A battery powered UV light or a lantern placed behind
a hanging sheet can be fun portable tool for
night-time insect studies.

Another good source of internationally portable
science is Vikki Cobb’s(?) book, Science You Can Eat.
It’s pitched at kids but does a great job presenting
essential chemical and biochemical concepts in a
kitchen context. I think many of the lessons could be
adapted to work anywhere folks eat carbohydrates,
protein or fats.

A favorite, highly portable biology lesson is the
build-tree activity from the environmental education
repertoire. It’s adaptable to different age levels and
group sizes. In the activity students role-play parts
of the tree xylem, phloem, cambium, roots, branches,
leaves, (chloroplasts if you want greater detail) and
bark. They read the functional description of the part
of the tree they represent off an index card (not
essential) and pantomime its function while making an
appropriate sound. One by one parts are added to the
tree. For a finale the parts sound off together. Refer
to Joseph Cornell’s books for many other environmental
science activities requiring little or no equipment.
Most are suitable for young students but some are
adaptable to older groups.
