Which sentence about heat is true?
heat always moves from objects that are cooler to objects that are warmer
heat always moves from objects that are warmer to objects that are cooler
heat sometimes moves from objects that are cooler to objects that are warmer
heat does not usually move
A student conducted an experiment to test whether two objects made of unknown materials are conductors or insulators. The student attached each object to a circuit. The two circuits included identical batteries, bulbs, and wires. Which statement is true?
the experiment is not good because it included more than one kind of material
the experiment is not good because it tested unknown materialsw
the experiment is good because it tested more than one variable
the experiment is good because it tested one variable
A magnetic field forms around an iron nail when you
wrap loops of wire around the nail and pass electricity through the wire
wrap loops of wire around the nail
place the nail near a battery
wrap plastic around the nail and heat the nail and plastic

absorbed light
reflected light
blocked light
refracted light
Which would you use a spring scale to measure?

In an experiment, a student plans to test the magnetism of a copper nail, an iron nail, and a silver ring. Which step should the student include in the experiment?
place each object close to each of the other objects to see ify that attract each other
place a magnet close to each object to see if the magnet repels it
place a magnet close to each object to see if the magnet attracts it
place two magnets close to each other to see what happens
