modeling and simulation

• Technology
• Secondary Education

What is a simulation and why are they used?

1. A simulation is a giant model in motion for a test.
2. A simulation uses one or more models to imitate how those models might function in a real life situation.
3. A simulation tests a hypothesis with 100% accuracy.
4. A simulation is the mathematical formula

Models can be helpful in scientific investigations because

1. may not be possible to work with the real thing.
2. they can be smaller and more manageable than the real thing.
3. they can be safer to work with than the real thing.
4. all of the above

Which comes first, the model or the simulation?

1. The two are unrelated and can be created in any order.
2. They are created at the same time because they are pretty much the same thing.
3. The model is created first because a simulation needs models to run.
4. Simulation is created first

Modelling and Simulations

Why is visualization of data important?

Advantages of modelling and simulation

• Can be safer and cheaper than the real world.
  
• Able to test a product or system works before building it.
  
• Can use it to find unexpected problems.
  
• Able to explore ‘what if…’ questions.
  
• Can speed things up or slow them down to see changes over long or short periods of time.
  

Disadvantages of modelling and simulation

• Mistakes may be made in the programming or rules of the simulation or model.
  
• The cost of a simulation model can be high.
  
• The cost of running several different simulations may be high.
  
• Time may be needed to make sense of the results.
  
• People’s reactions to the model or simulation might not be realistic or reliable.
  

What are faulty and hidden assumptions?

Too many characteristics are included the model may become large and difficult to manipulate.

Example: An engineer designing a metal bridge assumes that color of the bridge is not relevant to stability. however color of the bridge influence temperature and so on. This is the hidden assumptions.

What are some problems of simplifying reality?
