Extract:
This article talks about the invention
of two teenagers, who presented its device on Intel International
Science and Engineering Fair created by the Society for Science and
the Public.
The aim of these teenager's invention
was to optimize the purpose of casts. Casts are intended to hold the
limb firmly in one position for a few weeks as the fractured bone
heals. But costly or painful problems can develop, especially if the
limb swells a lot after the cast has hardened into its final shape.
For this reason, they’ve developed a computer-controlled inflatable
bladder to fit between the limb and the cast. Electronics monitor the
pressure inside the bladder. As needed, they adjust how much air it
holds to keep the liner grip on the limb firm but comfortable.
Critical
appraisal: Teens and science
In
this article I've found out that there are many people who organize events and contests in order to encourage teenagers to let go their imagination and talent in the field of science. Furthermore, we should also highlight the number of teens that participated in the fair the article talks about, which is called Intel International
Science and Engineering Fair. This year, 1702 finalists from more than 70 different countries came to that event. I'm gladly surprised by these data, because that means that young people have concerns about science and come up with new and fresh ideas which may be put in practice in the future.
I'd also like to say that, in my opinion, big or useful inventions don't have to be something impressive always. What I'm trying to say is that when we think of inventions we always have in our minds the bulb, the plane or something like these. Nevertheless, inventions can be something as simple as the mop, which is a stick attatched to a cloth. Inventions are that kind of devices that makes you life easier. For these reason, although this girls' creation may not seem relevant, if it helps to optimize the casts, it will be worth it.
I'm really impressed by the discoveries of these teenagers, not because they are of great importance, but because of the effort and hope they have surely put in her research. Her example makes clear that you don't have to be an adult to investigate or to make a research on something that intrigues you. You just need to have interest and constancy.
It's great to know that there are teenagers like them in the world, because the future of this planet lies in our hands.
I believe teenagers like them is what our world needs, because future is just around the corner and we really need intelligent and working people in order to face it.

Glossary:
Bladder
A
flexible bag-like structure for holding gases or liquids.
Cast
A
shell made of plaster, fiberglass or other hard material that encases
a limb or large portion of the body, often to stabilize broken bones
as they heal.
Society
for Science and the Public (orSSP)
A non-profit
organization created in 1921 and based in Washington, D.C. Since its
founding, SSP has been not only promoting public engagement in
scientific research but also the public understanding of science. It
created and continues to run three renowned science competitions,
including the Intel International Science and Engineering Fair
(initially launched in 1950). SSP also publishes award-winning
journalism in Science
News
(launched in 1922) and Science
News for Students
(created in 2003). Those magazines also host a series of blogs
(including Eureka! Lab).
Sensor
A
device that picks up information on physical or chemical conditions —
such as temperature, barometric pressure, salinity, humidity, pH,
light intensity or radiation — and stores or broadcasts that
information. Scientists and engineers often rely on sensors to inform
them of conditions that may change over time or that exist far from
where a researcher can measure them directly.
Tissue
Any of the distinct types of material, comprised of cells, which make
up animals, plants or fungi. Cells within a tissue work as a unit to
perform a particular function in living organisms. Different organs
of the human body, for instance, often are made from many different
types of tissues. And brain tissue will be very different from bone
or heart tissue.
