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 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. 

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) 

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) 

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) 

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. Suitable for homework or for 4560 minutes sessions.
Suitable for pupils aged 1216. (4560 mins) 

Secondary School Quick Challenges 
Sets of 13 (Baker’s Dozen) challenges
each taking 510 minutes. 

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 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 +) 

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 1216. (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 wholenumber Pythagorean Triangles up to a
given length of the shortest side. Suitable for pupils aged 1216. 


Fun With Phiziks
and Che Mystery 
Ten activities including Fizzy
Chemistry, Make a Thermometer, Magnifying Glass, Bending Water, Speed even
though you are sitting still, Oxygenetics, Mento®
Fountain, Why is Statue of Liberty Blue, Acceleration, Plastic Milk 

BBC Micro:bit
Traffic Lights 
Using the new BBC Microbit and Python
code to manage a single traffic light, then a Cross Roads set, finally to
make the traffic lights using recycled materials. The problem to solve (with
an answer) is that there are four states for the Cross Road Traffic Lights
and only three outputs from the BBC Microbit. The example uses a relay to
turn off green lights when the yellow ones are on. 


Funny Maths 
Exploring some unusual arithmetic,
geometry, etc. used by ourselves and maybe, aliens. Using Thales Theorem,
Hippocrates of Chios, Mesolab Compass, multiplying using your hands and unusual
multiplication by some other races. 

The Safety Deposit Vault 
This project is based
on a real spreadsheet for a company in 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. 

Tricky Mathematics

pupils, teachers and STEM Ambassadors 

Careers Presentation 
Derrick Willer MBE summarises his
career working as an engineer in many countries across the world. He then
leads the pupils to prepare a bid for funding for his son’s IET Award winning
