Electric Charge, Attraction & Materials — Drills · Grade 6 Science
Chapter: Electricity, Magnetism & LightWhat these drills covers
By the end of Electric Charge, Attraction & Materials you should be able to:
- I can explain what happens to electrons when two materials are rubbed together.
- I can predict whether two charged objects attract or repel.
- I can explain why a charged balloon sticks to an uncharged wall.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: net charge, conductor, evidence, system boundary, uncertainty.
Problem 1
- A sample with missing measurements has proved those values are zero.
- Rubbing creates electric charge from nothing.
- Attraction always proves two objects have opposite net charges.
- net charge: The imbalance between positive and negative charge in the chosen system.
Answer and explanation
net charge: The imbalance between positive and negative charge in the chosen system.
The imbalance between positive and negative charge in the chosen system.
Problem 2
- conductor: A material in which charge can move relatively readily under stated conditions.
- Attraction always proves two objects have opposite net charges.
- Rubbing creates electric charge from nothing.
- Repeating any method makes every causal claim true.
Answer and explanation
conductor: A material in which charge can move relatively readily under stated conditions.
A material in which charge can move relatively readily under stated conditions.
Problem 3
Answer and explanation
No. A shifted distribution in neutral material can also produce attraction; additional evidence is needed.
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
It can affect charge movement and the observed interaction, so a difference cannot be assigned to material alone without comparable conditions.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
