Learning about electricity
In this Grade 3 science collection, you can practice Electrical conductors and insulators. Choose a game above for a short activity, or explore the examples below before you play. The full guide for each game explains its controls, gives more examples and includes a free printable for practice away from the screen.
Talk it through
Start with something you can observe. Ask your child to describe the evidence for a choice, then compare a second example. A game practices vocabulary and reasoning; practical observation and investigation matter too.
Ask: “What clue helped you decide?” Give your child time to explain. Return to an example after playing and ask whether they would approach it differently.
Electrical conductors and insulators
Will a bulb light through a paper clip or a plastic ruler? A free Grade 3 science game about electrical conductors and insulators, with a printable game and worksheet.
Try an example: Which of these is a good electrical conductor: a cork, a cotton sock, aluminum foil or a wooden spoon?
Only one of these is a metal. Aluminum is a metal.
Show the answer
Aluminum foil.
What to look out for
Thinking only magnetic metals conduct. Test a brass key or foil in a circuit: they are not magnetic but the bulb lights.
Practice away from the screen
- Look at a plug or charger together (unplugged). Point out the metal pins and the plastic case.
Curriculum connections
Electrical conductors and insulators
Suggested grade 3 practice, selected by skill and reading demand. US states and schools teach these topics in different grades; this is not a state-standards alignment claim.
Next Generation Science Standards teaching connection: PS3.B: electrical energy transfer. Conductor vocabulary can prepare learners to explore electric circuits. The linked Grade 4 expectation requires evidence about energy transfer; sorting materials alone does not demonstrate that performance. Read the framework.
Questions families ask
Where should we start with electricity?
Start with Electrical conductors and insulators. Look at the worked example together, then try a round. If the task feels unfamiliar, use the full game guide or its free printable before trying again.
Does this cover everything taught at this level?
No. These games provide focused practice. Grade suggestions do not replace your school’s curriculum, and any Common Core connection applies only to the skill described.
