Learning Objectives

Indicator: B9.4.1.1.3 - Design and make simple school technology projects using two or more of the mechanisms

By the end of the lesson, learners can:

identify at least three simple school projects that can be made using two or more mechanisms, and state the mechanisms each project uses.
select compliant and resistant materials, tools and equipment suitable for making a chosen project, and justify their choices.
plan and design a product folio showing the project sketch, materials list, tools, and the mechanisms to be used.
construct a simple school technology project using two or more mechanisms, following the correct sequence of measuring, marking out, cutting, joining and assembling.
test the finished project for correct function, record observations, and discuss possible modifications with peers.

Exemplars (from the NaCCA curriculum)

1. Identify simple school projects.
E.g., wall clocks, crazy snake, toy cars, bicycles, aeroplane/air craft, train, wind turbine/mill
2. Identify compliant and resistant materials, tools and equipment for making mock-ups/prototypes.
Note: Select the appropriate mechanisms based on the function of the project.
3. Discuss the reasons for the choice of mechanisms for a particular job.
E.g.
- Usage (easy to use)
- Availability of mechanism
- Cost of mechanism
- Skills of designer
4. Plan, design and prepare a folio of products/artefacts.
5. Make the product/artefact following the appropriate procedure.
E.g., Measuring, marking out, cutting, joining and assembling
6. Test the product for function and modifications.
7. Write down observations and discuss in, class in groups.
