300
Which of the containers can use a strainer to separate?
Container 3
Pebbles are like gravel and too big for the openings.
300
What 2 properties of salt that change when dissolved in water?
The texture and the size.

True or False: All metals are magnetic
False
400
The ability to keep heat or electricity from passing through matter.
Insulator
400
Which material is the best conductor of heat?
Material 3
The best conductor sent energy through it and into the air. It has the lowest temperature after 15 minutes.
400
What are the 4 steps to separate a container of glass beads, plastic beads, and steel beads into 3 piles?
(plastic beads are less dense than water)
1) Magnet to separate the steel beads
2) Add water to the container to make the plastic beads float
3) Skim/Scoop the plastic beads from the water.
4) Tea strainer to separate the water from the glass beads
400
What is the best way to describe what happens to matter when it dissolves in water?
The matter breaks into smaller pieces until it is too small to see.
400
Are there any physical changes when you make lemonade?
If yes, what change?
The sugar dissolves.
400
Adding heat to change a liquid to a gas
Evaporation
400
Why does a soda can that was taken out of a refrigerator develop condensation on the outside of the can?
Because the temperature of the air is warmer than the temperature inside the can.
500
To break down into small pieces too small to be seen.
Dissolve
500
Whether something sinks or floats in water
Relative Density
500
How do you classify a 2 metal bolts with 2 properties of matter: 1 is copper and 1 is iron.
Copper: Conductor not magnetic
Iron: Conductor is magnetic
500
What are the 4 steps to separate a mixture of salt, iron filings, and sand into 3 separate piles?
1) Use a magnet to separate the iron from the salt and sand
2) Pour the salt and sand into water
3) Pour the water and sand through a coffee filter and funnel
4) Evaporate the water
500
What is the biggest and most important difference between a mixture and a solution.
One ingredient goes through a physical change to make a solution.
500
Which container had at least 1 ingredient have a physical change when mixed?
Container 2
Salt and changed size and texture.
500
Removing heat to change a gas to a liquid.
Condensation
500
When you make a solution of salt and water, is the mass of the salt conserved within the solution?
Yes. If you add a specific amount of solute (salt) the solution conserves (keeps) the mass.
example: 100 g of water + 10 g salt - 110 g solution
