Why is aluminum foil used to wrap food but not to insulate hot drinks?
It conducts heat instead of insulating it.
200
A student mixes salt and water until the salt can no longer be seen. How can they separate them?
By evaporation

Put the objects in order from most dense to least dense:
Oil was on top of the water.
The key fell to the bottom of the beaker.
Wood block floated on top of the oil.
Most dense to least dense:
Key, water, oil, wood block
300
Which of the following is NOT a physical property?
a. Magnetism
b. Solubility
c. Flammability
d. Mass
c. Flammability

A student wants to build a circuit. Which materials should they avoid using as wires? Select all that apply.
a. Rubber
b. Copper
c. Wood
d. Plastic
Rubber, wood and plastic. They are all insulators.
300
Which statement is true about solutions?
a. They can only be solids
b. They always looks cloudy
c. They form when one substance dissolves in another
d. They cannot be seperated.
c. They form when one substance dissolves in another
300
Which of the following materials can insulate thermal energy?
a. Rubber ball
b. Copper wire
c. Paper
d. Wooden block
a. Rubber ball
400
Why does a cork float in water but a penny sinks?
Cork is less dense that water so it floats; penny is more dense than water so it sinks.
400
True or False.
All metals are magnetic.
False. Not all metals are magnetic (aluminum and copper are not)
400
Which physical property of matter helps seperate iron fillings from sand?
Magnetism
400
Which of the following is magnetic AND an electrical conductor?
a. Aluminum washer
b. Copper wire
c. Rubber ball
d. Iron nail
d. Iron nail
500
Which tool would BEST measure the volume of an irregular rock?
a. Graduated Cylinder
b. Scale
c. Ruler
d. Milliliters
a. Graduated Cylinder
Measure the volume of water before placing the rock in it and after placing the rock. The difference is the volume of the rock.
500
A piece of cardboard floats in water. Which property of matter helps classify it?
Density. The cardboard is less dense than water so it floats to the top.
500
What would BEST seperate sand and oil?
Water. Sand sinks to the bottom and oil floats to the top.
500
A student mixes 5 mL of salt into a beaker with 500 mL of water. Which of the following statements is true?
a. The mass of the solution is 505 mL.
b. The volume of the solution is 505 mL.
c. The solution can be easily seperated using a sieve.
d. The salt does not dissolve in the water.
b. The volume of the solution is 505 mL.
