Hello Teachers
I am excited for you to learn new ways of looking at STEM.
Let me tell you a bit about myself. I am an engineer with
masters in electronic engineering, Mathematics and working on an MBA. I am also
a literature enthusiast who has taken classes at ASU. I had to consciously
drive my brain to the arts or science side depending on different phases of my
life. In high school, I was encouraged by my English teacher to write essays.
In undergrad college dubbed as Boring Institute of Test Series, I read classics
during holidays or breaks. I took part in creative writing competitions and
collaborative painting during breaks. I had to wait for the right personal time
to devote myself t reading and writing. When I got some time to write, this is
what it was all about.
Difference between a creeper and a climber
This is one of the earliest questions that I remember from
Elementary school. It wasn’t obvious then, but now I can relate them with
creepers on ground and climbers on wall.
Germination experiment is such a mnemonic like the half
empty or full glass. Either side of the glass you take, in the middle is where
you need to be for the seed to germinate.
The other day my daughter asked me what would happen if you
put too much salt in water. I told her about saturated solution. Better yet, I
told her that she could do the experiment the next day. Her science vocabulary
is increasing. She is 8 now.
In high school my dad would ask us to draw an outline of our
footprint, so he could buy us shoes on his way from work. Recently at Saguaro
national park we bought a nature lovers guide which showed different animals
footprints. By looking at the tracks on the ground you could tell which animal
was there before you. These are the kind of things that you become aware of
during birdwatching. Is birdwatching art or science. The science part of it is
ornithology. The other day when I read about dogs helping in archaeology, I
asked my daughter if she knew what it meant. She said its something science
because of the ‘logy’. A while ago she told me about her interest in rocks due
to a beautiful geode from her ‘Little Passports’ kit from my friend. From there
we learnt about petrology.
From all the examples, I have shown you so far, I want you
to know that your class will come alive in the future many time in many lives.
How to STEP into STEM
When I started thinking about sharing what the fun part of
STEM for me is… I always went back to these famous examples of Archimedes
crying Eureka in the streets, pencillin serendipity and so on. In each of
these, I felt we could role play those discoveries. The research can be boiled
down to ‘fact cards’ when students ask the right questions. You guide them to
the questions. Somehow I got started with Pasteur and found that he had saved
so many species with the same technique of inoculation. again and again. I also
want to show a little bit of my continuous learning experience.
How kids learn
When I asked my kid about how she chose to do the chicken
soup, the answer came to be that it was for kids.

If you cant teach something to a six year old,
then you don’t understand it yourself. – Attributed to many many
Wired 5 levels of difficulty of
explaining a concept – This could be an interactive activity where the teachers
write how they would explain the concept to different grades. In my Math class,
our teacher would give us one tough, cool question which was an achievement if
we could crack it. After the exam we would all convene to figure f we got that
right. It is said that kids should be asked questions that they cannot solve
atleast 30% of the time. So it should not always be about kids getting it all.
Let them have some questions and some inconvenience of not figuring out so they
can refer extra material and dive deeper.

Keying into the fact that Feynman said
“What I cannot create, I do not understand”
“Know how to solve every problem that has been solved” –
Richard Feynman
If kids can recreate in their minds, the problems and how
the solutions came by, they will have a framework to recognize the way forward.
If I were Pasteur and if I knew what he knew at the onset of
the problem, how would the process look for me? The STEP process jumps from
problem to solution. But that step could mean many leaps and many gaps. In Pasteur’s
case it took him a year to find out what was happening. When he spoke to the
beer maker, he asked for good and bad samples.
After seeing this book, I narrated the story to my daughter
to see if I could elicit some of the responses I was hoping for. Seeing that
the two samples were different. With some prompting, I was able to get the
answer from my daughter that in the end, he would know if the beer was right by
looking under the microscope and had the good round yeast.
This scenario can be played with kids too where they act out
what they have learned. Kids are very good at detecting patterns. I feel
jealous of Gauss that he was able do the addition of 1 to 100 so quickly
because he saw the pattern.
The other kind of roleplay is using kits Like Blue’s the
Clue with built in hypothesis instructions and guidelines for the ‘Design and
Conduct’ lab and Observe, Record, Report lab.

If we emphasise on what tools are consistently being used in
these discoveries, then we will provide kids with toolsets. While some of the
toolsets are analytical, the ones that have helped the scientists are courage,
tenacity and curiosity.
The jump from the S to T has more steps.
Bigger problems can be broken into smaller problems with the
same loop repeating.
To maintain curiosity and relevance, assign a day to a child
to bring in a science fact or event or any question that happened. The other
day my kid asked me if birds have ears. I never thought about that. When I was
in my sixth grade, I had a question as to why I could still hear even though I
closed my ears. I now know that we hear through bone conduction too.
Current coronavirus situation is a great tool for scientific
process explanation.
Books like Pasteur and pasteurization make science fun. Lenny
Cyrus, School Virus is another great book on blood brain barrier and
anthropomorphization of different organisms.
When possible I try to catch up with science fairs both the
school ones where I take my kids. Recently I took my kid to catch up with a CES
presentation in Phoenix. There we met the inventor of a Robotic machine. He
told that his inspiration was the “plenty of room at the bottom” speech
referring to nanoparticles.

After this, I got interested in the reverse of what if we
had to make something large. If we had to weigh it, the precision. You can lift
it but you cant weight it? Lever principle
If Sisyphus was smart he would use a counterbalance?

Even know when I read science journals that say that some 90
year old theory has now been proved, it gives me goose bumps that they had to
wait for sophisticated instrumentation this long, but also that someone could
precede proof that long ago. Excellent theorists. There is an interplay of
technology making new discoveries possible.

Lets make those Theorists that will power the future
technologists.
Getting to the source of inspiration of the giants before us
will lead us into the STEM.
