Physical Properties (4.6A)
A student describes three mystery samples:
Sample 1 flows and takes the shape of its container.
Sample 2 keeps its own definite shape and volume.
Sample 3 expands to fill all available space.
What are liquid (Sample 1), solid (Sample 2), and gas (Sample 3)?
Which type of solution is formed when sugar is stirred into water until it dissolves?
What is a Solid + Liquid Solution?
What scientific rule states that matter cannot be created or destroyed when creating a mixture?
What is the Law of Conservation of Matter?
What science tool is used to measure the mass of solid objects before and after mixing?
What is a Triple Beam Balance (or Digital Scale)?
An iron nail is attracted to a magnet, but an aluminum soda can is not. What physical property differentiates these two metals?
What is Magnetism?
Which type of solution is formed when vinegar is added to water?
What is a Liquid + Liquid Solution?
You mix 50 grams of soil with 100 grams of water. What is the total mass of the resulting mud mixture?
What is 150 grams?
What science tool is used to measure the volume of liquids before creating a solution?
What is a Graduated Cylinder?
If a plastic bead stays at the top of a cup of water, but a marble drops to the bottom, what physical property explains why the bead stays at the top?
What is Relative Density (or floating because it is less dense than water)?
Classify these two mixtures as either Liquid + Liquid Solution or Solid + Liquid Solution: Food coloring + water and Salt + water.
What is Liquid + Liquid Solution (Food coloring + water) and Solid + Liquid Solution (Salt + water)?
When vegetable oil is poured into water, the oil floats on top without dissolving. Does the total mass of the oil and water change after they are combined?
What is No, the mass stays exactly the same?
What optical tool would a student use to examine the tiny, individual grains in a mixture up close?
What is a Hand Lens (or Magnifying Glass)?
True or False: A larger object will always have more mass than a smaller object.
What is False (a large balloon can have less mass than a small steel marble)?
What is the main difference between a basic mixture (like sand and water) and a solution (like salt and water)?
What is in a solution, one substance evenly dissolves into the other?
Why doesn't water "disappear" when it soaks into dirt to form a wet soil mixture?
What is the water spreads between the dirt particles, so its mass is still included in the mixture?
What tool is used to measure the temperature of a liquid mixture in degrees Celsius?
What is a Thermometer?
List all five physical properties that scientists test to describe and classify matter.
What are Temperature, Mass, Magnetism, Relative Density, and Physical State?
If rubbing alcohol is mixed evenly into water, what type of mixture is created?
What is a Liquid + Liquid Solution?
A student seals 30g of water and 30g of salt inside a baggie and shakes it until the salt dissolves. What will the scale read when the baggie is weighed after the salt dissolves?
What is 60 grams (plus the weight of the baggie)?
Name the two tools you would need to measure the mass and volume of a liquid mixture to compare its properties before and after mixing.
What are a Balance/Scale (for mass) and a Graduated Cylinder (for volume)?
