Light Phenomena
What is our Light and Matter Unit phenomenon?
An object can be a mirror and a window at the same time.
We figured out that the side with the light acts more light a and the side without the light acts more like a .
mirror, window
Which material reflects the most light?
Regular mirror
What object did we use to model the function of the lens in our eyes?
Magnifying glass
What is the term for anything that you can change that might affect the outcome of an experiment?
variable
What does it mean for light to "reflect"?
to bounce off of something
True or False? The box system is a model of the one-way mirror system.
True
Which material transmits the most light?
Glass
Explain the path of light as it enters our eyes and goes to our brain in order for us to see.
Light enters our eyes through the corner, passes through the pupil, is focused by the lens onto the retina, and then converts into an electrical signal that is sent to the brain.
In the following question, do sunflowers grow taller in direct sunlight or partial sunlight?, what is the independent variable?
Amount of sunlight
What does it mean for light to "transmit"?
To pass through something
What claim are we able to make based on our light box investigation when we reverse the side with the light?
When the light was switched to the other side, the mirror side became a window and the window's side became a mirror.
Which material reflected a little bit of light?
One-way mirror
Why does the iris change the size of the pupil?
To control how much light enters the eye depending on brightness.
In the following question, do sunflowers grow taller in direct sunlight or partial sunlight?, what is the dependent variable?
Height of the sunflowers
When light bounces, it , when light bends, it , and when light passes through, it .
reflects, refracts, transmits
How is a one-way mirror made differently than a regular mirror?
A one-way mirror is made by applying a layer of film that is "half-silvered" over glass.
Opaque materials transmit light, while transparent materials , transmit light.
cannot, can
What causes someone to be nearsighted?
The eye being longer than normal from front to back.
In the following question, do sunflowers grow taller in direct sunlight or partial sunlight?, what is the controlled variable?
In order to see any object, what has to happen?
Light has to shine on the object first and then reflect into the eyes.
Why doesn't the music student see the teacher even though light is reflecting off of her, transmitting through the one-way mirror, and into the student's eyes?

Explain the shape of the eye and what a person sees if they are "farsighted"?
The shape of the eye is short and round. If a person is "farsighted" they can see far away without glasses but not close up.
When developing a Driving Question Board, which question is BEST to understanding how a one-way mirror works, Open ended or closed ended and why?
Open ended because a driving question board question should require more than a yes or no answer. They should require a longer explanation and give you space to figure out more things.
