DO NOW 1. What is the main difference between a chemical and physical property? 2. Classify the following as a chemical or physical property: - Phase of matter - Reactivity - Density 3. List three examples of matter. Explain why those things count as matter

HOMEWORK CONTINUE YOUR HOMEWORK FROM LAST NIGHT  will be collected Thursday

HOOK! DIET COKE AND MENTOS! On the Friday before break, this will be your student v. teacher prize. If you win, we do this experiment. If I win, then no

MASTERY CHECK 1. A student makes a chemical reaction happen in an ice compress. What are some signs she might observe that indicate this is a chemical reaction? List at least Classify each of the following changes as either physical or chemical changes. List evidence for your choice. - A hot dog is cooked - Water is boiled - Old ham goes bad in the refrigerator - A rockstar gets a tattoo on his forehead

NOTES Title: Physical and Chemical Changes Prepare our ISNs in the next 20 seconds

Physical Change Key Point #1: A physical change is a type of change that alters the physical properties of a substance but does NOT change the composition Could potentially be reversed! Composition is what a substance is made of

What happens to particles during a physical change? No new substances are formed; particles just move around Cut

What happens to particles during a physical change? No new substances are formed; particles just move around Dissolve

Evidence of Physical Change Evidence: Bending, breaking, smashing, freezing, melting, evaporating, crushing, cutting, tearing, sanding, grinding, mixing, separating, dissolving...

Chemical Change Key Point #2: A chemical change is a change that forms one or more NEW substances Also known as a chemical reaction Cannot be reversed!

What happens to particles during a chemical change? New substances are formed; particles change or rearrange Chemical Reaction New Substance

What happens to particles during a chemical change? New substances are formed; particles change or rearrange Chemical Reaction Particles Rearrange

Evidence of Chemical Change Evidence: Fizzing, burning or combustion, corrosion, production of odor, heat, cold, light, rust, smoke, color change, decomposition, oxidation, rotting, digestion…

STATION TIME! There are 7 stations set up around the room. You will travel as lab groups. You may not work with people who are not in your lab group  You will record observations about the change occurring at your station to decide if they are chemical or physical changes. Some stations might have instructions for you to do something.  Be sure you are recording as we’re going around as you may be called on to provide evidence for your assertion.  You will have 3 minutes at each station.

STATIONS DEBRIEF What evidence did we find at each station to justify our answers?

BRAIN BREAK LASER EYE TAG POISON DART FROG SHARKS ON THE REEF

INDEPENDENT PRACTICE Level 1: If you scored a 10 or below yesterday on the pre-test Level 2: If you scored an 11 or above yesterday on the pre-test
