ICT at key stage 3    (Year 8)

Unit 8: Public information systems
Section 4: Activity 4

QCA

Objectives

Children should learn:
  • how basic sensors work and how data is stored and transmitted
  • to download and store primary data
  • how data is stored in ROM in a specific format and can be downloaded to the computer

Activities

Outcomes

Children:
  • Introduce the principles of remote sensing using two different examples, eg how an automatic weather station measures rainfall and measures wind speed by sensing rotations of the anemometer by light.
  • Ask the pupils to work in groups to collect data from their chosen source(s), downloading, copying and storing data as appropriate, ready for further analysis. Ask the pupils to write up the completed process individually.
  • Remind pupils that data must always be used carefully, eg weather station data can contain incorrect data, either through a weakness in the system or the way an element is sensed.
  • Encourage pupils to undertake independent research, using knowledge of how texts and databases are organised and using appropriate reading strategies.
  • present results of analysis in ways that inform the specification of future working
  • collect, download or save appropriate data from datalogging or other sources
  • understand that remote sensing produces data in particular formats and know what these represent

Points to note

  • An automatic weather station is an ideal piece of equipment for this activity, but if there is not one available, temperature and light sensors could be used to measure local information.
  • Homework could involve pupils identifying different remote sensing applications in society and describing what type of data is collected and how it is used.
