Take a look around, can you find something that happens because of electricity ??
Example: lights, fans, phones, people
Q: Where is your heart ?
Q: Can you feel your heart beating ?
Q: What moves your heart ?
Q: Where does that electricity come from ?
A: Your brain !!
Similar to when we made the hair, pie tin, and balloons move using electricity
the brain makes the heart move.
Spark! - Suggestion#1
Have you ever created a spark between you and the door knob ?
You can assume that the voltage was between 7,000 to 10,000 Volts !!
Why didn't this harm you ?
When the static electricity discharged between your finger and the door knob,
the moving energy (i.e electric current) will only last for a very short time, it may last around one thousandth of a second (i.e 1 millisecond).
If the electric current lasted for a much longer time, your nervous system would be hyper-stimulated, making it difficult to let-go of the door knob or could severely affect your heart rhythm !
(i.e ventricular fribulation)
In most cases, It's not the Voltage alone that injures people,
it is the high electric current that can severely impact a person's life.
P.S It is perfectly safe to touch a door-knob !
Looking for Electricity
The discovery of static electricity was by the Greeks over 2,600 years ago around 600 BC.
The word "elektron" in Greek means amber.
Amber is petrified tree resin, and the ancients knew that when you rub an amber rod with a piece of cloth, the amber attracts small pieces of leaves or dust.
It is known that when people were bored at parties, women would rub their amber jewellery on their fur clothing and then touch frogs. The frogs would leap in desperation due to the static electricity that formed on the amber jewellery.
In Leaping Frogs, we do this experiment not with real frogs, instead with plastic frogs!
Leaping Frogs involves:
1. children are charged with static electricity using wool
2. children then touch a conductive plate
3. the electricity moves from them to a launch mechanism
4. the launch mechanism launches the frog
Leaping frogs also explores electricity and rotation, enabling children to build a custom bubble fan!
Listen to a sound in your environment
Q: Is the sound above?
Q: to your right?
Q: to your left?
Q: behind you ?
walk toward the sound
Q: As you walk closer, is the sound getting louder ?
Q: can you touch the object
Q: if so, feel the vibration
Q: is it a big vibration
Q: is it a small vibration

To create a Water Drum, you will first need a container as your drum.
A container made of metal will do nicely !
Your container will need a lid, so an empty Milo Tin or a Biscuit Tin will work fine.
Next, if the container has paper on the outside, please remove it.
You can now decorate the container with paint (or something else).
Ok, now we fill up the can with some water (not full).
Place the lid back onto the can.
Play your Water Drum !
And as you strike it, tilt the can to the side so the water is pressing on the side of the container.
In doing this, you will be changing the pitch of your instrument !
Congratulations ! you have now made an expressive, dynamic percussive instrument ! Your very 1st Water Drum.
AquaSonic - Suggestion#1
Create a Water Drum !
You may wonder why the pitch changes as you tilt the container ? The reason is this.
When you strike the drum, the energy from your hands (or stick) mostly ripples the walls of the container.
Because the container is metal, it wants to move back and forth very fast, in other words 'vibrate quickly'.
However, when you tilt the container, water is now pressing against the walls. The water opposes the rapid vibrations in the wall and slows them down.
The result ?
A slow vibration is perceived as a low musical pitch !
Review the childrens voice recordings.
Play, and then pause to ask the questions.
Q: was that a low pitch sound, big like a giant ?
Q: was that a high pitch sound, like a bird or a baby ?
Q: can the group match the low pitch sounds with their natural voices ?
Q: can the group match the high pitch sounds with their natural voices ?
Objects that are massive (e.g bear, truck, bass drum)
mostly vibrate slowly.
We perceive these slow vibrations as being low pitch sounds.
Objects that are less massive (e.g bird, flute, finger bell)
mostly vibrate quickly.
We perceive these fast vibrations as being high pitch sounds.

(3-5 yrs) workshop
Scribble Sound is a new take on an old concept.
Are you old enough to know what a phonograph is ?
If not, it is a device that reads the grooves on a vinyl record
and interprets the grooves as sound!
The same is true with Scribble Sound, instead computers interpret their scribble or drawings as sound art.
Scribble Sound Involves:
1. children draw a picture.
2. children scan the image.
3. the computer interprets the drawing as sound art.
4. children manipulate the image in turn the sounds.
Scribble Sound is a great example of digital art.
It is a looking-glass into the art of the future.
If you love interactive light & sound environments then look no further!!
The ChromaPhonic environment contains Light boxes, Microphones, Drums, and iPads.
The ChromaPhonic environment is completely reactive!!! controlled by speech or touch.
1. changing the motion of lights
2. using voice and touch to change light colours and intensities
3. playing a unique light & sound vowels game.
4. viewing voice as a living colour light spectrum
ChromaPhonics is the perfect bridge between Light, Sound, Movement, and Language.

(0-5 yrs) interactive environment
(3-5 yrs) workshop
In this techno age we are immersive in electronic gadgets.
PC's, Tablets, Smart Phones just to name a few.
But underneath all the complexity are some really simple concepts.
The Sonic Kitchen presents ElectroGraphic.
In this workshop, children have the opportunity to design and draw their very first circuit ! .
1. designing/drawing a circuit on paper using a graphite crayon
2. attaching an LED to the circuit
3. power-up the circuit with a 9V battery
4. experiment with varying the light intensity
Electrographic is an excellent project for learning about how electricity influences light.
