Reflection
What is throwing back or bouncing off of light, heat and sound without absorbing it (i.e. light bouncing off a mirror)?
100
Transparent
What is a substance that lets light through so objects can be distinctly seen (i.e. most windows)?
100
Triangular Prism
What is something that usually has rectangular sides and triangular ends and is made of glass or quartz; bends light (i.e. sun catchers and diamonds)?
100
Sound
What is energy we can hear that is caused by vibrations? (i.e. sound waves travel like a rock tossed into a calm pond)
100
Echolocation
What is the location of a sound source as it bounces off objects around them?
200
Refraction
What is the bending of light or sound (i.e. a straw bends in a clear glass of water)?
200
Translucent
What is something that allows light through diffusely (ie. some curtains, the blinds in our classroom)?
200
Artificial Light
What is a 'man made' source of light (i.e. light bulb - thank Tesla, not Edison!)
200
Matter
What is something that sound can travel through. It can travel through gases, like air, as well as liquids and solids.
200
Concave Lens
What is when a beam of light passes through it, the light is then spread out (i.e. near-sighted people require this kind of lens in their glasses)?
300
Absorption
What is where something takes in another substance (i.e. black colour of clothing absorbs sunlight)?
300
Opaque
What is not clear, blocking light (i.e. some curtains, window shutters)?
300
Angle of Incidence
What is the angle at which a light ray approaches an object (i.e. we have seasons because of the angle which the sun hits the earth)?
300
Vocal cords
What is the larynx is the 'voice box' in humans? They vibrate when we speak.
300
Convex Lens
What is a magnifying glass (i.e. people that are far sighted need this kind of lens in their glasses)?
400

400
Periscope
What is something used to see around corners (i.e. submarines and some toys)?

What is a shadow portrait? Artists used to trace a person's shadow onto dark paper; your head is opaque when hit by a beam of light)
400
Cochlea
What is the shell-shaped part of the inner ear that is lined with little hairs and liquid? Hairs are joined to nerves and send signals to your brain.
400
Sonar
What is 'sound navigation and ranging'. People use sonar to detect objects under water. Sound waves go through water better than light waves.
500
ROY G BIV COLOURS
What is the colours of the rainbow (i.e. red, orange, yellow, green, blue, indigo, violet)
500
Kaleidoscope
What is an optical toy in a tube that produces symmetrical patterns from bits of coloured glass reflected by mirrors.
500
Mirage
What happens when light hits warm air? Air doesn't always let light beams travel in a straight path. Light hits warm air near the ground and bends it.
500
Decibels
What is the unit measure for sound?
