The IET Coventry and Warwickshire Network has 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 teachers
guides, visual aids and, where relevant, pupil guides. Challenges In A Box are copyright. 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, derrick.willer@ietvolunteer.com

|
|
Burglar
Alarm Secondary |
An
introduction to electrical circuits using low cost materials. About 30-60
minutes as individuals or small teams. I used this for a KS3 STEM Club (12-14 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. |
|
|
|
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, sticky-tape, 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 10-15. (2½ hours) |
||
|
Replacing
The Family Car |
Pupils
should investigate the whole-life carbon footprint of a car using the
internet. They should draw graphs pie-charts, 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
12-16. (Homework, 4+ 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, spread-sheets,
etc. can be used and make this relevant to the challenge subject. Suitable
for pupils aged 12-16. (In-school 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 12-16. (12+ hours) |
|
|
|
Card
Tricks |
What are the maths behind these three card tricks? Pupils can
work alone or in small groups to discover how these card tricks work.

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
To Computer Programming |
Utilising
the 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 12-16. (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 12-16. (1½ hours +) |
|
|
|
Prime
Numbers |
This
project is aimed at learning about programming by developing a computer
program to test if a number is prime and then to extend this to list all
prime numbers up to a given number. Suitable for pupils aged 12-16. (1 hour + ) |
||
|
Pythagorean
Triangles |
We all
know that a 3,4,5 triangle is a right angled
triangle, a Pythagorean Triangle. In this project pupils write a computer
program to discover other whole-number Pythagorean Triangles up to a given
length of the shortest side. Suitable for pupils aged 12-16. |
|
|
|
Fun With Phiziks and Che Mystery |
Ten
activities including Fizzy Chemistry, Make a
Thermometer, Magnifying Glass, Bending Water, Speed even though you are

The
Safety Deposit Vault |
This project is based on a real spread-sheet
for a company in Birmingham. The spread-sheet is
complex and must be mail- merged with invoices and overdue letters in a
word-processor. Suitable for pupils aged 14-18. 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
in-depth 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. |
