Chapter 1
Introduction
Before you begin
Welcome to The Rescue Tool Project! This story follows four Grade 7 learners and their teacher. Together they design, make and test a working model of a rescue tool. As you read, you will see the five steps that every technology project follows.
The scenario: Every day, cars crash on our roads. When a car is badly crushed, people can be trapped inside, and the doors will not open. Emergency workers use a special rescue system called the Jaws of Life to free them. Its strong blades can cut through metal and push it apart. The technology class has been approached for help. Their task is to design and make a working model of a Jaws of Life tool, to show how it works. The model must be powered by syringes and tubing, and it must use levers.
Background to the story
The Jaws of Life is not just one tool. It is a family of hydraulic rescue tools. A spreader pushes metal apart. A cutter slices through it. A ram pushes things away. In this story, the class builds a cutter.
This project is based on a scenario in the Grade 7 Technology part of the South African CAPS curriculum. It comes in Term 1, in the strand called Mechanical Systems and Control. In this strand, learners study levers, linked levers, pneumatics (systems moved by air) and hydraulics (systems moved by liquid). The Jaws of Life project brings all of these ideas together.
The scenario says that emergency workers use the Jaws of Life to rescue people who are trapped after an accident. Learners must design and make a working model of a rescue device that is powered by syringes and uses linked levers. The model can be simple. At the very least, it can show how one of the tools, a cutter or a spreader, works. Learners build it from everyday materials such as plastic tubing, syringes and cardboard.
Learners also keep a portfolio, a folder in which they record every step. The portfolio earns the theory mark, and the model earns the practical mark.
The five steps
Investigate: find out about the problem and test simple ideas. Design: sketch ideas and choose one to build. Make: build the model safely. Evaluate: test it and decide what to improve. Communication: share what you did, using a poster and a talk.
Meet the team
Lerato Maseko is a careful thinker who likes to sketch. Amina keeps the notes and asks good questions. Kabelo is practical, cheerful and quick to try things. Tiaan Venter measures everything twice. Mr Naidoo is the technology teacher. He guides the class and watches over safety, but the learners do the work.

Frequently Asked Questions
What is "The Rescue Tool Project" about?
A crushed car door will not open. In Mr Naidoo’s Grade 7 classroom, four learners have to build a tool that can show how rescuers cut through metal. Lerato, Kabelo, Amina and Tiaan start with two syringes, a clear tube and a bowl of water. They test what happens when one plunger moves, compare water with air, and turn their findings into a design for a working model of a Jaws of Life cutter. Along the way, they face the real challenges of a technology project: choosing materials, using levers and testing whether their idea works. Told through the five steps of the design process, this story brings hydraulics and mechanical systems to life for Grade 7 learners. Follow the team from the problem on the board to the tool they build and test.
