Physical Properties
Shiny, dull and metallic describe which of the physical properties?
Lustre
What are the units you use for reporting the volume of a liquid?
Millilitres (mL) or litres (L)
What are the 3 primary states of matter? Which one has particles that move quickly and freely?
Solid, Liquid and Gas
Gas has particles that move quickly and freely.
The first key idea represented in the Particle Model of Matter is: ______________ is made up of small particles.
All matter
What is the first step of the Scientific Method? Which one comes next?
Testable Question and then Hypothesis
Name 7 of the physical properties.
Answers may vary, but may include:
Size, Shape, Colour, State, Texture, Hardness, Lustre, Magnetism, Buoyancy, Compressibility, Density, Mass, Weight, Volume, pH, Solubility, Melting point, Boiling point, Freezing point, etc.
What is freezing point, melting point and boiling point? Use water as an example and tell me it's freezing point, melting point and boiling point.
Accept reasonable answers. Freezing point and melting point are both 0 degrees Celsius and boiling point is 100 degrees Celsius.
Come up to the whiteboard and draw a visual representation of the molecules in a liquid.
Did the teacher say you got it correct?
The second key idea represented in the Particle Model of Matter is: Particles of matter are always __________.
Moving
Which of these is NOT a step of the Scientific Method?
a). Hypothesis
b). Procedure
c). Plagiarism
d). Conclusion
c).
What physical properties are the same for the whiteboard and the smartboard?
Possible answers: Colour, State, Shape, Texture, Magnetism (others they would like to debate?)
What is pH? Give me an example of a real life situation when we would need to determine the pH of something. Where does stomach acid fall on the scale?
Did the teacher agree with your answer?
What state of matter has a definite volume and a definite shape that does not change? What could you do to get it to change shape and take on the shape of it's container?
Solid - heat it up.
DOUBLE JEOPARDY! THIS QUESTION IS WORTH DOUBLE THE POINTS IF ANSWERED CORRECTLY!
The first key idea represented in the Particle Model of Matter is: Particles of matter have ______________ between them and then please do a drawing of this idea for a solid, a liquid and a gas.
spaces
Did the teacher agree with your drawings?
What step of the Scientific Method matches this statement:
I can see that the mint dissolved in 1 minute and 35 seconds, with some fizzing.
Observation
Play I spy with an item in the classroom. Use AT LEAST 7 of the physical properties to describe it. See if a classmate can guess what it was.
Did your teacher say you got it correct?
Explain what density is. Give an example. How is it different from viscosity?
Did the teacher like your answer? Did you answer all the questions?
What three things can you tell me about a liquid and it's molecules?
Some spaces between particles, but not super large. Molecules and move over and around each other, but not free flowing. Possible to compress slightly.
Any others you would like to debate with the teacher?
Attractive forces between particles are _______________ in solids and _______________ in gases.
Strongest; Weakest
DOUBLE JEOPARDY! YOUR TEAM GETS DOUBLE THE POINTS IF YOU ANSWER THIS QUESTION CORRECTLY.
Explain what a fair test is?

DOUBLE JEOPARDY! THIS QUESTION IS WORTH DOUBLE THE POINTS IF ANSWERED CORRECTLY!
Explain the difference between Mass and Weight. What units do we use for Mass?
Mass never changes, it's the amount of matter in an object. Weight can change depending on how much gravity is put upon the object. We use the units: milligrams (mg), grams (g) and kilograms (kg).
Did the teacher like your answer? Did you answer all the questions?
Compare and contrast a solid and a gas. What similarities or differences do they have?
Both are made up of particles because everything is made of particles, but there are three big differences: compressibility, spaces between particles, movement of particles.
What is true about the particles in a substance? Tell me ALL that apply.
a). Particles in all states of matter are arranged close together.
b). The way particles move changes when the substance's thermal energy changes.
c). Particles in all states of matter are constantly moving.
d). Heating a substance can cause a substance to change state.
b)., c)., d).
What do these items represent:
water temperature, the way the mints are dropped into the water, amount of water, type of mints, same size and type of plastic cup, type of water, same kind of clock
What do you call it if you change just one of these items?
Controlled or Constant Variables
Manipulated Variable
