“Today, because knowledge is available on every Internet-connected device, what you know matters far less than what you can do with what you know.

The capacity to innovate — the ability to solve problems creatively or bring new possibilities to life — and skills like critical thinking, communication and collaboration are far more important than academic knowledge.

We need to focus more on teaching the skill and will to learn and to make a difference and bring the three most powerful ingredients of intrinsic motivation into the classroom: play, passion and purpose.”

Wire Diagram Switch & Circuit Prototypes
The Light-House Build & Blueprint
Student Experience
Students use circuit schematics to create a wire diagram for their house.
Students must get diagram approved by “the city” (teacher) in order to get project materials.
Students receive essential project materials (listed below) and must build prototypes of their series and parallel lights circuits, including switches.
They determine a way to power both prototyped circuits from the same voltage source.
Students design and build a functional model of their "dream house." Minimum requirements: 2 lights in series, 3 wired in parallel, and 1 stand-alone light, powered from a 9V battery with individual off and on switches.
Students create design poster showing wire diagram and blue building blueprint.
Material --
For each student:6 Christmas lights + wire3 paper clips6 bradsSection of cardboard or foam core
The cart
Big Idea
Diagrams allow engineers, architects, and contractors to analyze the performance of a circuit before building
it.
The three “branches” of lights are in parallel with each other so they may operate independently.
Engineering requires planning, prototyping, and
analysis.
Blueprints are accurately-scaled diagrams of
structures or machines.
Time One 55-min period One 55-min periodTwo 55-min periods, plus
time (~1 week) for students to work on projects at
home.

Construction and Design Brief
Student Experience
Students are introduced to the Culminating Activity (if
not done at the beginning of unit).
Students dissect a speaker and hypothesize the role of
each component.
Students experiment with magnets, wire, and paper,
plastic, or Styrofoam cups to prototype a single headphone
speaker.
Students build headphones using T4T materials.
Students prepare design brief defending their
product and documenting the engineering design
process.
T4T Material Speaker2nd Speaker
Thin-gauge wirePaper, plastic, or Styrofoam
cups or plates
2 magnets (if not already provided)
Additional wire (enough for ~35 loops in voice coil in
each headphone speaker)
Big IdeaWhat is required to create a speaker? What does each
component do?
Alternating current through a wire produces an alternating magnetic field, and therefore force, between the voice coil and permanent magnet. The speaker cone transfers the
vibrations from the voice coil to the air, producing sound.
To maximize volume and clarity, speaker cone
should be made from a lightweight material (low
mass = high acceleration, for a given force).
Speaker cone and voice coil assembly must vibrate
freely.Mono vs. stereo designs.

Voice coil
• Solenoid (coil of wire)
• Magnetic field changes with alternating current (AC)
• Strength of mag. field depends on number of coil loops
