Rapid Moisture Tester Project Components - Set of 5 (No PCBs)

Kits of components to build a functional Moisture Tester that can be used to tell if pot plants require water.

The kits contain all the electronic components required, except the PCBs, which are available separately. This provides the option to buy ready-made PCBs or for students to make their own.

The moisture tester project has been designed as an introduction for Key Stage 2 & 3 students to the use of resistors and transistors in circuits.

* Students start by investigating the care of house plants and the problems

associated with incorrect moisture content of soil

* Downloadable information and activity sheets then guide the students

through a series of exercises to build background knowledge in the use of

resistors and transistors in circuits

* For manufacture, the project allows the teacher to select from two

alternative methods of circuit construction, either self adhesive copper tape

onto card or on a printed circuit board (available separately) see order code

34-0635

* Upon completion of manufacture students are then guided through an

evaluation of their work

* They also have the option of producing a 3D model using high density

polystyrene foam illustrating how they might develop a final product if the

design were manufactured commercially

* Project notes are available for free download and are designed to be

photocopied for class use

* They include both detailed student and teacher notes, which contain

suggested lesson plans, mapping to the National Curriculum and a series of

structured homework assignments to support the work in class

* The component kits are supplied in multiples of 5 and include:

* All components including LEDs, battery clip, resistors and transistors

* The project can be produced using PCB available or self adhesive copper

tape (see PCB products section)

* Suitable for Key Stages 2 & 3 (ages 7 to 14)

Requires 1x PP3 battery (not included).
