What do we call light produced by a living thing?
Bioluminescence
What type of material usually produces a dark shadow because it blocks light?
An opaque material.
Which planet has a giant storm called the Great Red Spot?
Jupiter
What can the color of a star tell us about the star?
Its temperature
Where does the Moon's shadow fall during a solar eclipse?
On Earth
What happens when light hits a dark-colored object?

What is Ganymede, and what is special about its size?
Ganymede is a moon, and it is larger than Mercury.
Why do we see different constellations during different seasons?
Because Earth moves around the Sun, so we face different parts of space during the year.
Explain the positions of the Sun, Moon, and Earth during a solar eclipse and what happens to the sunlight.
The Moon moves between the Sun and Earth and blocks the Sun’s light, causing the Moon’s shadow to fall on Earth.
EXPLAIN HOW MIRROR LIGTH WORK TOGETHER?
THE LIGHT REFLECT THE FACE AND HID THE MIRROE AND THE IMAGE OF YOUR FACE APPEAR.
Why does a mirror give a clearer reflection than a rough wall?
A mirror has a smooth surface, so reflected light travels in an orderly direction, while a rough wall scatters the reflected light
