What’s the Difference?
Matter can change Examples: Freeze, cut, burn, etc. 2 types of changes
1. Physical changes
2. Chemical changes
![Page 6: Physical vs. Chemical Changes Warm-up 2 May 2015 From the “Cooking with Chemistry” activity, describe how did you use phase change to complete the final.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649caf5503460f9497372f/html5/thumbnails/6.jpg)
Physical Property
Characteristic of matter that does not change the substance (using senses)
![Page 7: Physical vs. Chemical Changes Warm-up 2 May 2015 From the “Cooking with Chemistry” activity, describe how did you use phase change to complete the final.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649caf5503460f9497372f/html5/thumbnails/7.jpg)
Physical Changes
Matter changes form WITHOUT becoming something new– You start and end with same thing (see below)
Examples: cutting, freezing, melting, etc.

Chemical Property
Describes matter on its ability to change into new matter– Flammability: ability of substance
to burn– Reactivity: ability of substance to
change into new substance

Chemical Changes
Matter changes, becomes NEW substance– Start and end with different things
Usually irreversible (can’t change back) Examples: burning, rusting, milk going sour

Physical Change vs. Chemical Change
Objective
To correctly identify and differentiate physical change from chemical change.
Question
Are changes (physical and chemical) only present inside the laboratory?How are physical change different from chemical change?
Hypothesis
If physical change does not produce a new product, then I can ….

Discussion/Summary:
• How will you know if an object underwent a chemical or physical change?
• Can changes happen outside of the science classroom or laboratory?

When chemical reactions occur, the connections between atoms must be broken and rearranged. In order to do this, ________________ is involved in all chemical reactions.

There are 2 Types of Reactions Involving Heat
Endothermic Exothermic• Within-Heating
• Endo = Enter
• Therm/ic = Heat
• Outside-Heating
• Exo = Exit• Therm/ic = Heat

There are 2 Types of Reactions Involving Heat (cont.)
Endothermic
Exothermic
• Reactions in which the system absorbs heat from the surrounding.
• Reactions in which the system releases heat to the surrounding.

Products: the resulting solutions in a reaction
Reactants: starting solutions in a reaction
Weekly Reflection/Exit Slip• Name 4 items you
learned in this week’s lesson.
• If Mr. Rivera will teach the lesson again, will you want it done differently?
• If you want it done differently, why and how would you want it?
• If you want it done the same, why?
