Cozy energy ball~
Yes, I can make the energy ball work.
To make the ball flash and hum, a complete circuit must be made. We are able to conduct some electricity so by putting your fingers on both parts of the metal, it completes the circuit.

Q2: Why do you have to touch both metal contacts to make the ball work?
One must touch both metal contacts to make the ball work to have a complete path for the positive charge flow to move to the negative terminal.

Q3: Will the ball light up if you connect the contacts with any other material?
This depends on the conductibility of the material. If the object is made of metal (i.e. fork), then it is a able to light the ball up because it is a good conductor. Bad conductors, such as a desk, is a bad conductor and cannot make the ball light up.

Q4: Which material will make the energy ball work? Test your hypothesis.
Our group assumed that metallic objects would make the energy ball work because they are good conductors of electricity. Our hypothesis was right; the metal ring of a binder was able to make the energy ball work.

Q5: This ball does not work on certain individuals, what could cause this to happen?
Dry skin -- since the current flows out from the positive terminal (one finger) to the negative terminal (other finger), the person will be able to complete the circuit if he/she has enough moisture. This is because the salt content and other impurities in our bodies and fingers are able to conduct electricity, so having dry skin (not enough moisture/impurities) causes the person to be less of a good conductor.

Q6: Can you make the energy ball work with all 5-6 individuals in your group? Will it work with your class?
Yes, I can make the energy ball work with all the members in the group.
It will work with the entire class, as long as the circuit is complete (we're all touching pinkies).

Q7: What kind of circuit can you form with one energy ball?
A simple circuit can be formed with one energy ball.
A simple circuit can be formed with one energy ball.
Q8: Given two balls (two groups): Can you create a circuit where both lights up?
Yes, by adding another ball into the simple circuit, you have just created a simple series circuit!

Q9: What do you think will happen if one person lets go of the other person's hand?
If one person lets go of the other person's hand, then both energy balls will not light up/hum. This is because a circuit is a complete path, so if one person lets go, the balls will not light up/hum.
If one person lets go of the other person's hand, then both energy balls will not light up/hum. This is because a circuit is a complete path, so if one person lets go, the balls will not light up/hum.
Q10: Does it matter who lets go?
No, this is because in a series circuit, it is still only made up of one path, so whoever lets go will still disconnect the circuit.

Q11: Can you create a circuit where only one ball lights up?
Yes, and this circuit is called a parallel circuit.
Yes, and this circuit is called a parallel circuit.
Q12: What is the minimum number of people required to complete this?
One person minimum is required to complete this. The person can hold one energy ball in one hand, and the other in the other hand, and the finger is the switch. In each hand, the circuit is complete by using 2 fingers; one for each metal strip. The switch can be turned 'off' by lifting the finger off of one circuit, therefore having only one energy ball flashing/humming.
