  • 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)

12 May 2015 Question by: Marian Holland
Q. Do you have any teacher notes/hints on the Rapid Moisture Detector Project please? I would like to attempt this project but am a one person department so would like some help. Thanks,
A. Hi Marian, thank you for your question. The teacher notes can be found here.
