Worm Moon

Tomorrow we’ll have the first Supermoon of the year – the Worm Moon!  Do you know where the name comes from?  Here’s a short story I wrote (meant to be told orally).  I hope you can share it with your children, or at least enjoy its message.

*****

Look up!  What do you notice?  Did you observe that the full moon is larger than usual?  We call it a Supermoon, and your eyes aren’t deceiving you… The moon IS larger than usual because it’s closer than usual, and that’s because the moon’s orbit around the Earth isn’t perfectly circular – it’s elliptical.

Every Supermoon has a special name, and today I want to tell you where this one’s name comes from.  Let’s go back five or even ten thousand years ago, to when the native people of this country lived in harmony with nature.  During Winter, the humans who lived between Lake Superior and New England in what is now the United States hunted, wore animal skins, made fires, and took shelter from the snow.  They waited patiently for Spring to come, but they didn’t have calendars like we do. Instead, they observed nature to know when the seasons were changing.

Every year, around this time, they noticed tiny, dark brown pellets on the cold, slowly-thawing ground.  These pellets – we call them castings – were a clue for them, a message from nature that warmer weather was ahead. When these castings appeared, so did something else: robins – grey birds with bright orange breast feathers.  The robins weren’t eating the castings, because castings is just a fancy word for poop! They were preying on the animals who left the castings. Can you guess which animals the birds were eating?

Yes, worms!  Earthworms! The appearance of worm castings told humans that warmer weather was on its way, because the ground was now soft enough for the worms to move through it.  The presence of worms also indicated that the land was almost ready for planting, since these animals do the important work of aerating the soil and their castings help plants absorb more nutrients. 

Earthworms came to signify the end of winter and the approach of the planting season, which meant fresh food and survival for another year.  And thus, this Supermoon became known as the Worm Moon.

Other human groups have given it different names, like Crow Moon, Crust Moon, and Sap Moon.  You can investigate the stories behind these names and let us know what you discover. But for now, when we look up at the Worm Moon, we can think back to those patient and resourceful people who didn’t need paper calendars, because they lived in harmony with the Earth.

Story of Chemistry: Part I

I wrote this story a while back for the Upper Elementary group I inherited that hadn’t been exposed to chemistry.  I never got around to writing Part II but if you take on that challenge, let me know!

*******

Pretty much all that we see or touch in our seemingly solid existence is made from an unimaginable number of tiny atoms, each a different type of element or building block. When you combine these atoms in different ways, they make up everything that we can see in the Universe.

Do you remember when we told the story of The Origin of the Universe? We talked about an enormous cloud of gases that swirled in Space. These particles started to come together as the Earth cooled. Some became solids, some turned into liquids, and some remained gases. The rain, the oceans, the rocks, and the air were all made from different combinations of elements, and later on, life also emerged from these same building blocks.

Humans have tried to understand elements since the dawn of recorded time. Copper, for example, has been used since at least 9000 BC. That’s more than 11,000 years ago! By the time of the Ancient Egyptians, around 5,000 years ago, seven metals had been discovered and were being used for everything from weapon-making to jewelry. The Egyptians had a strong connection between the metals, the cosmos, and their fertile land, and called this study Khem.

The ancient Chinese, around the same time period, thought that everything was made of five elements: water, wood, fire, earth, and metal. They used these ideas in their development of acupuncture. In India, they were also studying matter, and discovered how to use the color of fire to identify different types of metals.

When the Greeks conquered Egypt in 332BC, they became interested in the Egyptian theories of how matter was made. They turned the word Khem into Khemia , which became the Greek word for “Egypt.” Around that time, the Greek philosopher Aristotle decided that the building blocks of all matter should be called elements. According to him, there were five: earth, air, fire, water, and quintessence, which formed the heavens.

In the 7th century AD, Egypt was invaded by the Arabs, who added the prefix al- to Khemia. And thus, the science of alchemy was born. For centuries, Arab alchemists used what they knew about elements to try to discover a way to make a substance that would make humans immortal. They also wanted to turn ordinary metals – and other substances – into gold, the most valuable of metals.

When the Arabs invaded Spain, they brought their ideas of alchemy with them and kindled the curiosity of many scientific minds in the European continent. The search for a way to make gold, known as the “philosopher’s stone,” drove many scientists to try some very odd experiments indeed! A German alchemist, Hennig Brandt, tried boiling down urine, thinking he could find gold in the yellow liquid. What he discovered, quite by accident, was a new element: phosphorus!

Why was this so ground-breaking? Because phosphorus, rubbed the right way, would burst into fire (guide lights match). It went on to be used in the invention of matches. Brandt had proven, by accident, that substances commonly found in nature could be “turned” into something valuable. He hadn’t really turned urine into phosphorus; he’d just separated the phosphorus from all the other elements that combine to make urine.

Brandt’s discovery caused many alchemists to look around and wonder: What’s all of this made of? Have you ever wondered that, too? Think about air, for example. Humans have always felt air and they’ve seen its effects during hurricanes and tornadoes, but they never understood what it was.

In the late 1700’s, this all changed when an amateur British scientist named Joseph Priestly discovered several “new airs,” as he called them. Priestly wasn’t a scientist by trade; he was a teacher and writer. However, he loved to play around in his lab at home. One day, he poured acid on a powder, trapped the air it produced, and used it to to put out a flame. (guide performs “carbon dioxide extinguishes fire” experiment) He had discovered carbon dioxide, and later went on to discover eight other gases!

In 1767, Priestly lived next to a brewery – a place where they make beer. He noticed that over the vats where the beer was fermenting, there was a haze of carbon dioxide. He collected this gas, mixed it with drinking water, and invented carbonated water, which he called “windy water.” (guide opens bottle of carbonated water and serves to children)

Now, around that time, sailors in the British Navy were suffering from a deadly illness called scurvy. As you can imagine, a Navy full of sick or dead sailors can’t win any wars! Priestly thought that his windy water could be a cure for scurvy, so he wrote to the British Navy asking them to test his theory. The French Navy was also struggling with this malady, and Priestly’s potential secret remedy was stolen by a French spy! It made its way to the French Navy, who contacted one of France’s most intelligent scientists, a young man named Antoine Lavoisier.

It turned out that Priestly’s windy water, though refreshing, was useless against scurvy. However, it would help to transform alchemy into a serious science: chemistry. But that’s a story for another day…

BOTW: The Story of Money

Is your child afraid of math?  I know many who are.  I also know that one of the most effective ways to help them overcome their fear of math is to give them an allowance.  In addition to teaching your child patience, opportunity cost, and the value of things, money is a hands-on way to work through many math skills!

My son got hooked on math through his allowance.  At the age of four, he wanted to save up for a LEGO kit. On a piece of graph paper, I marked one square for each dollar he would have to save.  Whenever he got his allowance, he would color in the associated squares and we would count how many more squares – or dollars – he needed to reach his goal.  By the age of five, he was using addition to calculate his goals, and by six he was multiplying.  Now that he’s seven, he has a money journal, where he writes down his debits, credits, and current balance.

His interest in money, and his age, led to the question: “Why do we use paper money?  Why don’t we use gold or computers?”

I’m glad we had The Story of Money in our home library!  This lovely book, written by an elementary teacher, traces the fascinating history of world currencies from the time of the very earliest humans. The engaging illustrations and clear text will take you and your child on a journey through ancient civilizations like Sumer and China.  You’ll then make your way to colonial America and discover how the dollar came to be. storymoney

The Story of Money is written in the style of Montessori’s Cosmic Stories, which helps children stay engaged from start to finish.  My son loved looking at all the different ancient coins, all carefully illustrated to actual size.  This book can inspire many avenues of research for elementary students, from timelines to coin collections.

So, the next time your child feels scared of math, connect math to money, and money to human history with The Story of Money, and watch their fear turn to enthusiasm!

The Valentine’s Day Story

Zachary, age 7, asked me how Valentine’s Day started.  I told him we could research that at the library, but later that night I got curious and went online.  I found conflicting information, so I decided to put together a Cosmic Education story to tell him the tale of the origins of Valentine’s day.  I shared it with him and it inspired us to make care packages for the people experiencing homelessness in our area.  I hope it can inspire acts of kindness, or at least get some conversations started, among the children in your life.

Note: I don’t follow any religion, and I’ve tried to make the story as secular as possible so it can be used widely.  I use the lower-case “g” in all instances of the word “god”, but if that bothers you, feel free to copy/paste and edit at will.  This story is meant to be told orally, as are all Cosmic Education stories, so you can adapt it to fit your audience and/or beliefs.

The Story of the Origin of Valentine’s Day

Have you ever wondered where people got the idea to celebrate Valentine’s day?  Historians don’t have much information to go on, so I’m going to tell you one of their theories.  For this story, we’re going to go back in time, almost 2,000 years ago, to a country in Europe called Italy.

Italy was the home of the Ancient Romans.  The Roman Empire was very powerful, with a large army and a series of emperors that controlled land from Northern Africa to Western Asia and a large part of Europe.  The Ancient Romans believed in many gods. You’ve probably heard of Saturn, Jupiter and Neptune… Before they were the names of planets, they were just three of the hundreds of gods the Romans worshipped! Keeping the gods happy was of utmost importance to the Ancient Romans, and the Emperor would throw in jail anyone who didn’t believe in these gods or who refused to make sacrifices to them.

One of the groups of people at risk of being jailed were the Christians.  This small group believed in only one god – a god very different from the Roman gods – and felt their mission in life was to help people who were poor, sick or hurt.  After receiving help from the Christians, these people would often convert – they’d stop believing in the Roman gods and start worshipping the Christian god.  As you can imagine, this made the Roman Emperor very, very angry!

One of these Christians was a priest named Valentinus.  He helped the poor and the sick, and many of those he helped were so grateful that they decided to convert.  When the Emperor heard what Valentinus was doing, he locked him in jail to stop him from helping and converting any more Romans to Christianity.  However, Valentinus did not forget about those he’d helped.  He wrote letters to them from jail and signed them “From your Valentinus.”

Valentinus died in jail on February 14th, which was around the time of the Ancient Roman feast of Lupercalia.  This rowdy party celebrated love, and when the Christians became more powerful than the Romans, they replaced this raucous festival with a day to remember the work of St. Valentinus.  And thus, Valentine’s day was born! You can research how the holiday evolved to include chocolates and love poems; it’s quite an interesting story that will take you to Medieval England.

I look forward to hearing what you discover.  But for now, when we celebrate Valentine’s day, let’s take a moment to think about how we – like Valentinus – can make the world a better place by helping those who are poor, sick or hurt.  Because that’s the true spirit of Valentine’s day!

Montessori: No Holds Barred Education

Some of my 7- and 8-year old students recently received a lesson on the B.C./A.D. timeline. A couple of students decided they wanted to reproduce the timeline (a very long series of paper strips, divided into centuries) and illustrate important historical events on it.

One young 7-year old, a lover of history, was especially engaged with his project, pouring over books to hunt down dates for the sinking of the Titanic, the discovery of America, the building of the Great Pyramids, and the end of World War I.

At one point he approached me and said he wanted to know when the last Ice Age ended. I helped him find the information in a book, and we both learned that, according to that source, the last Ice Age ended about 35,000 years ago. He wanted to know how many centuries that was, so I took this opportunity to give an impromptu long division lesson. I gathered my older students, explained the boy’s conundrum, and asked them to take out the Racks & Tubes (a material for long division).

We set up the problem (35,000/100) and worked out the solution. The other children went back to their individual work and the boy and I returned to his timeline to ponder 350 centuries worth of history.

“The oldest century I have here is the 50th century B.C.,” he said, looking back over the 70 centuries he had marked off.

“Your timeline will need to be five times as long as it is now,” I pointed out, thinking he might not understand what he was getting himself into.

His eyes widened. “Cool!!! Where can I get more strips?”

I think we’re going to need a bigger classroom. 🙂
