What is modelling?
The British Computer Society: IT Glossary for Schools
National Curriculum ICT
Programme of study
How to use ICT to test predictions and discover patterns and relationships, by exploring, evaluating and developing models and changing their rules and values (ICT NC KS3 2c)
Level4: They use ICT-based models and simulations to explore patterns and relationships, and make predictions about the consequences of their decisions
Level5: They explore the effects of changing the variables in an ICT-based model
Level 6: They use ICT-based models to make predictions and vary the rules within the models
Level7: They design ICT-based models and procedures with variables to meet particular needs
Teaching objectives for Years 7, 8 and 9
Based on the National Curriculum programme of study for ICT at Key Stage 3, for example, for Year 9:
What are you trying to model?
Sample scenario …
You make a fresh cup of coffee in the staffroom at break-time, using boiling water from the kettle. How long will it take before it is drinkable?Try to set up a spreadsheet to model the cooling of the coffee.
Some examples might be:
Setting up a spreadsheet
Information about the sheet
Input values (parameters)
=B11+1 then copy down
Table of data
Reviewing the model
Testing the model
Hand-held datalogging equipment can be used to collect live data
Testing the model
Can the temperature of the coffee fall below room temperature?
How might you adjust the model to make sure this cannot happen?
