and answered the questions that you created. Have at least one transition word. = 5 pts total.
