Essential Common Question(s) (Objective): Why is freezing & melting a physical change and not a chemical change? 56 121 Warm-up: Do you think (hypothesize) that ice melting is going through a physical or chemical change? Explain your reasoning. Questions: 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. Physical properties of objects Standard 5 : Reactions Questions: 57 121 EQ: Why is freezing & melting a physical change and not a chemical change? Notes: A. Physical properties 1. descriptions or characteristics of an object-Matter that can be observed or measured without changing its identity 2. A. shape b. mass c. texture d. volume 3. Describe an object’s physical properties in the classroom It is a blue cylinder Standard 5: Reactions Questions: 57 121 EQ: Why is freezing & melting a physical change and not a chemical change? Notes: B. Chemical properties 1.It is a description on how the substance has the ability to change a. Combustibility (burning) b. color change C. produces bubbles Standard 5: Reactions EQ: Why is freezing & melting a physical change and not a chemical change? Questions: 57 121 Notes: C. Physical Change 1. It does not change its identity. 2. Examples A. Chopping wood B. Tearing paper C. Evaporation, Melting, Freezing and Condensation Ice Liquid water 57 121 Standard 5 : Reactions Questions: Grading: Three questions created at least one level 3 = 3 pts EQ: Why is freezing & melting a physical change and Revision=Underlined/number not a chemical change? ed main ideas (different color of ink). Highlight key Notes: vocabulary. Little notes/ diagrams included.= 2 pts. D. Chemical Change 1. It does change its identity. The properties are different from the original properties. Great! Burnt toast again! 2. Examples The texture does not taste A. Burning paper the same! B. Baking a cake Summary: Answered the EQ question and answered the questions that you created. Have at least one transition word. = 5 pts total. Standard 5: Chemical reactions are processes in which atoms are rearranged into different combinations of molecules.
