Story and the Art of Story Telling

If you read various leadership articles, you are likely to have found a number of items related to the “Art of Story Telling.” From a leadership perspective, the idea behind this is that people are more in tuned to messages conveyed via a story. If you want to provide a lesson or a concept – you can put it in a story, people will pay attention, and are more likely to retain the information and get what you are trying to convey.

But there is more to “Story.”  Story throughout all of history has been used to convey – historical events, to entertain, to perpetuate culture, to convey cultural morality, and to pass on family. In general – a culture is defined by its stories. If you think about the stories that are traditionally studied in school – Aesop’s Fables, Greek Myths, and Homer’s Iliad and Odyssey. You can see how story has been used.

There are religious stories – the Old Testament Bible stories – Daniel in the Lion’s Den, Jonah and the Whale, and the Garden of Eden – as well as the New Testament Parables. In Native American culture – there are the Mother Earth stories. And, you can even follow certain themes throughout all cultures – there are common flood stories, and there is always a creation story.

Some stories have been preserved – the Bible, the Qur’an, and many epic poems (Beowulf, Gilgamesh, King Arthur, and others). But, many stories and possibly the most important ones are not usually written. These are the stories that hold families and/or clans together. The tales of how we as individuals are molded and taught. These stories are unique to the personal histories of each family.

For the last several years, my husband and I have noticed that our Society has lost the art of story telling – beyond the “Big Screen” and the television. Children don’t hear Mother Goose, Aesop’s Fables, or the traditional Bible stories unless a special effort is made to convey these through a lesson plan at school or Sunday School. We have seen that when the stories of the overall culture – the cultural fabric or quilt have disappeared – the quicker the disappearance of the family stories particularly the ones told from generation to generation. And, these are even more likely not to have been recorded.

I suppose that this is a result of losing the extended family. In most cases, we don’t live down the street from Grandma anymore. Great Aunt Mary is in Arizona for the winter. Even brothers and sisters are removed by several states. Closely knit communities have seen the “kids” move to the cities because of they don’t want to farm or the mill has closed to get a job. We have lost the time around the kitchen table or the campfire where the stories flow. How did you get that scar on your knee? Why did we live in that particular house? How did Grandpa come to live in that town? Are being lost faster than your current cell phone goes out of date.

We are losing this trait so fast – that there are articles about it for leaders. There are courses in journal-ling. Our Society has to make an effort to revive something that has been a part of being human since language was invented. This is evidenced by the fact that Museums like the Smithsonian have programs where people come to put down their oral histories or a particular story about a topic or an event. We see organizations like the American Chemical Society collect particular personal stories about why they chose to be come chemists. These are efforts being made because we are losing a part of us. We are losing what brings us together and we can very possibly be losing ourselves. Our personal story is what makes us who we are, but it is the grounding, the enrichment of the stories of how our great grandparents, grandparents, parents, and families that really tell us so much more about why we are the way we are.

A fun way to look at Spring!

Now that spring is here – spring fever is here as well.  Part of spring fever means that everyone wants to get outside and do something.  Photography is a great way to get outside and explore.  With digital cameras readily available – we don’t necessarily think about how cameras work any more – we point and shoot.  But camera technology is built on fundamental physics and whether or not you are using a traditional film or digital camera the physics is much the same.  The only real difference is how the image is recorded and stored. 

Light still passes through a hole and is projected on the recording surface.  Lenses are used to help focus the light onto our specific medium.  To help study the concepts of physics used in cameras – building a pinhole camera out of simple materials that you can find in your home is a wonderful activity.  Depending upon how complex you want to get – you can even make a working 35 mm camera out of a match box.  Here is a link to 23 different pinhole cameras that you can build at home.

 

Exploring Weather and Other Fluids

It is spring time in Oklahoma – so that means weather (severe weather) is just around the corner. And, it also means some really cool science that can be done to explore concepts like Archimedes’ Principle, Bernoulli’s equations and principles, and Pascal’s Law. Here are few links to keep you busy:

Here is a quick weather book of experiments

One for Archimedes’ Principle

And another for Pascal’s Law

Time to Heat Things Up

The Polar Vortex has been in the news lately and many of you have experienced some very cold temperatures.  But, just as the weather is warming; we can do a bit of hands-on science to look at the properties of heat.  Thus, we can heat things up a bit!

On Jan. 13, 1864, Wilhelm Wien a German Physicist who received the 1911 Nobel Prize in Physics was born. His work on the theoretical nature of heat allowed Max Planck to resolve the problem of radiation in thermal equilibrium and allowed for the development of techniques to measure high temperatures.  This makes it a perfect week to focus on “heating” things up a bit.

Heat can be transferred three ways: conduction, convection and radiation. Here are a few resources to help you explore the heat transfer.

From the University of Wisconsin – Here is an animated activity.

Science Games from Science Kids

From NeoK12 – Heat Transfer Games, Activities and Lessons

And finally from Discovery Education and Siemens Science Day – An Downloadable Experiment.

Have fun exploring how things heat up or cool down as the case may be.

Making Butter is all about Physics

The author of “CookWise” and “BakeWise” writes about the science behind various aspects of cooking and/or baking.  For some food items, its all about the physics.  For biscuits, it is about the steam generation.  For butter, it is all about the agitation and breaking of the suspension.

I have recently started looking into the physics of making butter – and while there are great hands-on science activities that relate to making butter – there is not really a good explanation of what is happening on a microscopic level.  (Here is a very good making butter hands-on activity from the Scientific American) But even this experiment doesn’t really get down to the basic science of what is happening.  One of the Dairy Science pages comes out and says “exactly how churning works is unknown”.

So, while there is no definitive reference for exactly what is happening, here are a couple of aspects of the overall process:

1) Whole milk – whether from goats, cows, sheep or other mammal – is a complex mixture of water, proteins and fats. In addition, the mother is also providing other essential items including vitamins, minerals and enzymes.  (You can go to the Milk Composition Website to learn more.)

2) Milk that you purchase in today’s grocery stores have been pasteurized and homogenized. The pasteurization process requires the heating of the milk to kill the “bad” bacteria, i.e. those bacteria that cause illness in humans.  Homogenization is a physical process, by which the larger molecules, primarily fats, are broken down to allow them to remain in suspension.  If you can purchase milk from a local dairy, you may be able to find non-homogenized milk. Non-homogenized milk will separate into layers, i.e. a cream layer and a milk layer.  (This is a physical separation using gravity.  A commercial dairy uses a centrifuge to perform this separation and provides a milk with a consistent fat content. It is still a physical process based upon the density of the material.)

3) Milk can be considered a colloidal mixture.  A colloidal mixture is a fluid in which “particles” are suspended in a liquid, or dispersed throughout.  You can think of milk as being a mixture of water, butter fat particles, protein particles, etc. suspended and floating around in the container.  It is essentially, a liquid with very small solid particles floating in suspension.  This is a bit different than an emulsion.  An emulsion refers to two separate liquids, with droplets of one liquid floating in another liquid, for example oil and vinegar salad dressing.

So, what is happening when we make butter?

First, making butter requires “churning” or mixing of the cream. We have started with a physical separation of the butter fat into the cream layer and now have begun agitating it.  As the churning progresses, air is mixed with the cream to form a foam, i.e. air is trapped among the butter fat particles forming a stable suspension.  As the churning process continues, the “whipped cream foam” falls, i.e. the foam is no longer stable, because the butter fat particles have now begun to aggregate into larger particles and are no longer able to form the foam lattice.  The churning continues until large clumps of butter can be seen and collected using a strainer.

The entire process appears to be based on aggregation of the the butter fat particles by increasing the amount of individual interactions between the particles through physical agitation.  It is apparent that the collisions between butter fat particles under these conditions is inelastic, hence the aggregation of the individual butter fat particles.

Hopefully, this brief explanation will allow you and your aspiring kitchen helpers – to play with physics and enjoy the tasty result!

The Holiday’s are Almost Over – Back to Normal?

On Monday, January 8; most of the United States will return to a “normal” work/school week. For us the holidays are over and we must return to that hectic existence we have built for ourselves.  Social and sport groups are resuming full swing, and just look at that in box for the email.  (It is enough to make your head spin.) 

For homeschoolers, we have a bit of a choice.  We can return to that hectic existence on a more reasonable pace.  We can choose to focus a bit, put a bit more quality into our curriculum and not have to throw ourselves headlong back into the U.S. interstate speed culture.

So, from a science perspective; why not take a bit of time to reflect just how fast science can change our perspective and fundamentally our lives.  On January 8, 1642 Galileo Galilei died.  On the same date in 1980, John William Mauchly (with Presper Eckert – the co-inventor of the ENIAC – Electron Numerical Integrator and Computer – the first general purpose computer) died. And, in 1997 – Melvin Calvin died, a Nobel Prize winning chemist and discoverer for the Calvin Cycle, carbon fixing in plants.

All three of these individuals radically changed our lives.  So, here are some suggestions based on these three individuals:

  • Make a telescope (There are several internet how to’s – youtube videos, plans and kits available.  Because, every home has a different set of materials, I am not posting a particular one as it may not fit your specific resources.)
  • Visit the ENIAC Museum Online
  • Learn more about the Calvin Cycle from National Geographic Education

A gift that continues to enhance a life

As the holiday season is in full swing – many of us are looking for that special something to give.  For me it has always been books.  I love to read.

Reading enhances many aspects of life – it opens doors, it expands curiosity, it activates the imagination, it stimulates thinking, and it promotes communication.  For many of us – reading is second nature – but for some – it is a luxury.  For example in a recent interview with David Risher on NPR he tells of an experience in Ecuador where the library was locked and children did not have access to the books.  This experience has inspired him to work with tools that are available in developing countries to get books into the hands of children.  While it may seem counter intuitive – eReaders and cell phones – seem to be a great solution.

There is a meme going around on Facebook – showing a child sitting on Santa’s lap saying that the toys wanted for Christmas included space travel, rocket ships, jungles, animals, etc.  Santa gives him a library card.  

As a child we moved all the time (I am from a military family) – one of the first places I went in our new hometown was the library as it opened the doors to the community and that is where the books were.  My home is filled with books (my husband made the mistake when we first were married saying he would never question my expenditures on books – not sure he still shares that sentiment as we now have more books than many small town libraries).  

So the gift of reading to me is invaluable – reading to children is a way of spreading that gift.  Books allow people to explore without every leaving the comfort of their favorite chair.  We have gotten away from reading due to the television and video on demand – but reading, at least to me, is much more expanding and thought provoking.  

Reading teaches, reading shares life stories, reading opens opportunities, and creates visions.

So – this holiday season – or anytime – give the gift that expands a person’s world – a book.

For you science lovers – here is a link to the podcast from the AAAS describing this year’s science book recommendations for young readers. My particular favorite is Rosie Revere, Engineer.

 

 

It is December already…..

You are probably in the throws of a busy holiday week – family, food, traditions, football, fun.  And – on Monday you will think – I can’t believe that it is December already.

If you are like most people – you try not to decorate for Christmas until after Thanksgiving.  If that is the case – then you can do some fun science to help decorate around the house –

Have you thought of a “Chemist” Tree?  You can do pretzel and gumdrop molecules.  Or do paper chromatography to create beautiful ornaments for the tree.

You can do some crystallization experiments – growing sugar crystals or growing Epsom salt crystals (NOTE: Parental supervision will be required.)  You can also make a solution of Epsom salt in water and “paint” on heavy card stock and let it dry – to form crystals on the paper – this is particularly good on red card stock as you make white crystal images.  (NOTE: you should not let children get the Epsom salt solution in eyes or drink the solution.  Goggles are recommended.)

Have Fun.

Remembering and honoring

On the eleventh hour, of the eleventh day of the eleventh month – World War I came to an end.  This day is celebrated today as Veteran’s day in the United States.  A Monday in November is set aside as a federal holiday to allow communities to honor those who have served and those who serve.

As homeschool families, this day provides an opportunity to integrate our various curriculum activities with what is happening in the community.  There is an opportunity to explore history, and conduct interviews with individuals who witnessed events first hand.  There is an opportunity to participate in community activities such as parades, concerts, flag raising and lowering ceremonies, and visiting cemeteries.

While we think primarily of history, writing, poetry, and literature for activities related to Veteran’s day – there are some science related topics that can be incorporated as well.

Weather influences history – a wind sock (you can find several craft ideas for making a wind sock) may be an excellent way to show a bit of patriotism as well as incorporating how weather may impact world events.

Technology – while it may have been developed for defense – there are a number of peace time applications of various technologies.  Infrared detection is a great example.  The infrared cameras can see flaws in metals, and help detect with early detection of equipment failures.  Medicine and medical treatments have been influenced by events on the battlefield.  Even how goods are transported to your local big box store – is the result of solving a problem during the Berlin Airlift.

Science can be reflected in a number of ways as you celebrate this holiday.  You can see it right in front of you in the form of medical devices, architecture, and the overall health of some of those participating in the parade.  Just take a quick second to recognize it.

But, don’t forget to thank that veteran for his/her service.  It is their dedication to our values that allow us to have the freedoms we hold dear.
