Quantitative model on economical developmentsThis quantitative model compares the average income and wealth of the people that earn above the average or those who lend money with those below average or those who borrow money. It includes interest rates initial inequality savings quota money creation (the possibility of banks to lend more than they hold) productivityThe model allows to understand the basic developments and to try scenarios on degrowth, by trying a negative productivity re-coupling of financial and real economy by negative money creation use or harm of interest rates decoupled from productivity In order to explore some scenarios I have saved with the model got the the factor "discrepancy" and l ...»

A model explaining some of the obstacles of the transformation towards electric vehicles (EVs) This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the development of the uses of gasoline cars and electric vehicles (EVs) using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER. When we continue to ask we should discover the balancing feedback loops of diminishing resources and the reinforcing feedback loops o ...»

Just a small model as a preparation to model with children the question how watching TV and energy consumption are connected. I recommend to start with the two factors watching TV and happiness and then continue to ask what it does mean with regard of energy ... and finally how this is connected with happiness. Probably the children will come up with a completely and yet very interesting model :-)

what do we need energy for? ... an unfinished model for inspiration for modeling with children.

A model exploring the challenge of less pollution This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the measures for a healthier environment using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER. It starts with the different forms of pollution and then continues to reflect on their underlying reasons. Interestingly it turns out that the underlying reasons are rather psychological.  The Insight Matrices  ...»

A model explaining the common reasons for wars on earth This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks seemingly naively for the reasons for wars in the world using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER. When we continue to ask what leads to it and what can be done we will see the importance of some economical and some psychological factors. Pupils should be at least 10 years old. Time10 years  ...»

A model explaining the basic logic of money flows This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the origin of the money in our pockets (using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER). When we continue to ask where it comes from we will finally realize the closed loops the flow of money forms, even if we include the creation of (fiat) money by central banks.  As a very basic model it is possi ...»

A model explaining the basic loops of agriculture This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the sustainability of farming using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER. When we continue to ask where our vegetables depend on we will finally realize the need to close loops and to change our hapits.  As a very basic model it is possible to model this topic with six years old children provid ...»
