Light and Shadows - Quiz by Kids Academy - Free Printable

Let's go through each of the tasks in your image one by one and solve them based on the concepts of light sources, shadows, transparency, reflection, and light blocking.

---

Task 1: Which picture shows a source of light?

Options:
- Tree
- Sun
- Cat
- Pencil

✔ Correct Answer: Sun

Explanation:
A *source of light* emits light. The sun is a natural light source. Trees, cats, and pencils do not emit light—they reflect it.

---

Task 2: Which is a light source?

Options:
- Candle
- Pen
- Drum
- Rabbit

✔ Correct Answer: Candle

Explanation:
The candle produces its own light when lit. The pen, drum, and rabbit are objects that reflect light but don’t emit it.

---

Task 3: Choose the shadow that would be made by the bird.

Options:
- Shadow of a bird (correct shape)
- Other silhouettes

✔ Correct Answer: The silhouette that matches the bird’s shape

Explanation:
When an object blocks light, it casts a shadow with a shape similar to the object. The correct shadow should match the outline of the bird.

> Look for the silhouette that has wings, a head, and a tail—matching the bird’s profile.

Task 4: Which objects will block light and create a dark shadow?

Options:
- Guitar
- Ball
- Book
- Glass cup

✔ Correct Answer: Guitar, Ball, Book

Explanation:
Opaque objects block light and create dark shadows.
- Guitar, ball, book are solid and opaque → block light → cast shadows.
- Glass cup is transparent → allows light to pass through → does not block light well.

So, guitar, ball, and book are correct.

Task 5: Choose all the light sources in the picture.

Scene: Living room with TV, lamp, window, clock, etc.

✔ Correct Answers:
- TV screen (emits light)
- Lamp (emits light)
- Window (lets sunlight in — but is not a source itself)

Wait — window is not a *source*, it's just a path for light.

But:
- TV → emits light ✔
- Lamp → emits light ✔
- Sun outside window → source, but not directly visible

However, if we're choosing objects in the picture that are light sources, then:
✔ TV and lamp are the two main artificial light sources.

👉 So: TV and lamp

Note: If the sun is visible through the window, it might count, but usually in such tasks, only visible sources like lamps and screens are counted.

✔ Answer: TV and Lamp

Task 6: Choose an object that will let almost all light through.

Options:
- Cucumber
- Dog
- Glass bottle
- Soccer ball

✔ Correct Answer: Glass bottle

Explanation:
Transparent objects allow most light to pass through.
- Glass bottle is transparent → lets light through.
- Cucumber, dog, soccer ball are opaque or translucent → block or scatter light.

So, glass bottle is correct.

Task 7: Choose the object in which you could see your reflection.

Options:
- Flower
- Key
- Dress
- Binoculars

✔ Correct Answer: Binoculars (or possibly the key, depending on surface)

But let's analyze:
- Flower – no reflective surface ✘
- Key – metal, may have slight reflection ✔
- Dress – fabric, not reflective ✘
- Binoculars – lenses are glass, often reflective ✔

But the best answer is likely binoculars because they have glass lenses that can reflect images clearly.

Alternatively, if the key is shiny metal, it might also work.

But binoculars are more likely to show a clear reflection due to their glass surfaces.

✔ Answer: Binoculars

Task 8: Find all the transparent objects.

Options:
- Fishbowl (with fish)
- Red hat
- Light bulb
- Pan (frying pan)

✔ Correct Answers:
- Fishbowl – glass, water → transparent ✔
- Light bulb – glass enclosure → transparent ✔
- Pan – metal, not transparent ✘
- Red hat – fabric, opaque ✘

But wait — light bulb is transparent only if it's off and glassy. When turned on, it emits light, but the glass part is still transparent.

Also, fishbowl is clearly transparent.

✔ Answer: Fishbowl and Light bulb

---
