Daily Light and Sound tests for kids
How light travels, shadows, reflection, and how sound is made and travels. Age-appropriate daily practice for ages 7–11.
Sample questions
Here's a taste of what your child will practice. New questions every day on Dailulu.
The speed of light is much ____ than the speed of sound.
Light travels at approximately 300,000 km per second, while sound travels at about 343 metres per second in air.
Why do some objects look shiny when light hits them?
Shiny surfaces reflect light effectively, making those objects appear bright or glossy.
Only bright sounds can be heard by humans.
Humans can hear a range of sounds, including soft and loud sounds, due to the vibrations they make, not just the brightness of the sound.

Questions are tailored to each key stage — the same topic, the right difficulty.
