Study Hall: Work quietly at your seat (homework, study, draw, read) NO TALKING. NO EXCEPTIONS. SIT IN ASSIGNED SEATS.
Announcements • Class Representative: Olivia Coachman! Congrats to all the Candidates; it was a very close election!
1st Block - Announcements • Blue Medical Forms • Returned forms? • Curriculum Night • TONIGHT……Wednesday, September 25 • 5:00 -7:00 pm
3rd Block Only • Quiz results…. • Tracking…..
Warm Up-Physical or Chemical Change? • Write each statement then label it either P (physical) or C (chemical) __________cooking an egg __________melting an ice cube __________rusting of an iron pan __________melting gold __________burning wood __________crumpling a sheet of paper __________breaking a bottle __________mixing acid and base __________digesting food in your stomach __________freezing __________condensation
Take Notes • Shape is a characteristic property of matter: an object will retain all of its characteristic properties regardless of its shape. • both clear and colorless, have a boiling point at 100ºC, can dissolve table salt, etc.
Take notes • Some factors that can change the characteristic properties of matter are heat, temperature, and pressure
Key Ideas: • Matter can be divided into: • physical properties • chemical properties • In your notebook, draw a table with 2 columns • Label left column Physical • Label right column Chemical Physical Chemical
Brain Pop Video • “Property Changes”
Notes on Physical Properties: • Physical Properties: • can be measured and observed • no chemical change to the substance • Includes State of Matter changes (solid, liquid, gas)
Physical Changes • Examples: • color • Odor • density • Solubility • melting point • boiling point
Physical Changes Question: Wood cut in half Physical or chemical change?
Chemical Changes • New substances are formed! • “Tablets reacting in solution” • Nail rusting outside
Chemical Properties • Includes properties such as acidity, basicity, combustibility, and reactivity.
3rd Block Discovery Ed video • “Chemical and Physical Properties of Matter”
Properties of Matter Foldable • Fold your paper “Hot dog Style” • You are going to write vocabulary terms on one side of your foldable as shown by the example
Vocabulary Terms • Mass • Volume • Density • Melting Point • Boiling Point • Solubility • Solute • Solvent • Temperature
Vocabulary Definitions • Write these definitions on your foldable • Solvent = in a solution, it’s the matter that dissolves the solute • Solubility= the amount of a solute that can dissolve in a solvent • Solute = in a solution, it’s the matter that gets dissolved into a solvent
Solubility • Remember Solubility = an ability of a substance to dissolve • A solute’s solubility depends on : • type of solvent used • the temperature of both the solute and solvent • particle size • The most common solvent = water known as the “universal solvent”
Solute vs. Solvent? • To put it in simple words:When we add sugar to water, it will dissolve. In this process: • Solute? • the sugar • Solvent? • the water • Solution? • Sugar water
Experiment Time! • Solubility and Temperature Experiment • Add this entry into your notebook • Groups will be assigned • Each member will have 1 set of directions • Read all directions and write all information in your notebook • Remember the cups (red, yellow, green)
Discovery Ed video • “Solubility”
Vocabulary Definitions • Write these definitions on your foldable • Mass (review word) = the amount of atoms in matter, determines how heavy or light matter is • Volume (review word) = the amount of space that matter takes up, how big or small something is
Vocabulary Definitions • Write these definitions on your foldable • Density = how “crowded” the atoms are in matter • Melting Point = the temperature at which a solid will melt into a liquid
Vocabulary Definitions • Write these definitions on your foldable • Boiling Point = the temperature at which a liquid will boil into a gas
Vocabulary Definitions • Write these definitions on your foldable • Temperature = the amount of heat present in a substance or object
Add Illustrations to your foldable • Beside each definition, draw a picture that helps you visualize each of our new vocabulary terms Melting point =
