Multiple Select

If I give you a light bulb, a battery and some cables (like in the picture), and I want you to make the bulb light up, what do you have to do next? (Choose all correct options)

• Connect the two cables directly

• Connect the two cables with something that conducts electricity

• Nothing. It'll work just like that

Multiple Choice

What object would best complete this circuit?

• A battery

• a piece of yarn

• an insulator

• a conductor

Multiple Choice

The picture shows a carbon atom with its protons, electrons and neutrons. What is true about this atom?

• It's positively charged

• It's negatively charged

• It's not charged, it's neutral

Multiple Choice

What if I add another electron?

• Still neutral

• Now it's positively charged

• Now it's negatively charged

Multiple Choice

How would I make it POSITIVELY charged?????

• Add a proton

• Remove an electron

• Nothing. Can't be done

Multiple Choice

What keeps electrons "in orbit" around the nucleus?

• Gravity

• They're attracted to the positive nucleus

• Inertia

Multiple Choice

What happens when they get close to each other?

• Attract

• Repel

We know this as Static Electricty

But the more scientific term is...

Go to: tinyurl.com/ycknked3 and construct the circuit as you see it in the picture

​

​Then figure out which of the objects are conductors
