Side View (System Setup)
SUN Tree Photographer Glass Window Light OFF Person Inside
Sunny outside; inside room has no lights turned on.
Front View (What the Photographer Sees)
★ Clear Tree Reflection Faint Person Inside
Reflections of outside trees are very bright and visible over the glass.
Word Bank (Use these scientific terms in your responses)
light source (Sun) straight line reflect / reflection (bounces) transmit / transmission (passes through) enters the eye brighter / darker glass window
Scenario: Imagine you are standing outside the glass window next to the photographer. It is the middle of a sunny day. You look into the glass window of the building with no lights on inside. The "front view" is what you see.
1a. Use words or pictures (or a combination) to explain where light travels that causes you to see the trees in this image.
Sentence Frames for 1a:
• Light starts at the light source (Sun) and travels in a straight line to the...
• Next, the light reflects off the trees toward the...
• When the light hits the glass window, it (reflects / transmits) off the surface and enters the...

1b. Use words or pictures (or a combination) to explain where light travels that causes you to see the person in this image.
Sentence Frames for 1b:
• Light from outside (transmits / reflects) through the glass window and illuminates the person...
• Light bounces (reflects) off the person inside toward the...

2 Comparing Visibility of Objects in the Image
Some objects in the front view image stand out much more clearly than other objects.
2a. Identify which object stands out most and least:
⭕ Circle the object that stands out the MOST:
[ ] The Trees (Reflection) [ ] The Person Inside
▢ Put a square around the object that stands out the LEAST:
[ ] The Trees (Reflection) [ ] The Person Inside
2b. Explain in words or pictures why you see one object more than the other object.
Sentence Frames for 2b:
• The (trees / person) stand out more because (more / less) light enters the eye from...
• Outside it is (brighter / darker) than inside, so the reflected light from the trees is...
• Less light comes from the person because the room inside is...

3 Changing the System to Improve Visibility
What could you change in the system to make the person inside stand out more? Include why you think your change will help you to see the person better.
System Change Clues & Word Bank:
Idea 1: Inside Light Turn ON the ceiling lights or a lamp next to the person.
Idea 2: Outside Light Block outside sunlight using an awning, umbrella, or curtain.
Key Vocabulary amount of light, transmits, reaches eye, brighter inside, glare.
Sentence Frames for Question 3:
• One change I would make to the system is to (turn on lights inside / block sunlight outside) because...
• This change would make the inside of the room (brighter / darker) than before.
• Because of this change, more light would reflect off the person and transmit through the glass window into the...
• As a result, the person would stand out more clearly because...
