-The unit of measurement for temperature is degree.
-Heat doesn't move quickly through an insulator.
-Heat passes quickly through a conductor.
-You can close or open an electric circuit using a switch.
-You cannot see through opaque materials because they block
light.
-Windows look bright and shiny because they reflect light.
-Sound is made when objects vibrate or move back and forth
quickly.
-Electricity goes around and around in a circuit.
-How high or low a sounds is depends on its pitch.
-The loudness of a sound is its volume.
-Particles slow down when matter loses heat.
-Walruses have thick layers of fat that act as an insulator to
keep them warm.
-A spoon in a glass of water will bend the light which is called
refracting.
-Sound and light are both forms of energy. Sound is energy you
can hear. Light is energy you can see.
-The path of a wire from the battery to the bulb to the switch is
a circuit.
-To make a light bulb shine brighter, you can add a dry cell
(battery) to the circuit.
-An insulator will keep matter warm. You may have a cup that is
insulated. It will keep the contents warm.
-The eardrum vibrates inside the eardrum to allow you to hear a
sound.
-Water refracts light or bends it. You may have a difficult time
picking up an item in a pool. The item may seem like it is one places
when it is actually in another.
-Animals can stay warm in the cold weather because their fur
keeps them insulated. Also they change the food they eat into
energy.
-An opaque object will make a shadow when placed in the sun
because it would block the light rays and keep the light from passing
through.
Hypothesize is what you think will happen. To test a
hypothesis that heat moves through a metal cup more quickly than a
plastic cup you could put warm water into both cups. Then place them
in a refrigerator with thermometers , and check them every minute. If
the temperature in the metal cup goes down more quickly than your
plastic cup, then your hypothesis would be correct.
