Q1a. Can you make the energy ball work?
Yes, we can make the ball work by placing our fingers on the metal plates
Q1b. What makes the ball flash and hum?
Since there is a hole in between the two metal plates, we each need two fingers that is connected to connect the circuit.
Q2. Why do you have to touch both metals contacts to make the ball work?
Our fingers which acts as conductors to allow the electrons to run through our body to connect the circuit.
Q3. Will the ball light up if you connect the contacts with any materials?
No, not every object act as a conductor.
Q4. Which materials will make the energy ball work? Test your hypothesis
Certain objects which act as conductors. For instance, salt water and metal.
Q5. This ball does not work on certain individual what could cause this to happen?
That event occurs when only one side of the metal plate has been touched. Or if you are nor charged enough, because of contact with positive or negative charges. And you need to keep giving electrons to it from stealing electrons from others.
Q6. Can you make the energy ball work with all 5 ~ 6 individuals in your group? Will it work with the entire class? It does work, the currents just connect through all of us. It will work with the entire class as long as we are all connected.
Q7. What kind of a circuit can you form with one ball?
A series circuit, because it only goes in one direction.
Q8. Given 2 balls (combine 2 groups): Can you create a circuit where both balls light up? [1/3]
Yes, we can create a circuit.
Q9. What do you think will happen if one person lets go of another person's hand and why? [2/3]
It does not connect so the circuit is opened.
Q10. Does it matter who lets go? Try it. [3/3] No, if one of us lets go, it doesn't work.
Q11. Can you create a circuit where only one ball lights (both balls must be included in the circuit)? [1/2]
Yes, using a parallel circuit.
Q12. What is the minimum number of people required to complete this? [2/2]
At least one person.
