Edutainment in the Magic Tower : Environmental awareness as a lifelong learning process
The type and nature of the environmental p
roblems we are facing currently
require an adaptive
environmental education that is a lifelong learning process rather th
an a matter of formal schooling.
The
Magic Tower
Science
Career Orientation Center and Museum at the E
szterházy Ká
roly University Eger
has been committed s
ince its foundation to promote
lif
elong learning, and establish
,
in general
,
an
atypical, informal
,
and non
-
formal science
educational culture in Nor
thern Hungary.
One of the target
areas of the Tower are the current environmental issues faced by the humanity.
In the recent years, the
Tower has launched s
everal
self
-
paced
and inquiry
-
based science programs that intended to raise
motivation towards envi
ronmental sciences, and to create responsible individuals capable to identify
environmental issues, engage in problem solving, and take efficient action.
These programs
were
aimed at
audiences of different age and education level, ranging from preschool ch
il
dren, through secondary
school students
, to
parents and
non
-
specialized researchers.
In the present communication, we summarize
some of these
activities, along with their achievements
A diffusion-induced transition in the phase separation of binary fluid mixtures subjected to a temperature ramp
Demixing of binary fluids subjected to slow temperature ramps shows repeated
waves of nucleation which arise as a consequence of the competition between
generation of supersaturation by the temperature ramp and relaxation of
supersaturation by diffusive transport and flow. Here, we use an
advection-reaction-diffusion model to study the oscillations in the weak- and
strong-diffusion regime. There is a sharp transition between the two regimes,
which can only be understood based on the probability distribution function of
the composition rather than in terms of the average composition. We argue that
this transition might be responsible for some yet unclear features of
experiments, like the appearance of secondary oscillations and bimodal droplet
size distributions.Comment: 6 pages, 3 color figure
