Locally in Coventry and
Warwickshire we have developed the following Challenges In
A Box for school teachers to use to assist in educating pupils of various ages.
We are keen to have feedback and new ideas for these challenges.
Each challenge has visual aids
and, where relevant, pupil guides and teacher guides.
Challenges In A
Box are copyright © Derrick Willer.
However you are free to copy for use in schools and for
instructing children of school age and for use by children of school age.
Please feedback to: Derrick Willer, dw@dwiller.com
However,
I suggest that you give a small donation (e.g. £20,
$30) to the Memusi Schools in remote Kenya so that
they can install electricity and then get computers.

Project 
Description 
Burglar
Alarm Secondary 
An introduction
to electrical circuits using low cost materials.
About 3060 minutes as individuals or small teams. I used this for a KS3 STEM
Club (1214 year olds) giving them a set of the same
materials and challenging them to make the burglar alarm without any guidance
whatsoever. Not even the concept of a trip wire. 


Table
Tennis Ball Launcher 
An education challenge. We have 12 kits available for use in schools in
Coventry and Warwickshire. (30 mins for basic launcher kit – up to 1½ hours
for loader for the launcher made from recycled materials provided by the
school) Email Derrick Willer dw@dwiller.com availability. 


Paper
Catapult 
Pupils in
small teams are asked to design, budget and then make
a catapult out of recycled paper. Recycled materials are free but nuts,
bolts, elastic bands, stickytape, etc. cost money. They catapult a ball at a
set of skittles three times, scoring a maximum of 89 points. Additional
scores depend upon the accuracy of their budget and the innovative nature of
their design. Suitable for pupils aged 1015. (2½ hours) 


Why
Lag Your House? 
A simple card based exercise for younger pupils to learn how insulating
your home can improve heating and save on energy. Suitable for pupils aged
513. (60 mins) 


Bridges 
A paper based exercise suitable for 713 year old pupils. Pupils
make a bridge
out of paper into a U"
shape and find out how much
weight (pennies or model cars) it will take with different depths of the
"U" versus the remaining area for the bridge. They graph the
results. The project is then extended to bridge the gap between
two chairs with
paper, sticky tape, etc. costing
them "money" – e.g.
cheapest to hold a 100gm weight wins. (30 mins) 


Replacing
The Family Car 
Pupils should
investigate the wholelife carbon footprint of a car using the
internet. They should draw graphs piecharts, etc. comparing buying a new car
versus keeping the old one. Internet research, spreadsheets, etc. can be used
and make this relevant to the challenge subject. Suitable for pupils aged
1216. (Homework, 4+ hours) 


House
Of Gadgets 
For 9  13 year olds. An exercise to understand sustainability and
conservation. Pupils imagine what will happen if rubbish is not collected.
Then there is a short story about conservation. The pupils decide on a gadget
to make and are given recycled materials to make a mockup of it. (2½3
hours) 


Hydrogen
As A Fuel 
Hydrogen
powered cars, etc. are already working at Birmingham and other universities.
Pupils make hydrogen and oxygen and test them. They are then asked to work
out the best place to make hydrogen using sunlight. They should work out the
costs of transporting from source to point of use  including
compressing/liquefying the gas. Internet research, graphs, spreadsheets,
etc. can be used and make this relevant to the challenge subject. Suitable
for pupils aged 1216. (Inschool experiment, 30 mins, Homework 4+ hours) 


Fan
or Turbine Efficiency 
Pupils should
make a fan and work out its efficiency at various blade angles and numbers. A
Design Council Project finalist utilised a boat propelled by the
fan pulling against
a weight suspended over a pulley. But pupils can use any other method. Project report with
graphs, etc is required. Graphs,
spreadsheets, etc. can be used and make this
relevant to the challenge subject. Suitable for
pupils aged 1216. (12+ hours) 


Paper
Towers And Bridges 
Versions for
Primary and Secondary Schools. Approx. 30 – 60 minutes. Secondary school
pupils in teams are judged on design, budgets, actual spend, and presentations.

Robot
Challenge 
This project
challenges teams to build a model robot from K’nex
kits. Meccano or other construction kits. It is aimed at
pupils ages 10 to 14 (years 5 to 9). The project could also be used to
introduce primary school pupils to their secondary school with
"mentors" for each team from the secondary school. It was first
developed and run at Jaguar Cars Visitor’s facility at Castle Vale,
Birmingham, with some 150 thirteen year old school
pupils in teams of six. (1½ hours +) In the lunch period we were entertained
by Prof. Carl Chinn MBE, the famous Birmingham local radio celebrity with
some of the pupils and some teachers being interviewed on BBC West Midlands
Radio. We are
indebted to Jaguar Cars and BBC West Midlands Radio and
Prof. Carl Chinn MBE for
their valued assistance. 


Introduction

Basic programming language, pupils learn now to
write and test a program initially to add, then to subtract, multiply and
divide two numbers. Suitable for pupils aged 1216. (1 hour +) 


Code
and Decode 
This project
is aimed at learning more about programming by developing a computer program
to code and decode a message. Pupils will be able secretly to send a coded
text document attached to an email to a friend who, when given the correct
key, will be able to decode the message in the text document. Alternatively they can save secret data in coded format.
Suitable for pupils aged 1216. (1½ hours +) 


Pendulums

Birmingham. The spreadsheet is complex and must be mail
merged with invoices and overdue letters in a wordprocessor. Suitable for
pupils aged 1418. There is a model answer. An extension is to utilise a
database such as MS Access  this is very relevant to the challenge subject.
(1 hour + ) 


Microsoft
Access Tutorial My Holiday Home 
This tutorial
provides detailed instructions on creating a Microsoft Access database using
an example that manages the lettings of a holiday villa in France or Spain. It will
provide students with an indepth understanding of MS Acess
and an ability to design and construct their own databases to benefit
themselves and their employers. Each stage is
detailed in minute detail to guide
the student through to a completed database. The tutorial starts with
creating the database, adding Tables for customer Names
and Bookings. Then Queries to enable us to combine tables and sort
into sequence. Students can
proceed at their own pace but the typical minimum time for the entire
tutorial is of the order of six to eight hours, however some can be completed
as "homework". The tutorial requires downloading Microsoft Access
2013 or later versions.
