      Plan and design a data logger case

      Lesson details

      Learning outcome

      I can produce sketches that contain detailed annotations.

      Key learning points

      1. A data logger can collect data electronically.
      2. A micro:bit has switches that can record data.
      3. Group discussions provide solutions to design specifications.
      4. Annotations on sketches can explain how a design works.

      Keywords

      • Tally - a way to collect information

      • Data loggers - an electronic device that can collect information

      • Micro:bit - a microcontroller that can be programmed to do different tasks

      • Annotations - notes added to diagrams

      • Data - information such as numbers

      Common misconception

      Tally charts can only be completed on paper.
