Electric Circuits
What is an electric circuit?
A path in which electrons from a power source flow.
Name a simple project you can make with Makey Makey.
A banana piano.
What is reflection?
The bouncing back of light from a surface.
What is phosphorescence?
The emission of light from a material that continues after the light source is removed.
What is the chemical symbol for water?
H₂O.
Name the three main components of a simple electric circuit.
Power source (battery), conductors (wires), and load (bulb).
What type of material is needed to complete a Makey Makey circuit?
Conductive material.
What is refraction?
The bending of light as it passes from one medium to another.
What is fluorescence?
The immediate emission of light by a material when exposed to UV light.
What force keeps us on the ground?
Gravity
What is the difference between a series circuit and a parallel circuit?
In a series circuit, components are connected end-to-end, so current flows through each one in turn. In a parallel circuit, components are connected across common points, providing multiple paths for current
What programming language is commonly used with Makey Makey?
Scratch.
Which material can split white light into its component colors?
Prism.
Name a common use of phosphorescence.
Glow-in-the-dark objects.
What is the main gas found in the sun?
Hydrogen.
What happens to the brightness of bulbs in a series circuit if one bulb burns out?
All bulbs go out because the circuit is broken.
You either get or lose 400 points. You can keep it or give it to someone else
-400 points
What is the visible spectrum?
The range of wavelengths of light visible to the human eye.
Name a common use of fluorescence.
Forensic science, etc.
What is the name of the galaxy that contains our Solar System?
Milky way
Define ‘current’ in an electric circuit.
The flow of electric charge around the circuit.
What is the purpose of grounding in a Makey Makey circuit?
It completes the circuit, allowing the flow of electricity back to the Makey Makey board.
Define ‘wavelength.’
The distance between successive crests of a wave.
Why is it better for you to wear a white T-shirt on a hot summer day?
Light absorption
Which vitamin is produced when a person is exposed to sunlight?
Vitamin D.
What is the role of a switch in an electric circuit?
To open or close the circuit, thus controlling the flow of electricity.
What part of the Makey Makey kit is used to connect it to a computer?
USB cable
What happens to the speed of light when it moves from air to water?
It slows down.
What is the difference between phosphorescence and fluorescence?
Phosphorescence continues to emit light after the light source is removed, while fluorescence stops immediately when the light source is removed.
You either get or lose 400 points. You can keep it or give it to someone else
+600 points
