Electric Circuits
Name:
Website #1 – Using Electricity – (click on the arrows to go to the
next step – answer each question after each activity)
1) What makes the bulb light? battery
2) How does it make a difference? it makes a difference by
sending the elicitral charge in the other direction.
3) How can you make it turn? yes
4) How does this make a difference? yes it goes the other way.
5) How many questions did you get right on the quiz? 10 out of 10
Website #2 – Circuits and Conductors
1) Which completes the circuit? a rubber key and a coin.
2) What did you notice about the brightness of the two bulbs? that
the brightness is very low.
3) What did you notice about the brightness of the two batteries
and one bulb? that the bulb is super bright.
4) What happens with 3 batteries and 1 bulb? the bulb burnned
out.
5) How many questions did you get right on the quiz? 10 out of 10
Website #3 – Changing Circuits
1) What did you do to make a circuit with 2 dimly lit bulbs that can
be turned on and off? one battry and two bulbs.
2) What did you do to make a circuit with 1 very brightly lit bulb
that can be turned on and off? two batterys and one light bulb.
3) What effect did swapping the wire for a longer coiled wire have
on the bulb’s brightness? it made the bulbs brightness go down.
4) What did you find out experimenting with the model circuit? that
it showed how it makes a difference to the circet.
5) How many questions did you get right on the quiz? 10 out of 10
Website #4 – Electrical Circuits
1) The negative terminal of the battery has many electrons.
2) The battery pushes electrons from the negative terminal
through the switch, the light bulb, and the wire into the
conductors terminal (where there are not many electrons).
3) A special kind of wire inside a light bulb is called filment.
4) conductors carry electrons very easily.
5) Copper wires are a good conductor. (Delete the wrong answer)
6) insolators do not permit electrons to flow through them.
7) Silver is a good insulator. (Delete the wrong answer)
Website #5 – Electric Circuits
Do each of the 5 useful info (i), activities (green arrow) for each
activity.
Section 1
1) A power source can be either a circet or battery.
2) Both batteries in a circuit have to be facing the same or
opposite direction.
3) What did you learn from the activity?
Section 2
1) A conductor carries electricaty.
2) An insulator stops electricaty.
3) What did you learn from the activity? what i learned was that
conductors carry electricaty and an insolator stops electricaty.
Section 3
1) Switches allow you to make or break a circuit.
2) What are two types of switches? toggle switch or push switch.
3) What did you learn from the activity? that there are two typs of
switches the toggle switch or the push swithch.
Section 4
1)
2)
3)
4)
5)
If you add more bulbs to a circuit, the bulb will glow darker.
If you add more cells to a circuit, the bulb will glow brighter.
If the wire gets longer, the bulb gets dimmer.
If the wire gets shorter, the bulb gets brighter.
What did you learn from the activity? that bulbs can go different
ways like brighter or dimmer by just changing the wire.
Section 5 - Extra Credit
1) What are used to show a circuit that anyone can understand?
wires,bulbs, and batterys.
2) Draw and label one component.
