Stella

We employ STELLA modelling in combination with investigative exercises and experiments.  The modelling helps students develop hypotheses, explore predictions, summarize experimental results, and extend their results to novel scenarios.  STELLA provides the flexibility to allow students to model a variety of experimental systems and the power to provide for meaningful outcomes that relate to specific biological content. We are developing and implementing modelling exercises to bridge the rift between biological content and student experiments. Many of the exercises will adapt a computer simulation software package that lets students construct dynamic simulation models for their particular experiments. The STELLA software allows students to develop and parameterize pool and flux models to explore model dynamics, and to make quantitative predictions of experimental results. The modelling exercises will not only help students create more specific hypotheses, but they will also provide a context to evaluate their experimental results.

1) Download STELLA Software

2) Open STELLA

3) Choose one of the sample. Example 'Nitrogen Cycle'

4)  Click 'conduct experiment' to run the experiment

5) Click 'play' button to start the experiment for the first run

6) Try to change the value of the manipulated variable to see the different .

7) Sample Nitrogen Cycle ( Core Model Structure)
