Electric House Project

For our science 9 final project, we were asked to build a electric house with cardboard, wires, and switches to make sure they activate. I was surprised that all our circuit works.

  1. You have three lights bulbs. All have the same intensity when lit. Explain how you can prove to a classmate that they are connected in series by unscrewing one light bulb. Support your answer. 

When you unscrew the lightbulbs or turn them off, the electrons have no home to go to and no circuit to complete therefore letting the electrons fall off and have to go back not lighting the rest of the lightbulbs and pushing the electrons through the full circuit.

2. You have three light bulbs. All have the same intensity when lit. Explain how you can prove to a classmate that they are connected in parallel by unscrewing one light bulb.

When the lightbulbs being in parallel, it means multiple other lightbulbs are still available to complete the circuit, and thus allowing them finish the loop by going through the other bulbs which are attached.

3.You have three light bulbs. Two are connected in parallel. This parallel combination is connected in series with the third light bulb. Describe the relative intensity of each bulb. Support your answer.

When there were 3 light bulbs connected in series, the power of each one will become equally as strong, why because there is one battery available for every light bulb. Therefore, they held no different intensity between each bulb.

4.In question number three, describe the relative intensities of the two remaining lit bulbs if one of the bulbs in parallel was unscrewed. Support your answer.

If one bulb was unscrewed both would still receive the equal charge as the battery is available for every light bulb


Our “Stuff” and the Spheres Mind Map


Behavior/Item: Electric Guitar
Raw Materials Production/Manufacturing

–          Maple or mahogany, and fretboards are typically made from maple, rosewood, and, occasionally, ebony. High-end electric guitars sometimes have one-piece wooden bodies, but many guitars are made from several pieces of the same wood species glued together.

–          A nickel/steel alloy string has a slightly more subdued sound than a pure steel string, with steel typically being brighter. The two main types of electric guitar strings have windings made from nickel/steel alloy or pure stainless steel.

–          The usual guitar paints are lacquer paints (hard paints) made from polyester, polyurethane and nitrocellulose because these continue to cure over time, are durable and enhance the guitar’s sound. Nitrocellulose paint is known as a lacquer, and it is a hard paint that has long been used on musical instruments.


–             Wood is selected, inspected, and processed to be made into bodies, necks and fingerboards. Sometimes it must be cured first in a conventional or vacuum kiln to maximize its stability. Curing can take as long as a week, and it relieves stress and wetness. The wood that will be made into a body is loaded onto a scissors lift and transferred to a conveyor where it is planed on both sides. It then moves down to the cut-off saw worker, who cuts the wood to size. From there, the wood is sent to a machine called a KOMO, a computer-controlled router that drills weight relief holes to make the wood lighter. The machine also cuts a channel in the wood where wire will eventually be placed.

–           The wood then goes back into the rough mill, where it will have a maple top and mahogany back glued on in a glue mill under 900 lb (408 kg) of pressure. It is then placed on a glue wheel to dry for four hours. Up to this point, the wood is a square block. When dry, it is ready to be shaped. It is sent back to the KOMO, which is programmed to cut the periphery into the desired shape. The KOMO also routs the back electronic pockets.

–          The body then goes to the body line for its final shaping. First, a worker sands the body by hand with sandpaper, then it undergoes a process called “rabbeting.” Rabbeting involves first making a machine cut that will accommodate the binding that the body needs. The worker maneuvers the body while the machine makes the cut. The body then moves down the line to the binding station. The worker takes the binding material, drenches it in glue by pulling it through a glue box, then wraps it around the rabbet cut made in the body. The worker then ties the body completely with rope to hold the glued binding material in place. Then the body is hung overnight to dry.

Transportation Sale/Consumption/Use

–          A guitar in a case will run you somewhere between $100 to $150 to ship. Yes, it will cost that much. A guitar shipped in a gig bag will be around $75 to $90. Obviously, this varies dependent on how far it must ship.

–          If you’re flying a commuter plane, your guitar is most likely going in the hold (unless you can talk the attendants into letting you take up the whole coat closet); but if it’s a bigger plane, there’s a chance you can take it on as a carry-on item. They must fit their carry-on items around your guitar.



–          The power consumption is always much higher than the power output. In this case the output power is 85 watts RMS and the power consumption are 260 watts.

–          An electric guitar is a guitar that uses one or more pickups to convert the vibration of its strings into electrical signals.

–          Typical costs: A basic electric guitar with amplifier and cord starts around $200-$400 for a beginner’s outfit; a better-quality kit can run $500-$2,000, and high-end electric guitars are $2,000-$5,000 or more for the instrument alone

Connections Between Effects

e.g. if your behaviour is “paper use” and you identified deforestation as an effect on the biosphere, you could also connect deforestation to soil erosion in the lithosphere


–          Consumption and the cost how much electricity you use. Electric guitar uses 260 watts per hour and that energy cost 246.74 per year.



How can you reduce the negative effects of your chosen behaviour?

Small scale solutions (personal):

–          I would rather use acoustic guitar since they don’t use electricity

–          Maybe make your own guitar by using cardboard boxes and rubber bands. That way you don’t use trees/wood and all kinds of raw material.
