DO NOW: Li-Li-P Take out yesterday’s completed BLUE Video Worksheet & your Einsteins. –Be ready to share your answers from the BACK side of the worksheet.
Add to NB P.60 as today’s IN ? Physical/Chemical Changes BLUE worksheet. Clear off desks of ALL materials EXCEPT the white notes paper for today and a writing utensil.
Today’s Agenda 1.PROPERTIES OF MATTER: Station Rotations –8 stations (7 properties, 1 about chemical v physical properties) –YOU are responsible for filling in the information on your WHITE notes paper—including an illustration for each property! –2-3 minutes per rotation. –At sound of the timer, listen to directions for HOW to rotate to the next station. 2.WHITEBOARDING review 3.Exit Ticket
1 st Rotation SKIP to your next station Stopwatch
2 nd Rotation RESPECTHave a quick convo with your group about what RESPECT means…on the way to your next station.
3 rd Rotation High five everyone you pass on your way to your next station.
4 th rotation Walk like a ZOMBIE to your next station
5 th rotation Sing “the atoms family” 1 st verse on the way to your next station. They’re tiny & they’re teeny Much smaller than a beeny They never can be seeny THE ATOMS FAMILY They’re tiny & they’re teeny Much smaller than a beeny They never can be seeny THE ATOMS FAMILY
6 th rotation Give a compliment to AT LEAST 2 people on your way to the next station.
7 th Rotation Sing & dance to your favorite song on the way to your next and last station.
RETURN TO YOUR SEATS! Walk back to your seat smiling! Add completed notes to your notebook— P. 61. Then clear off desks for whiteboarding!
WHITEBOARDING REVIEW Physical V Chemical Properties
Which property? When something has the ability to burn it is considered…
Physical or Chemical property? Phase or State of Matter
Physical or Chemical change? A rusted iron nail
What is… one sign that a chemical reaction has occurred? Color change Heat given off Gas bubbles produced Light produced
Clear off desks… Put away whiteboards (1 pile center of table) LIDS on the markers—back in the bags! Have out only a pencil for your exit ticket!

What Is The Difference Between A Chemical And Physical Property? PROPERTY: Characteristic of a material that helps to identify or classify matter PHYSICAL PROPERTY: property of matter that can be observed without changing the make-up, or identity, of the matter –Example: Clay is malleable, which means it will bend or flattened when squeezed. Squeezing changes the shape of clay, but does not change what the clay is made of CHEMICAL PROPERTY: charateristics of a substance that describe its tendency to combine with other substances and form new ones –Example: Iron changing to rust by combining with oxygen
Boiling/Condensation Point- Boiling Point is the temperature at which a liquid turns to gas. Condensation Point is the temperature at which a gas turns to a liquid (Physical Property) Water boils at 100 degrees C. Water condenses at 100 degrees C. Gold boils and condenses at 2162 degrees C. Each type of matter has its own unique boiling and condensation point.
DENSITY The amount of matter in a given volume; Mass per unit volume; compactness (Physical Property) Air and cotton have low densities. Granite and steel have high densities. Objects that are less dense can sit on top of objects that are more dense. The billiards ball is less dense than the mercury it is floating on.
Magnetism- The ability to form a magnetic field and attract other metals (Physical Property) ) Nickel, Cobalt and Iron are magnetic, metal elements. The magnetic field can attract or repel (push away). Like poles (north to north) repel each other and opposite poles (north to south) attract one another.
Melting/Freezing point- Melting point is the temperature at which a solid turns to liquid AND freezing point is the Temperature at which a liquid turns to solid. (Physical Property) Water freezes at 0 degrees C and melts at 0 degrees C. Gold freezes and metls at 962 degrees C. Each type of matter has its own unique melting and freezing point.
Solubility- The ability to dissolve in another substance—how well the substance dissolves. (Physical Property) Solids dissolve in liquids. Gasses dissolve in liquids. Solids dissolve in solids. Gasses dissolve in gasses. Can you figure out what is dissolving in what in each picture?
Conductivity- The ability to transfer thermal energy (heat) from one area to another. (Physical Property) Metals transfer heat quickly – that is why you get cold sitting on a bleacher. The heat from your body is transferred to the bleacher. Hot pads stop the flow of heat. They are not good thermal conductors.
Acidity - the ability of a compound to produce hydrogen atoms in water. Acidic items taste sour and react with metals to produce hydrogen gas (Chemical Property ) The ph scale is used to tell how acidic or basic a substance is. Simply put, the pH of a solution if the measure of the amount of hydrogen atoms in a solution on a scale from 0-14. A solution with a pH of less that 7 is considered basic. Some solutions that are very acidic are lemon juice, cola, and stomach acid.
