This unit is about Materials and Electricity. Students will work in a collaborative way by means of the project-based learning methodology. They will have to design, draw and build a vehicle using some waste materials (soap bottle for the bodywork, caps for the wheels…) and electrical components (motor, wire, battery…). This vehicle will be driven by a 3, 5 or 7 bladed propeller 3D printed, that will be screwed to join the motor throughout a standardised bottle cap.
- To design a prototype to find a solution to a technical problem throughout the technological process.
- To create the required reports in order to plan and build the prototype.
- To interpret technical drawing, plans and sketches as an information element of technological products.
- To represent using views and perspectives objects and technical systems, throughout sketches and plans with standardisation criteria regarding scales and annotation.
- To identify and manipulate the workshop tools in forming operations of technical materials.
- To complete the project worksheet attending health and security rules.
- To design basic electric circuits by means of specific software and using standardised symbology and to experiment with the elements that configure them.
- To design and assemble basic electronic circuits using bulbs, buzzers, LED diodes, motors, batteries and connectors.
- To describe the characteristics of technical materials comparing their properties.
- To explain how to identify the mechanical properties of technical materials.
- The Technology teacher will prepare the worksheet and digital presentation to introduce the project to the students.
- Both materials and tools will be ready to use in the workshop.
- A template for the report will be given to the students so that they can fill it in whilst they are in the design and build phases of the Technical Process.
- The teacher explains the topic and objectives of the project.
- Students must know previously the basics of technical drawing, technical materials properties, electricity, tools, health and safety rules in the workshop and the different parts of a project report.
- Explanation of 3D printers functioning and 3D design guide.
- Split up the students intro groups of 3.
In each group of 3 students they will have to design and build a vehicle and deliver the technical report of this project. The steps to follow are:
- Design and draw the vehicle and wiring diagram: plans using scales and annotations.
- 3D print the propeller.
- Build the vehicle.
- Evaluation of its functioning: speed, direction, friction.
- Delivery of the technical report of the project, including requirements, plans, wiring diagram, worksheet, used materials and tools, and individual feedback about the didactic unit.
