Entrance Slip: If I have 346.78 kg of gummy bears, and one gummy bear has a mass of 2.3x10^3 mg. How many gummy bears do I have? Give your answer in two significant figures using scientific notation
Entrance Slip Part 2: If I have 300 mm of string. If I want to evenly divide it between three students. How many m of string would each student receive?
Objectives -I can define and differentiate the key terms associated with matter -I can investigate recent scientific discoveries
Introduction to Matter -What is matter? -Is anything not considered matter? -What are the three forms of matter?
Modeling the three phases Liquid Gas Solid
You will assigned a phase of matter: As a group you will have to -Model it -Explain the key details associated with that phase of matter You will have 10 minutes, then you will have to present it
Phases of Matter -What differentiates the different forms of matter? -What are the key characteristics? -How can we tell which is which?
Solid, Liquid, Gas -Shape -Compressibility -Volume
Physical Changes: -Reversible -Alter matter but composition stays the same Physical Properties: -Observable qualities
Chemical Property: -What occurs during a chemical reaction -Help ID unknown substances Chemical Change: -Cannot be undone -When reactants go through a reaction it is the end result
Physical or chemical property -Tastes sour -Boiling point -Reacts with water -length -Toxicity
Chemical or Physical Change -Baking a cake -Freezing ice cream -Burning Carbon -Formation of a snowflake -Spoiling milk
Substance: Can’t physically separate Mixture: Combination Of two substances
Is it heterogeneous or homogeneous Oil and vinegar? Chocolate milk?
What is the difference between substance and a heterogeneous mixture?
What type of matter is this? -Identify the characteristics -Make observations -Develop a claim -Provide evidence to support your claim
