(...) is made up of (...)
Matter, atoms
the sum of potential and kinetic energy, machines use this energy to perform tasks
Mechanical Energy
Draw and label the Atom
Two forms of light
photons and waves
tiny, very fast back and forth movements; first step in process of sound
vibration
Flow of electrons and protons
electricity
involves the movement of electrons and protons, used to power lightbulbs and ovens
electrical energy
two types of electrical circuits
complete (electricity will flow because components work) and incomplete (electricity will not flow because components do not work)
Light waves have peaks and valleys, and the distance between two peaks is called
wavelengths
any substance through which sound waves can travel
medium
paths for transmitting electric currents or moving electricity
electric circuits
stored in nucleus of an atom, released by splitting or joining nuclei
nuclear energy
many moving electrons
electric current
objects that don't let light through, instead they reflect and absorb it
opaque
picks up sound waves, such as ears
receiver
6 components of a circuit
battery, bulb, buzzer, wires, motor, switch
stored energy and moving energy
potential and kinetic
when all colors of light travel together they create
white light
Objects that allow light to pass through
transparent
the ear changes sound waves into (...) that travel to the brain
signals
a (...) is a material that allows electricity to flow through it, a (...) is a material that does not allow electricity to flow through it
conductor, insulator
stored in bonds between atoms and molecules, it is found in food and can be converted into heat energy by the body
chemical energy
Scientists use (...), like triangular glass pieces, to separate white light into individual colors. This colorful display is known a a (...)
prisms, spectrum
objects that let some light through but aren't entirely see through
translucent
vibration, or wave, that travels through matter (solid, liquid or gas) and can be heard
sound
