This word means light bounces off a surface.

What is reflect?

100

For you to see an object, this must reach your eye.

What is light from the object?

100

This is the part of the box-model system we changed during the investigation.

What are the light conditions?

100

On the assessment, your diagram should include these two kinds of light paths.

What are reflected and transmitted light?

100

Complete the claim: The strongest one-way mirror effect happens when _____.

What is one side is bright and the other side is dark?

200

This word means light passes through a material

What is transmit?

200

Complete the light path: Sun → tree → glass → _____.

What is the observer’s eye?

200

The one-way mirror effect is usually strongest under these light conditions.

 strongest under these light conditions.What is one side bright and the other side dark?

200

If the trees outside are the most prominent part of the image, this is what you know about the light.

What is more light from the trees is reaching the observer’s eye?

200

Give one piece of evidence from the box-model investigation.

What is the bright side saw a stronger reflection while the darker side could see through more?

300

This word means light energy is taken in by matter

What is absorb?

300

Light from a person passes through glass to your eye. This process is happening.

What is transmission?

300

This usually happens when both sides of the glass have similar amounts of light.

What is the one-way mirror effect gets weaker?

300

This is one change you could make to help the person inside stand out more.

What is increase the light inside or reduce the outside reflection?

300

This explains why the brighter side usually sees a stronger reflection.

What is more light from the brighter side reflects back to the eye?

400

 This word means an object stands out or is easiest to see.

What is prominent?

400

A student draws a light arrow from the eye toward the object. Explain the mistake.

What is light travels toward the eye, not out from it?

400

We recorded Side A and Side B separately for this reason.

What is the two observers may see different things?

400

This science idea explains why one object looks clearer or stands out more than another.

What is prominence depends on how much light reaches the eye?

400

The glass stays the same, but students can see something different. Explain why.

What is the light conditions changed what light reached the eye?

500

 These interacting parts include the light source, objects, glass/material, and observer’s eye.

What is a system?

500

This is why you can see a reflection AND see through glass at the same time.

What is glass can reflect some light and transmit some light?

500

This was the big idea we learned from changing the light in the box model.

What is changing the light changes what reaches the eye and what we see?

500

To explain why one object is seen more than another, students should compare this.

What is how much light from each object reaches the observer’s eye?

500

Answer the unit question: Why do we sometimes see different things when looking at the same object?

What is different light conditions change how much light is reflected or transmitted to each observer’s eye?
