Science Flashcards
Reflection
The bouncing of light off an object
Refraction
The bending of light when it moves from one kind of matter to another
Absorption
Stopping light
Shadow
It appears when light is blocked by an opaque object
Thermometer
A tool that measures how hot or cold something is
Insulator
A material in which thermal energy CAN’T move easily
Conductor
A material in which thermal energy CAN move easily
Heat
The movement of thermal energy from one place to another
Energy
The ability to cause change
Thermal Energy
The energy that moves the particles in matter
Prism
A solid object that bends light
White Light
It contains all the color of the spectrum
Specftrum
A band of colors that appear when white light passes through a prism
White
The color we see when all the colors of the spectrum are absorbed
Black
The color we see when all the colors of the spectrum are reflected
Transparent
A material in which all light passes through
Translucent
A material in which SOME light passes through
Opaque
A material in which NO light passes through
Name the colors of the rainbow in order
Red, Orange, Yellow, Green, Blue, Indigo, Violet
Why we see color
Color reflected by objects are the colors we see
Primary Colors
Red, Blue, Green
Why do we see a Rainbow on sunny and rainy days
The raindrops act like a prism and bend the sunlight and we can see all the colors
Name three changes that LIGHT ENERGY can make
Helps plants make food & grow, makes things visible, & solar power
Name three ways that thermal energy can move
Bumping particles (touching), moving liquids and gasses, radiation (sun’s heat)
