Flashcard 1: Which option is the best evidence that a material lets some light through: clear image, blurry image, or no image?
Answer: Blurry image. Partial light transmission creates blur in translucent materials.
Flashcard 2: Which type of material usually makes the darkest shadow: transparent, translucent, or opaque?
Answer: Opaque. Blocks all light, creating the strongest shadow.
Flashcard 3: What word describes a material that blocks light so you cannot see through it?
Answer: Opaque. No light passes through, completely blocking vision.
Flashcard 4: Which option best describes clear glass: transparent, translucent, or opaque?
Answer: Transparent. Clear glass allows all light through without scattering.
Flashcard 5: Which option best describes wax paper: transparent, translucent, or opaque?
Answer: Translucent. Wax paper scatters light, creating a blurred view.
Flashcard 6: What word describes a material that lets most light pass through so objects look clear?
Answer: Transparent. Light passes through completely, allowing clear vision.
Flashcard 7: What word describes a material that lets some light through so objects look blurry?
Answer: Translucent. Light passes partially, scattering and blurring the view.
Flashcard 8: Which option is the best evidence that a material lets most light through: clear image, blurry image, or no image?
Answer: Clear image. Complete light transmission shows transparency.
Flashcard 9: Which type of material usually makes a lighter, softer shadow: transparent, translucent, or opaque?
Answer: Translucent. Allows some light through, creating a fainter shadow.
Flashcard 10: What change to the light causes a translucent material to make objects look blurry?
Answer: It scatters the light. Scattered light rays create the blurry appearance.
Flashcard 11: What change to the light happens when it hits a mirror-like surface?
Answer: The light reflects (bounces). Smooth surfaces bounce light back in organized patterns.
Flashcard 12: Which option is the best evidence that a surface reflects light: it makes a clear reflection or it makes a shadow?
Answer: It makes a clear reflection. Reflections show light bouncing off surfaces.
Flashcard 13: Which option best describes cardboard: transparent, translucent, or opaque?
Answer: Opaque. Cardboard blocks all light from passing through.
Flashcard 14: What observation is evidence that a material is transparent when you look at an object behind it?
Answer: The object looks clear and sharp. Transparent materials allow light through without distortion.
Flashcard 15: What observation is evidence that a material is translucent when you look at an object behind it?
Answer: The object looks blurry or fuzzy. Translucent materials scatter light, distorting the image.
Flashcard 16: What observation is evidence that a material is opaque when you look at an object behind it?
Answer: You cannot see the object at all. Opaque materials block all light, hiding objects behind.
Flashcard 17: Which option is the best evidence that a material blocks light: clear image, blurry image, or no image?
Answer: No image. Blocked light means the material is opaque.
Flashcard 18: What is a shadow?
Answer: A dark area made when an object blocks light. Forms when opaque objects prevent light from reaching a surface.
Flashcard 19: Identify the correct claim: If you cannot see a flashlight beam through a material, the material is opaque or transparent?
Answer: Opaque. No light transmission indicates complete blockage.
Flashcard 20: Identify the correct claim: If you see a clear object behind a material, the material is transparent or opaque?
Answer: Transparent. Clear vision proves light passes through completely.
Flashcard 21: What is a translucent material?
Answer: A material that lets some light through, but blurs images. Light scatters as it passes through, making details fuzzy.
Flashcard 22: Which material is most likely opaque: clear glass, thin fabric, or wood?
Answer: Wood. Wood blocks all light from passing through.
Flashcard 23: What is an opaque material?
Answer: A material that blocks light so you cannot see through it. Light cannot pass through, creating shadows.
Flashcard 24: Which word describes a material you can see through clearly: transparent, translucent, or opaque?
Answer: Transparent. Clear view means all light passes through unchanged.
Flashcard 25: Which word describes a material that makes objects look blurry: transparent, translucent, or opaque?
Answer: Translucent. Scattered light creates the blurry effect.
Flashcard 26: Which word describes a material that makes you see nothing behind it: transparent, translucent, or opaque?
Answer: Opaque. No light passes through to show what's behind.
Flashcard 27: Identify the material type if you can read words clearly through it.
Answer: Transparent. Clear text means light passes without scattering.
Flashcard 28: Identify the material type if you can see light, but a face behind it looks blurry.
Answer: Translucent. Blurry images show light scatters through the material.
Flashcard 29: Identify the material type if it makes a dark shadow and you cannot see through it.
Answer: Opaque. Dark shadows form when materials block all light.
Flashcard 30: Which material is most likely transparent: clear glass, wax paper, or cardboard?
Answer: Clear glass. Glass lets light through without changing it.
