Secondary Schools

 

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)

Secondary

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. Suitable for homework or for 45-60 minutes sessions. Suitable for pupils aged 12-16. (45-60 mins)

Secondary School Quick Challenges

Four sets of 13 (Baker’s Dozen) challenges each taking 5-10 minutes.

Set 1     Set 2

Set 3     Set 4

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 + )

2,3,5,7,11,13,17,19

….997

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.

BBC Micro-bit Traffic Lights

Using the new BBC Micro-bit 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 Micro-bit. The example uses a relay to turn off green lights when the yellow ones are on.

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 + )
