Light, Shadows & Reflection — Drills · Grade 6 Science
Chapter: Electricity, Magnetism & LightWhat these drills covers
By the end of Light, Shadows & Reflection you should be able to:
- I can use straight-line travel to explain the size and sharpness of a shadow.
- I can apply the law of reflection to predict where a reflected ray goes.
- I can explain why a mirror shows an image and a matt wall does not.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: normal, reflection, evidence, system boundary, uncertainty.
Problem 1
- A visible object must generate its own light.
- Reflection angles are defined from the surface rather than the normal.
- normal: A line perpendicular to a surface at the point being considered.
- A sample with missing measurements has proved those values are zero.
Answer and explanation
normal: A line perpendicular to a surface at the point being considered.
A line perpendicular to a surface at the point being considered.
Problem 2
- Repeating any method makes every causal claim true.
- A visible object must generate its own light.
- Reflection angles are defined from the surface rather than the normal.
- reflection: Light being redirected from a surface.
Answer and explanation
reflection: Light being redirected from a surface.
Light being redirected from a surface.
Problem 3
Answer and explanation
The reflected angle measured from the same normal, not the angle from the mirror surface.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 4
Answer and explanation
Its surface scatters reflected light toward many directions rather than preserving one sharp organized image.
