Simple Circuits: Paths, Switches & Energy — Drills · Grade 6 Science
Chapter: Electricity, Magnetism & LightWhat these drills covers
By the end of Simple Circuits: Paths, Switches & Energy you should be able to:
- I can explain why the current is the same before and after a bulb in a series circuit.
- I can predict the brightness of bulbs wired in series and in parallel.
- I can explain what voltage measures and why mains voltage is dangerous.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: circuit, parallel branch, evidence, system boundary, uncertainty.
Problem 1
- circuit: A connected path supporting charge flow and energy transfer under stated conditions.
- The lamp consumes the charge, leaving none in the return path.
- A picture of a closed circuit proves a real device is safe and functioning.
- A sample with missing measurements has proved those values are zero.
Answer and explanation
circuit: A connected path supporting charge flow and energy transfer under stated conditions.
A connected path supporting charge flow and energy transfer under stated conditions.
Problem 2
- A picture of a closed circuit proves a real device is safe and functioning.
- parallel branch: A separate conducting route between shared connection points in a circuit.
- The lamp consumes the charge, leaving none in the return path.
- Repeating any method makes every causal claim true.
Answer and explanation
parallel branch: A separate conducting route between shared connection points in a circuit.
A separate conducting route between shared connection points in a circuit.
Problem 3
Answer and explanation
No. Its location matters: a branch switch and a switch in the shared path affect different routes.
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
Actual connections, component ratings, source condition, and the intended switch positions. Paper evidence establishes the modeled logic, not a tested household appliance.
