Title: Klondike Elementary School


1
Klondike Elementary School
to help make the education process more
fulfilling to the students of Klondike Elementary
School.
2
KES Groups
  • Eleven members in five groups
  • Four Seasons
  • Solar Car
  • Spell-Bowl
  • Quiz-Bowl
  • Stoplight

3
KES Four Seasons
  • Team Members
  • Scott Foreman
  • Scott Roper

4
Introduction
  • Four Seasons has two components
  • a model of the Earth-Sun system to illustrate the
    changing of the seasons
  • A student workbook to go along with the display

5
The Model
6
How It Works
  • Earth moves to desired season.
  • A second button activates the voice recording.
  • At any time the Earth can rotate about its axis.

7
What Needs to be Done
  • Improve voice circuit and amplifier.
  • Design the globe rotation circuit.
  • Improve the workbook.
  • Finish Earth revolve motor control circuit.

Introduction
  • The Solar Car project is
  • 1. an educational packet
  • 2. a hands-on demonstration tool
  • of energy conversion for the science curriculum
    of Klondike Elementary School.

10
Hands-on Demonstration
  • Solar car is the hands on demonstration portion
    of the project
  • The purpose of this demonstration is to show how
    mechanical devices can be operated by means other
    than a chemical battery.
  • It consists of a radio controlled car powered by
    solar cells and battery.

Spell Bowl Simulator
  • Team members
  • Nate Hribar
  • Neel Agrawal
  • Richard Charts

15
What is Spell Bowl?
  • Spelling competition that differs from
    traditional spelling bee in which students write
    down the words spellings after they are spoken
    and used in context
  • KES competes at grade levels 4-8 with teams of
    8-10 students.

16
Our simulator goals
  • Adequately prepare KES students for upcoming
    Spell Bowl competitions
  • Work through an interface that is both simple and
    user-friendly
  • Provide immediate feedback to the students
  • Structure in such a way that potential future
    simulator expansion is facilitated

17
Implementation
  • Audio files for each word will be stored in a
    central database
  • The students will be prompted with audio for each
    word, and will then have 20 seconds to enter
    their spelling
  • Simulator is web-based and compact

18
Current GUI

21
Whats Next?
  • Continue working on the implementation of the
    code
  • Testing Revision
  • Enter text and audio for each word into a central
    database using automated audio translation tools

22
Future Development
  • Extend simulation to math and science bowls
  • Acquire domain name of www.bowlsimulator.com
  • (currently available)

23
KES Quizbowl
  • Project Partner Klondike Elementary School
  • Team Members
  • Steven Llewellyn
  • Joshua Pruitt

Purpose To create an educational device which
will encourage healthy competition while learning.
24
Mid-semester Progress
  • Quizbowl Progress
  • Researched different wireless approaches.
  • Chose new wireless parts based on suggestion from
    Professors and previous research.
  • Pricing of body shells and other components
    needed for working prototype.
  • Modifying PLD code for new parts.

25
How Does It Work?
  • Uses programmable logic devices
  • Logic is implemented using ABEL
  • Lights are powered from 110 Vac
  • PLDs are connected to a 5V source
  • A clock signal is created from a 555 chip with
    resistors and capacitances
  • Wireless handheld buzzers containing transmitters
    and main station containing game controls and all
    receivers.

26
Stoplight
  • Team Members
  • Yu Gene Wong
  • Karl Scheel

27
What It Does
  • Basic idea is to control students noise in
    cafeteria.
  • Takes noise inputs through a microphone sends it
    to the microprocessor, and it determines if its
    too noisy.
  • Lights changes based on the noise level.

28
Circuit Diagram
29
Roadblocks
  • Stability problem with amplifier circuit.

30
Whats Next for This Semester
  • Currently software part of the project is
    completed.
  • Need to change or fix the amplifier design.
  • Need to adjust potentiometers in KES cafeteria.
  • Need to solder parts onto board.
