Evaluating models My model was of the _______________
A major advantage of models is that they allow us to visualise concepts which are too small
to be seen by the naked eye, for example, chemical bonds or cells.
In my model, people can visualise…………so they understand ……… without needing a
microscope.
Models are also useful as they can communicate scientific concepts to the general public by
using things they are familiar with.
My model is………….(colourful/large/funny/entertaining etc), so people would feel drawn
to it and therefore want to learn about……….
Finally, models are useful to demonstrate processes that occur too quickly or too slowly to
see in nature. For example, the model could be used to model the ……….. process within
the body.
A disadvantage of models, is that they can reinforce misconceptions. For example, someone
may think that ……………….that I used in my model, or the same size, when in reality they
are not.
Another disadvantage is that they are not always to scale, and may use approximations, so
people may get confused about how big …………are, compared to others.
Finally, models often do not have enough detail to accurately demonstrate a concept. For
example, my model does not show what is happening ……………, even though, in
reality,…………….
Overall, while models have limitations, they are very useful at communicating the ‘big
picture’ to someone, so that they can learn overall concepts.
