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.

KES Epics TeamSolar Car

• By Keith Gossman
• Mike Hsiu

9
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

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

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.
