​Digital Expectations:

• Cameras on for the entire lesson!​

• Participate in the lesson!!

• Mute your microphone when you are not speaking.

• Use the chatbox for questions.

• Minimize distractions during class.

• Follow the Student Code of Conduct.

​Standards:

​S8P1--Obtain, evaluate, and  communicate information about the  structure and properties of matter. (c) plan and carry out investigations to compare chemical and physical properties of matter.

​Essential Questions:

​•What is matter?

•How does matter change  states?

​Learning Targets:

By the end of the lesson I will be able to:

• Define matter.

• List examples of matter.

• Identify the states of matter.

• Describe the difference in particle motion in the states of matter.

​Let's get started!

​You got this!!

​Vocabulary Review

​Solids

• *Solids have definite shape and volume.

• *The particles (atoms) are packed tightly together (fixed position)

• *Little energy, vibrate in place

​Vocabulary Review

​Liquids

• * Liquids have no definite shape but have a definite volume. 

• ​*Atoms loosely packed together and can move around each other. 

• *Medium energy.

​Vocabulary Review

​Gases

• *No definite shape or volume.

• *Gases take the shape of their container.

• *Atoms move freely

• *High Energy

​Vocabulary Review

​Plasma

• *No definite shape or volume

• *Hot ionized (electrically charged) gas

• *Very High Energy

• *Rarely found in nature (sun, lightning, stars)

*Manmade in neon signs

​Vocabulary Review

​Melting

• *A change of state (phase change) from Solid to Liquid

​Vocabulary Review

​Evaporation (vaporization)

• *Change of state (phase change) from LIQUID to GAS

​Vocabulary Review

​Sublimation

• *Change of state from a SOLID to a GAS (Skipping the LIQUID state)

• *Dry Ice and CO2 are examples

​Vocabulary Review

​Deposition

• *Change of state from a GAS directly to a SOLID (Skipping the LIQUID state).

• *Gas to frost on glass in freezing temperatures is an example

​Vocabulary Review

Adding and Removing Energy

• *The addition of energy makes temperatures rise and the atoms and molecules speed up

• ​*The removal of energy makes temperatures lower and the atoms and molecules slow down
