Of the many ways Earth is polluted, light pollution may be the least talked about. Defined as excessive or obtrusive artificial light, light pollution has consequences. It can wash out starlight in the night sky, interfere with astronomical research, disrupt ecosystems, have adverse health effects, and waste energy.

Take a moment to watch this short film that shows how the view of the cosmos gets better in less light-polluted areas.

I would also argue that light pollution causes many students to develop misconceptions. These misconceptions arise because we often fail to provide children with the time and opportunity to simply observe the night sky. After all, if you live in a metropolitan area, it does take some planning and a little driving to get out of the city.

How many young children today realize that during the course of a year, our view of the night sky changes from month to month? Some constellations are always in the sky, while others appear and disappear over different regions. How many children – or adults for that matter – can explain the rotation and revolution of our nearest celestial neighbor, our moon?

If you would like to learn more about common misconceptions in science, read my my five-part series.

The Night Sky Each Month

Early in our homeschool journey I read the works of Charlotte Mason. Her words, particularly in regards to the natural world resonated with me,  “We are all meant to be naturalists, each in his own degree, and it is inexcusable to live in a world so full of the marvels of plant and animal life and to care for none of these things.” 

With her words in mind, I have always tried to provide my children with ample time in the outdoors and to develop their observational skills. I also love living books that guide them on their discoveries. One of my favorite for astronomy is The Night Sky Month by Month.  This book, written by Will Gater and Giles Sparrow, shows the sky as it is seen around the world in both the northern and southern hemispheres. It is the perfect guide for amateur astronomers – the illustrated pictures and monthly sky guides will help you recognize patterns and track changes in the each hemisphere.

Another great story that will delight younger readers is The Moon Over Star which puts the historic moon landing into historical perspective through the eyes of a child.

Astronomical Events for Spring 2019

Charlotte Mason and I would encourage you to get outside and observe the night sky year round. Encourage your child to begin documenting his or her observations by keeping a moon journal. Sketch the appearance of the moon each night and note the location it is visible in they sky. To get you started, here are a few key events this spring.

March Equinox ~ The March equinox occurs on March 20th whereupon the Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of spring (vernal equinox) in the Northern Hemisphere and the first day of fall (autumnal equinox) in the Southern Hemisphere.

Worm Moon ~ This full moon phase occurs on March 21st and was known by early Native American tribes as the Full Worm Moon because this was the time of year when the ground would begin to soften and the earthworms would reappear. This is also the last of three super moons for 2019. The Moon will be at its closest approach to the Earth and may look slightly larger and brighter than usual.

Mercury at Greatest Western Elongation ~ The planet Mercury reaches greatest western elongation of 27.7 degrees from the Sun on April 11th. This is the best time to view Mercury since it will be at its highest point above the horizon in the morning sky. Look for the planet low in the eastern sky just before sunrise.

Fish Moon ~ The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated.  Early Native American tribes called this full moon the Full Pink Moon because it marked the appearance of wild ground phlox, which is one of the first spring flowers. Many coastal tribes called it the Full Fish Moon because this was the time that the shad swam upstream to spawn.

Lyrids Meteor Shower ~ The Lyrids is an average shower, usually producing about 20 meteors per hour at its peak. It is produced by dust particles left behind by comet C/1861 G1 Thatcher, which was discovered in 1861. The shower runs annually from April 16-25. These meteors can sometimes produce bright dust trails that last for several seconds. Meteors will radiate from the constellation Lyra, but can appear anywhere in the sky.

Eta Aquarids Meteor Shower ~ The Eta Aquarids is capable of producing up to 60 meteors per hour at its peak in the Southern Hemisphere and about 30 meteors per hour in the Northern Hemisphere. It is produced by dust particles left behind by comet Halley, which has been known and observed since ancient times. The shower runs annually from April 19 to May 28. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.

Blue Moon ~ This full moon will appear on May 18th and was known by early Native American tribes as the Full Flower Moon because this was the time of year when spring flowers appeared in abundance. There are normally only three full moons in each season; a fourth full moon occurs only happens once every 2.7 years, giving rise to the term, “once in a blue moon.”

August 7, 2018

Imagine for a moment, it is the year 1844 and you’re walking down Broad Street in the small coastal town of Lyme Regis on the southern shore of England. Your eyes are drawn to a window of a cottage. Treasures lay on the other side of the glass: coiled ammonite shells long since turned to stone, sea shells carefully arranged in a pattern, and in the center sits the petrified skull of a long-snouted sea reptile with pointed teeth and huge eyes. A sign above the door reads Anning’s Fossil Depot.

This small shop of curiosities was owned by a remarkable woman of her time, Mary Anning. She spent her life collecting the Jurassic-era fossils displayed throughout the small shop, simultaneously providing for her family and unlocking the secrets of Lyme Regis’s ancient past. Today, her shop is a museum.

Born into poverty in a society famed for its class consciousness, the savvy businesswoman defied the odds to become one of the world’s most important scientific figures.

Paleontologist Mary Anning was an impressive fossil hunter who discovered the first articulated plesiosaur and was among the first to identify fossilized poop or coprolite. However, like many females scientists, her male contemporaries had a frustrating way of swiping credit from her.

Short Biography of Mary Anning

Born on the 21st of May 1799, Mary Anning was an English fossil collector and paleontologist. She became known around the world for important finds she made in the fossil beds along the seaside cliffs of the English Channel at Lyme Regis in Southwest England. Her findings contributed to important changes in scientific thinking about prehistoric life and the history of the Earth.

By the late 18th century, Lyme Regis had become a popular seaside resort and many locals supplemented their income by selling what were called “curios” to visitors. These were fossils with colorful local names such as “snake-stones” (ammonites), “devil’s fingers” (belemnites), and “verteberries” (vertebrae). Fossil collecting was a hobby shared by many and it gradually transformed into a science as the importance of fossils to geology and biology was understood.

Her father was a cabinetmaker who supplemented his income by mining the coastal cliff-side fossil beds near the town, and selling his finds to tourists. He married Mary “Molly” Moore in 1793 and together had ten children, though only Mary and one brother, Joseph, survived to adulthood. Their father, Richard, often took Mary and Joseph on fossil-hunting expeditions. Mary continued to support herself through fossil hunting as she grew older. 

While scouring the beach in early December 1823, she came upon a fossilized skull that was like nothing she’d seen before. The majority of the skulls she had previously found belonged to Icthyosaurs; they were long and narrow, a bit like the heads of dolphins or crocodiles.

This skull, on the other hand, was small, beady-eyed, and had a mouthful of strange, needle-shaped teeth. Calling upon nearby villagers for assistance, Anning carefully unearthed the rest of the mystery creature’s body. Attached to a stout torso and broad pelvis were four flippers and a diminutive tail. The long neck was the most peculiar feature, however, accounting for nearly half of the 9-foot creature’s length.

She wrote to a colleague describing her discovery (see a page from her letter below) and her place in the scientific community was sealed, though many of her peers were initially skeptical. In fact, at a Geological Society of London meeting the following year, Reverend William Conybeare (a fellow paleontologist) stole the show with a well-received presentation on the nearly complete Plesiosaurus from Lyme Regis. He also published a paper featuring detailed original illustrations of the specimen. However, neither his presentation nor his paper mentioned Anning and he initially stole credit for the discovery.

Over time, Anning’s discoveries became key pieces of evidence for extinction. Her work also became well known in literary circles as well; Charles Dickens wrote of his admiration of her 18 years after her passing. Legend has it the children’s rhyme, “She Sells Seashells”, is also a tribute to her work:

She sells seashells on the sea shore.
The shells she sells are seashells, I’m sure.
And if she sells seashells on the sea shore,
Then I’m sure she sells seashore shells.

Anning died from breast cancer at the age of 47 on the 9th of March 1847. Admirably, when the Geologic Society learned of her diagnosis, its members began raising money to cover her medical expenses. Later, her funeral was paid for by the society which also financed a stained-glass window dedicated to her memory that now sits at St. Michael’s Parish Church in Lyme Regis.

Bring it Home – Lessons from Mary Anning

Nature journals are as valuable a learning tool today as they were in earlier centuries. The image below comes from a letter written in 1823 by Mary Anning describing her discovery of what would be identified as a Plesiosaurus. Mary Anning Plesiosaurus

Visit a local natural history museum and create a nature journal entry on one of the specimens on display. Inquire with the staff about the process and care involved in curating skeletal specimens.

Participate in a fossil walk.

Begin your own collection of fossils.

If possible, visit the Natural History Museum in London or the museum in Lyme Regis.  We recently had this opportunity when we traveled to England in 2017. Here you can learn more about the pioneering work of Mary Anning and see some of the most complete fossils of prehistoric sea animals, including ichthyosaurs and plesiosaurs. Plus, look out for the skeleton cast of the giant ground sloth, a land mammal often mistaken for a dinosaur.

Novelist Tracy Chevalier (author of The Girl with the Pearl Earring) has made a career of bringing history to life. Chevalier’s newest novel is called Remarkable Creatures centers around the life of Mary Anning. The novel introduces readers to Mary’s unlikely champion, Elizabeth Philpot, a middle-class woman who shares her passion for scouring the beaches. Their relationship strikes a delicate balance between fierce loyalty, mutual appreciation, and barely suppressed envy, but ultimately turns out to be their greatest asset. Based on real characters, I found the story interesting. I was moved to realize just how difficult it must have been to persevere with the social obstacles she encountered in her time.

June 27, 2017

On August 21, 2017, Oregon will be the first to see the total eclipse of the Sun. This much anticipated solar eclipse will be visible across much of the United States. I first learned of this rare occurrence a year ago and quickly made plans to be sure we would be in the path.

Solar Eclipse 2017We purchased tickets to attend OMSI’s Eclipse Party at the Salem Fairgrounds and attempted to make hotel reservations in the area to no avail. We have thereby fallen back on a backup plan – staying with family in Eugene and driving up. I fear, however, that the road will be so congested we won’t reach our destination.

Anticipating the 2017 solar eclipse, I am delighted to share with you a number of lessons and activities with which you can engage your middle school students.

About the Solar Eclipse

A total solar eclipse is when the moon moves right in front of the sun, covering it completely for a very short time. It darkens the whole sky, lets you look right at the sun, and shows you the beautiful corona that surrounds the sun. Stars come out, the horizon glows with a 360-degree sunset, the temperature drops, and day turns into night.

Only look at the sun when it is 100% covered. You must use special solar viewing glasses whenever the sun isn’t completely eclipsed or it may cause irreparable eye damage.

The umbra (fully shaded inner region of a shadow) will hit the shores of Oregon at 10:15:53 am PDT near the small town of Otter Rock. From the time the shadow first touches land, it will take only two minutes for the shadow to race eastward. As the eclipse passes over the state, cities will experience various lengths of totality based on their varying distances from the centerline. At the Oregon State Fairgrounds, we will be treated to one minute and 53 seconds of shadow at just after 10:17am.

The eclipse will continue across the United States where Illinois will experience the longest eclipse duration at two minutes and 41 seconds. South Carolina will be the last state to witness the eclipse and the final shadow will be over the Atlantic Ocean near the west coast of Africa. See a map of the full eclipse path.

Solar Eclipse

Three Types of Eclipses

Solar eclipses occur during the new moon phase when the Moon moves between the Earth and the Sun and the three celestial bodies form a straight line, Earth-Moon-Sun. There are three kinds of solar eclipses, Annular, Partial, and Total. On even more rare occasions, a hybrid eclipse occurs when there is a combination of two.

Annular Eclipse

An annular eclipse occurs when the Moon covers the Sun’s center, yet the moon’s shadow doesn’t quite reach the Earth. The Sun’s visible outer edges thus form a “ring of fire” or annulus around the Moon. The ring of fire marks the maximum stage of an annular solar eclipse.

We have been fortunate to observe an eclipse in the past. In 2012, we enjoyed an annular eclipse near Red Bluff, California.

Partial Eclipse

A partial eclipse, which are visible to a greater number of people due to its wider path, occurs when the Moon comes between the Sun and the Earth, but they don’t align in a perfectly straight line and thus the Moon only partially covers the Sun’s disc. A Partial Eclipse can be seen on either side of the path of totality where the moon doesn’t completely cover the sun.

Total Eclipse

A total solar eclipse occurs when the Moon comes between the Sun and Earth and completely covers the face of the sun, letting the sun’s magnificent corona burst into view, and casts the darkest part of the shadow (the Umbra) on Earth. In this shadow, the Earth is almost as dark as night.

Check out the 2017 Solar Eclipse explainer video we created with mysimpleshow.

Hybrid Eclipse

A hybrid solar eclipse occurs when the eclipse changes from an annular eclipse to a total eclipse along the path of the moon as it rotates about the Earth.

Science with Harry Potter: Alchemy @EvaVarga.net Alchemy 

Alchemy is an elective taught at Hogwarts School of Witchcraft and Wizardry concerning the study of the four basic elements, as well as the study of the transmutation of substances. It is intimately connected with potion-making and chemistry but for purposes of clarity, this post will focus on transformation of rocks and minerals.

I’m particularly interested in Transfiguration, you know, turning something into something else, of course, it’s supposed to be very difficult.” —Hermione Granger regarding transformation

There are many myths and legends about the formation of the rocks of the Earth or about the rocks themselves. Every culture has its own beliefs about specific stones and those beliefs are often tied to that culture’s history, geography, and spiritual practices.

For this class students are required to become familiar with the many magical properties of common stones. Begin by writing the definitions for igneous, metamorphic, and sedimentary rock in a notebook. Include a detailed sketch of the rock cycle.

Additionally, create a two-page spread for each stone studied. Include the following information for each:

  1. photo or sketch
  2. list any historical or literary references to the gemstone
  3. describe the process by which it is formed
  4. list its magical properties

Some stones to consider are:

  • Agate
  • Quartz
  • Ruby
  • Opal
  • Flint
  • Moonstone
  • Jade
  • Obsidian

Put together a collection of rocks and minerals. Identify and label each as igneous, metamorphic, or sedimentary.

Learn to play Marbles, generally a Muggle game. Wizards play a variant known as Gobstones, where the enchanted marbles spit a putrid fluid into the face of the loser.

Science with Harry Potter: Potions @EvaVarga.net Astronomy & Divination

At Hogwart’s, Divination is an elective course that teaches methods of divining the future, or gathering insights into future events, through various rituals and tools. For the purposes of this course, we will focus on the ancient tools used by early navigators particularly in regards to the study of astronomy.

Generally out-of-bounds except for classes, the Astronomy Tower is the tallest tower at Hogwarts Castle. It is where students study the stars and planets through their telescopes with Professor Aurora Sinistra.

A Star chart is a written document used to represent the positions and movements of the stars, much like a map. Astronomers usually use these for research or study. An O.W.L. level wizard should be able of fill in a blank star chart based on some hours of sky gazing.

Similarly, a Moon chart is used to represent the position, movement and phases of the Moon. However, it is difficult to interpret and thus a Lunascope is often preferred.

Begin by researching the constellations common in your hemisphere and/or those referenced in the books.

Illustrate each cluster of stars in your notebook and make note of when the constellation was first discovered and how it was named. Include the names of the distinct stars (if possible).  Constellations to consider include:

  • Orion
  • Bartholomeus
  • Lupus
  • Leo
  • Ophiuchus
  • Canis Major
  • Scorpius

Create personal chart (also referred to as a birth chart) showing the relative positions of the planets at the time of an individual’s birth.

If possible, obtain a telescope with which you can observe the planets and distant stars.

Take it Further

Create a model of our solar system. Include the moons of Jupiter, Saturn, and other major planets.

Make an illustrated wall timeline of geologic time.

Draw maps of the earth at various times in history, showing movements of the tectonic plates. Include time periods that show Pangaea, Laurasia and Gondwanaland, and the modern arrangement of continents.

Illustrate the layers of the atmosphere in a poster. Label and describe each layer.

April 15, 2017

In my Facebook newsfeed recently, a memory popped up highlighting a field trip we took part in years ago when we first began our homeschool journey. Our visit to Paleo Lands Institute in Eastern Oregon is one of our fondest homeschool experiences. When we visit the Field Museum in Chicago last week, we reflected on this trip as we marveled at the many specimens they had on display – the most impressive, of course, was SUE (pictured below).

The unveiling of her 67-million-year-old skeleton at The Field Museum made global headlines in May of 2000. As the largest, best-preserved, and most complete Tyrannosaurus rex ever found, she is considered to be the most famous fossil ever found. She measures 40.5 feet long from snout to tail and 13 feet tall at the hip.

Interesting fact: While SUE is frequently referred to as a “she,” scientists don’t actually know her sex.

Virtually all parts of SUE’s skeleton are preserved in great detail—even the surface of her bones. Scientists can actually see where muscles, tendons, and ligaments once attached. Not only are most of the bones undistorted from fossilization, but cross-sections of the bones show that even the cellular structure inside remains intact.

w/ Sue at the Field Museum, Chicago

If SUE is the most famous fossil, who then is regarded as the most renowned fossilist the world ever knew?  The answer is Mary Anning.

Despite the fact that Mary Anning’s life has been made the subject of several books and articles, comparatively little is known about her life, and many people were unaware of her contributions to paleontology in its early days as a scientific discipline. How can this be, you ask?

Biography

Mary Anning by B. J. DonneMary Anning was born on the 21st of May 1799 to Richard and Mary Anning in Lyme Regis, Southwest England. Mary grew up in a prime location to lead a life of fossil collecting. The marine fossil beds in the cliffs in this area remain today a huge source of fossils from the Jurassic period.

Her findings contributed to important changes in scientific thinking about prehistoric life and the history of the Earth. At the age of 12, Mary Anning was to become one of the most famous popular palaeontologists, with her discovery of a complete Icthyosaur.

Interesting fact: Though she is now credited with the discovery, her brother had first found the specimen. Mary did find the majority of the remains and contribute significantly to the excavation work. Mary went on to find two more species of Ichtyosaur in her life.

In early 1821, Anning made her next big discovery with the finding of the first Plesiosaurus. She sent a drawing she made to the renowned George Curvier, who at first snubbed it as a fake. Upon further examination, he eventually reversed this statement finally giving Anning the respect she had deserved from the scientific community. This discovery is perhaps her most important find, from a scientific point of view.
Autograph letter concerning the discovery Wellcome L0022370
The majority of Mary’s finds ended up in museums and personal collections without credit being given to her as the discoverer of the fossils. There are many factors contributing to this error: the lack of appropriate documentation of her special skills, her social status, and more importantly, her gender. Many scientists of the day could not believe that a young woman from such a deprived background could posses the knowledge and skills that she seemed to display.

For example, in 1824, Lady Harriet Sivester, the widow of the former Recorder of the City of London, wrote in her diary after visiting Mary Anning:

“. . . the extraordinary thing in this young woman is that she has made herself so thoroughly acquainted with the science that the moment she finds any bones she knows to what tribe they belong. She fixes the bones on a frame with cement and then makes drawings and has them engraved. . . It is certainly a wonderful instance of divine favour – that this poor, ignorant girl should be so blessed, for by reading and application she has arrived to that degree of knowledge as to be in the habit of writing and talking with professors and other clever men on the subject, and they all acknowledge that she understands more of the science than anyone else in this kingdom.”

After her death on the 9th of March 1847, her unusual life story attracted the attention of scholars around the world. Her story was the inspiration for the 1908 tongue-twister “She sells seashells on the seashore” by Terry Sullivan and in 2010, one hundred and sixty-three years after her death, the Royal Society included Anning in a list of the ten British women who have most influenced the history of science.

February 10, 2017

Nea Kameni is the eastern Mediterannean’s youngest volcanic landform, and today it is a protected natural monument and national geological park. Nea Kameni and the neighbouring small island Palea Kameni (the new and old burnt islands) have formed over the past two millennia by repeated eruptions of dacite lava and ash. The most recent eruption occurred in January 1950 when the volcano dropped lava within a range of 850 meters, and explosions lasted for three weeks.

“This year a small islet, hitherto unknown, made an appearance close to the island of Thera.” ~ Roman historian, Cassius Dio, 47 AD

Volcanic Nea Kameni @EvaVarga.netNea Kameni is visited daily by dozens of tourist boats. We were amongst them – enjoying an late afternoon cruise in a kaiki (traditionally, a small wooden trading vessel, brightly painted and rigged for sail) to the volcanic island within the flooded Santorini caldera.

This excursion can be bought in any hotel in Santorini, as it is very popular. Boats leave from the new harbor, Fira, and it takes about 20 minutes to travel to the volcano in the middle of the caldera.

Nea Kameni

Upon arrival, we hiked a gravel path to reach the top of the 130-meter-high volcanic crater. There is a small entrance fee to help pay for the upkeep and the monitoring systems.

The ascent to the rim of Nea Kameni requires walking up some unstable terrain, under Santorini’s trademark blazing sun. We were glad we wore comfortable sandals and protective gear to shield us from the hot rays. From here we had a magnificent view of Thira (Santorini) before returning to the kaiki along the same path.

Magma exists at depths of a few kilometers; it’s visible through hot springs and hot gases, giving Nea Kameni its trademark sulfuric aroma. The kids got a kick out of the fact that we hiked the rim of a volcano inside another volcano! 

Palea Kameni @EvaVarga.netPalea Kameni

After the hike, we sailed to the volcanic islet of Palea Kameni where we could enjoy a short swim to a protected bay along the shore. The water went from green to orange-brown and we all giggled when we began to feel the temperature change, the hot and cold perfectly showing the effect of the waters coming up from below within the volcano.

You could just feel the tension melt away after a unique afternoon swim in the heated waters of the thermal springs. Although it wasn’t hot enough to be dubbed a ‘hot spring’ we found the water temperature to be refreshing after our hike on nearby Nea Kameni. Yes, our clothes did get stained a little but we had been forewarned.

We closed the evening with a wonderful buffet dinner aboard the kaiki as we watched the sunset over the islands. It was spectacular conclusion to our holiday in Greece.
