This question is both broad and deep!
Scientists help us in many areas of our daily
lives, such as health and medicine, materials,
new technologies, and offering explanations of
how things came to be. Health and medicine are
important because they contribute to higher
standards of living; this helps people live
longer and survive diseases that could otherwise
be deadly or seriously debilitating. Materials
are important aspects of our daily lives:
material technologies are found in the personal
care products we use, like shampoos, creams, or
soaps. Other examples of materials we often use
are plastics, adhesives (tapes, glues), paints,
fabrics. Furthermore, there are exciting uses
for nanomaterials! And what would the world be
without technologies such as the computer, cell
phone, or microwave? Scientists are also
interested in explaining how things work. All of
these great advancements and technologies in
medicine, materials, and electronics would be
hard to come by without a decent understanding
of how cells, chemicals, particles, and so on
function and behave!
Scientists find out things that were not
known before. This is useful in several ways:
first, engineers can take what scientists learn
and use it to build things, and second, science
is interesting in its own right. It's learning
about the world.
I like your question. I read a good answer
to your question in a newspaper about physics.
The newspaper says scientists are helpful to us
because they do useful work, like carpenters
and cooks and doctors and bus drivers.
Scientists do work that helps figure out how to
make things like new iPads and new medicines
that are fun and useful to us.
Keep asking questions!
Scientists are helpful to all of us. They
create new technologies to improve our health
and well being. For example, a scientist
discovered plastics to create containers. We use
plastics in medical situations to keep items
sterile (meaning very clean) and single-use so
that we don't transfer diseases from one person
to another. A different scientist created
helpful drugs to rid bacterial diseases, so when
people come down with a cold caused by bacteria,
we can take medicines to get rid of those bad
bacteria. Yet another scientist discovered how
to vaccinate us so that we don't catch some
diseases at all. You don't have to train as a
scientist to be a scientist though - you just
have to want to know how things work.
