Cub Scouts Pack 207 visited the museum with a group of students from 2nd grade to 5th grade. Volunteers Dave Brown, Chris Curtin, Robert Dexter, Pat Green and Gary Johnson staffed the event and demonstrations.

Gary Johnson welcomed the visitors in our classroom, gave a brief overview of the museum, and circulated various electronic components for a hands-on look.

The students were then divided into small groups and rotated through five hands-on demonstrations. Volunteer Pat Green demonstrated LCD technology with a microscope to view the pixels on a laptop display. A monitor displaying a video is able to be lifted away from the backlight  to demonstrate the translucent nature of the LCD panel.

Volunteer Dave Brown demonstrated sound and waves starting with a speaker driven at sub-audio and audio frequencies. An electric guitar demonstrates different waveshapes and the effect of shortening wavelengths. The microphone allowed the students to view both wave shapes and amplitude envelopes. Finally the Theremini provided significant hands-on experimentation.

Volunteer Chris Curtin demonstrated our flashlight box showing both additive and subtractive color. The LED demonstration showed instrumentation to vary and measure voltage to a RGB LED which shows the color sequencing of the red, green, and blue LEDs with increased voltage to produce white, and the inability to dim with voltage. A pulse generator and oscilloscope demonstrated using pulse width modulation to vary brightness and the inability of the eye to perceive flicker.

Volunteer Gary Johnson demonstrated graphics on the 4052 and showed the underlying program. Various different images were displayed including Instant Art. The 4016, with it's larger screen size and resolution, provided lots of entertaining art.

Volunteer Robert Dexter demonstrated using an oscilloscope to measure velocity using our Time of Flight exhibit. The students could measure the different speeds at the three different angles of the ramp. They also were able to measure our the high speed of electrons in a wire. The students were then able to create their own artistic display with our Scope Art exhibit.

We received this nice thank you card and a tin of cookies.
