[ background music ]>>Narrator: So, when you
think of agriculture, what is the first thing
that comes into mind?>>Female 1: Farming.>>Female 2: Researching
in a lab.>>Female 3: Developing
new food products.>>Narrator: The interesting
part is that agriculture is a combination of all
three of these areas.>>Female 1: And even more.>>Remi Ojo: Hey! You must
be my new lab partner.>>Shireen Dhir: Yeah.
My name is Shireen Dhir. I’m actually a
graduating senior here and I’’m majoring in Applied
Biotechnology and with
a plant sciences emphasis. What about you?>>Remi: I am Remi Ojo.
I’m also a senior and I’m a Biological Sciences major. So it’s cool that we’re
both in the College of Ag. I haven’t really met that many
students in our college.>>Shireen: I agree.>>Remi: So have you ever
done research at UGA to kind of get your foot
in the door in Biotech?>>Shireen: Yes, absolutely. As a young scientist,
I’ve been able to work on many different projects such
as benzoyl research, biofuel production and
restoration of valuable crops. And I think the most fascinating
part of research is sharing and presenting it
within the community. I really think that it
always is enlightening to see other scientist come together
and share their ideas. What about you? What made you choose
your field of study?>>Remi: Well, I chose
Biological Sciences because I knew I’d be exposed to
a broad scope of biology and I knew I’d be able
to do research in a variety of
different fields. So after I took interesting
biology classes, it was really cool to get in
the lab and kind of see those concepts brought to life and
it kind of made difficult
concepts much easier. So how have you benefitted
from doing research?>>Shireen: Well, I think
the fact of working in a close-knit community in the
College of Agriculture it’s really allowed me to
foster relationships within the laboratory and have a
mentor/mentee relationship outside the lab as well. I think the research opportunities
are almost endless here. What are your experiences
with research?>>Remi: I think what
you mentioned about the close relationships with
faculty is really important; people kind of
underestimate those. And research also encourages
critical thinking and investigation which you
can actually take back to the classroom and it’s
really helpful in those upper level
science courses.>>Shireen: You really seem to
be passionate about research. Have you ever been able
to present your work?>>Remi: I actually have. UGA has a lot of different
opportunities within specific colleges to
present your research. You gain a lot of
confidence doing that; you even get to know about
career opportunities involving research. Once you take advantage of
undergraduate research here, you can maybe even do summer
programs in cool cities that you never thought
you’d live in or get your findings published
in a scientific journal. So those are really
interesting opportunities.>>Shireen: Yeah,
I absolutely agree. I think one of the benefits of
going to a large institution is that you can name almost any
field you are interested in and get involved
in no time! [ background music ]>>Deena Hussein: Hey everyone. My name is Deena Hussein and I’m an Entomology and
Biological Sciences student here at the
College of Ag at UGA. Now if I were to ask you
to define entomology, would you be able
to answer me? Well, for those who might or
might not know or have an idea of what it is, entomology
is the study of insects. Can you tell me what
defines an insect? Well, for those that
do know, good for you. For those that don’t,
an insect is an organism that has 3 body parts – a head,
a thorax and an abdomen – and also has 6 legs, in other
words, 3 pairs of legs. There are also those
that have either 4 wings like butterflies; 2 wings like house flies,
pesky flies; or zero wings like
ants and termites unless they’re the
reproductive female or male. Now, a lot of people tend
to have a negative feedback on insects and it’s majorly
due to the media. You have psycho-horror films; you also have these negative
connotations associated with them all the time. What people might or might
not know is that insects are major pollinators or
natural decomposers; when they do that, they
save us a lot of money. Now here to help me with
these negative attitudes is my friend Rosie. Rosie here is a Chilean
Rose-haired tarantula and actually the most
docile tarantula ever, well in the whole
entire world actually. A lot of people might think “Oh tarantula,
they might be poisonous. They’re going to bite.
They’re so dangerous.” But, like I said before,
they are very docile. The thing about Rosie, the only
danger she might do to you is that she would release
urticating hairs from her abdomen and those really
just feel like itchiness, kind of like fiberglass
if you were to touch it. Aside from that,
if they do bite – which rarely happens – it feels less painful
than a bee sting. If I made you interested
in insects today, there are more careers
that you can look into. Go online and type in
“Careers in Entomology” and you will have a whole
list that you can look into. And if you have any questions,
I’m pretty sure that all the faculty and staff here at the
Entomology Department at UGA would be more than
willing to help you out. [ background music ]>>Breeanna Williams: Ever since
I was a young child, I’ve always had a
passion for food. My mom is one of the
best cooks I know. She made it a priority to get
me involved in the kitchen with preparing meals for
my family and friends. When I got to middle school,
I also realized I was pretty good at the sciences
such as Biology and Chemistry. So I decided to marry my love for food and
my passion for science and that is how I ended
up at Food Science. Now, with that being said, let me show you one of
my favorite experiments. Food Science is the
application of science, technology, and engineering as
it relates to food materials, ingredients, and
their food products. Have you ever wondered how gummy
worms or gummy bears are made? Well if so, today is your lucky
day because we will be doing an experiment called
“Alginate Worms” where I can teach
you all about it. Let’s get started. The materials that you will
need for this experiment are a pipette, food coloring –
I have red but you can feel free to use any color
you would like – deionized water, sodium
alginate, calcium chloride, and sodium chloride more
commonly known as table salt. It is very easy to prepare the
solutions that I have here. All you need to do is take
2 grams of sodium alginate and mix well into 100
milliliters of deionized water. Follow the same
procedures for the calcium chloride and
sodium chloride using 2 grams of calcium chloride
added to 100 milliliters
of deionized water and 2 grams of sodium chloride
added to 100 milliliters
of deionized water. Using your pipette, pipette
a thin stream of sodium alginate into the calcium
chloride solution. Just like so. Set it aside and we’ll come back
to check on it in a minute. Using your pipette again, add a
thin stream of sodium alginate to your sodium
chloride solution. We’ll wait a couple
of minutes or so and then come back
to see what we have. If done correctly,
you should see gummy worms in your calcium chloride
solution just like so. You can squeeze them and
feel them just to see what the texture is like and if they
resemble any kind of gummy worms or gummy bears that
you’ve eaten before. In your sodium chloride
solution, however, you shouldn’t have
any gummy worms. Does anyone know
why this happens? Well, I’ll give you a
brief chemistry explanation to explain this to you. Calcium is a divalent ion
meaning that it can form 2 bonds with sodium in
the sodium alginate. This is why you have a
rigid gummy worm forming. However, sodium chloride
is a monovalent ion meaning that it can only form
1 bond with sodium alginate and not 2 like the
calcium chloride. Another helpful tip to make
this experiment go even better is to prepare you calcium
chloride solution in advance. This allows the calcium ions
to sit for a while and form even stronger bonds so that you will
have more rigid gummy worms. So the next time that you’re
at the grocery store, check out the ingredients label
of some of your favorite items. You never know, they
may contain alginate. I’m sure you all
are wondering “Can you eat this?” Of course you can. That’s one of the perks of
being a food scientist; you get to taste
your experiments; not all of them
but just some. And in this case, I’ll do you a
favor and try it for you. Mmm, very good. [ background music ] (c) 2013 University of Georgia
