Despite the chilly weather, my husband and I strolled the sidewalks of Atlanta on Saturday for the final day of the Atlanta Science Festival, admiring the blooming cherry trees and the crowds of excited children. The organizers of the event did an excellent job providing interesting booths featuring science of all kinds and promoting the event to the multitude of families who attended, and at no charge as well. I was very impressed with how well the event got kids interested in science. We skipped most of the booths because the sheer numbers of children crowding around them, and we wanted the kids to have priority.
I would love
to attend an event like this in Orlando or the Space Coast. I’m amazed that an
equivalent doesn’t exist even at a smaller level. I attempted to organize a
much smaller version of this kind of event two years ago, but I didn’t have the
resources. It would be fantastic if an existing educational or outreach entity
organized a mass science or space festival for families and the community in
our area.
My favorite
booth was the demonstration on cosmic rays by Georgia Tech. They featured a
small cosmic ray detector called a spark chamber that uses photomultomultiplier
tubes to convert the high-energy cosmic radiation into electric charge. Sparks
illuminated the detection box every few seconds like lightning and just as
quick. I captured a video of a spark and took a screenshot. Cosmic rays impact
the surface of the Earth frequently at all times, and we don’t even notice
unless we purposely look for them.
That great
physics demo made up for the disappointing astronomy presentation at another
booth. The presenter resorted to deflecting questions and making stuff up when
he didn’t know the answer to questions he wasn’t prepared for. One thing we
learn as scientists and throughout life: it’s okay to admit you don’t know. I
would have far more respect for a man who had admitted not knowing because this
isn’t his field rather than letting pride get in the way.
I’ve just
volunteered to be a judge for my undergraduate university’s science and
engineering design showcase for the third year. It wasn’t too long ago that I
was on the other side of that uncomfortable situation, cramming last-minute
knowledge about my project and nervous about what the judges may ask. It's not always a fun experience to prepare for and go through.
As a
judge, I’ve gotten a new appreciation for the difficulty of presenting science
to anyone, let alone someone who may not have a science or technical background.
But I do have some tips for students who need to present information to an
audience. This is not an extensive list, but it's the top 7 that comes to my mind from college and high school science fair judging.
7 Tips for Presenters
1. Enjoy what
you’re talking about. If you’re not interested in the material you’re presenting,
don’t expect your audience to be interested, either. Years ago I attended a
talk by a former grad school classmate who looked absolutely bored and I
remember thinking that he must be miserable in his work. If you want your
audience to think that you’re doing something exciting and meaningful, then you
need to believe that yourself and beam those vibes to the world. Also, if you're excited, you'll naturally speak loudly and clearly for all to hear.
2. Take the
time to be there. If you can hang around your poster or hang out after your
talk to discuss your work further, it appears that you’re really invested in
what you’re doing. People may be interested in your work or may just want to be around you to get to know you better.
3. Start from
the beginning and work your way deeper. I’m an almost-PhD in physics with two
physics-related degrees, but I don’t remember every topic that I was taught in a
class I took a decade ago and I may need a refresher on what you’re talking
about. Take care not to give lip service to Step A then jump straight to Steps
X, Y, and Z, ignoring the in-between. Go in logical, methodical order, even if it means sacrificing some
details at the end.
4. What do you
want your audience to take away? Why should we care? We may only remember one sentence of what you
said. Say it at the start, repeat it at the end, and use much of the middle to
explain how you got there. I will not remember your 20 conclusions, but I may
remember your big conclusion if you present it well.
5. Know what
you’re talking about. If you’ve spent an entire year studying a subject, I’m
going to presume that you can answer basic questions about that subject. If you
know only about what’s on your poster or in your talk and you know none of the related
material that puts your research into context or perspective, then I’m going to
assume that someone else did your research and you only pushed a button or
assembled a spreadsheet. If you want to be seen as more than a mindless data
collector, then know your stuff.
6. It’s okay to
admit that you don’t know. Students don’t know the breath and depth of their
field. College students should know more than high school students and graduate
students should know better than undergrads, but not even experts in the field can
answer all of the questions or know everything. Most of the time I ask
questions, it’s not to test someone’s knowledge, it’s because I’m curious and
want to learn more. The student presenter may not be the best resource to
answer my questions and I respect a firm, “I don’t know. Good question.”Even better if you can help me to find the answer.
7. Keep
learning. A student who will take what
was learned in this project and apply it to whatever comes next, even if
totally unrelated, earns more respect in my book than a student who signed up
for this research to get credit and doesn’t really care. I never wanted to be a chemical engineer, it was just a temporary work experience, but I look fondly on my three months as a chemical engineer at NASA MSFC because it was really neat and eye-opening, even if I don't want to do that again. We can learn from any
situation and any experience if we choose to.
