Grade 1 Science · Light and Sound
Build science skills with five 10-question practice tests covering light sources, materials, shadows, sound, vibration, volume, and hearing safety.
These Grade 1 science practice tests help students observe how light and sound behave. Students identify light sources, compare materials that let light pass through or block it, explain shadows, connect sound with vibration, and practice safe listening.
Complete one 10-question test at a time. Use a flashlight, clear object, book, rubber band, or safe instrument to demonstrate the ideas. Never shine light into someone's eyes or use sounds that are painfully loud.

Correct answer: B
The correct answer is Moving the light source lower.
The position of the light source changes the size and direction of a shadow.
Sound is made when an object vibrates. Drums, strings, voices, and many other sound sources vibrate as they make sound.
A transparent material lets most light pass through so objects on the other side can be seen clearly, such as clear glass.
The page includes five mini tests with 10 questions each, for 50 Grade 1 light and sound questions in total.
