Anticipating the 2017 Solar Eclipse: Activities & Lessons for Middle School

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.

There won’t be another total solar eclipse over the United States until 2024. After that, you must wait until 2045.

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.

10 Websites and Genealogy Resources for Kids

This past autumn, we enjoyed a family holiday on the East Coast of the United States and were thereby afforded with numerous educational experiences exploring our nation’s history. One of our most anticipated visits was to Ellis Island and the Museum of Immigration.
genealogy for kids

While here, we enjoyed a guided interpretive walk with a park ranger and thereafter enjoyed the many exhibits on our own. Amongst the highlights of our visit was seeing Norwegian bunad and langeleik, a stringed folklore musical instrument also known as a droned zither. As both my husband and I have Norwegian ancestors, seeing these personal artifacts brought the experience alive for us.

Genealogy Resources for Kids

Genealogy has always been fascinating to me. I grew up listening to stories my dad would share of his childhood and the stories that had been passed on to him by his Uncle Sam who had emigrated from Norway in the early 1900s.

Science Milestones: The Heroine of Lyme Regis, Mary Anning

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.

Mythological Secrets of Greece: Nea & Palea Kameni

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.

Mythological Secrets of Greece: The Lost City and Paradise in Santorini

Comprising of small circular archipelago of volcanic islands in the southern Aegean Sea, Santorini (locally known as Thira) is all that remains of an enormous volcanic explosion. The island’s spectacular physical beauty coupled with its dynamic nightlife makes it one of Europe’s most popular hotspots.

A Lost City & Paradise in Santorini @EvaVarga.netSantorini Eruption

During the Bronze Age, geologists called the then-circular island of Santorini, Strongyli, which means rounded. After a devastating eruption, however, Strongyli collapsed into the Aegean Sea, creating Santorini’s now-signature crescent shape, as well as several surrounding islands.

Santorini volcano has erupted 11 times so far, but it is believed that the eruption in ~1630 BC was one of the most explosive in history. There is a theory that this eruption indirectly affected the disappearance of Minoan civilization on the island of Crete, by creating a gigantic tsunami.

Minoan civilization was considered to be the most culturally advanced society of that time. Another known theory says that this eruption is the source of the legend of Atlantis.

The Lost City of Akrotiri, Santorini @EvaVarga.netAkrotiri

One of the most memorial excursions we enjoyed while in Santorini was a visit the prehistoric Akrotiri, believed to be associated with the Minoan civilization, located on the nearby island of Crete. The earliest evidence for human habitation of Akrotiri can be traced back as early as the 5th millennium B.C., when it was a small fishing and farming village.

By the end of the 3rd millennia, this community developed and expanded significantly due in part to the trade relations it established with other cultures in the Aegean, as evidenced in fragments of foreign pottery at the site. Akrotiri’s strategic position between Cyprus and Minoan Crete also meant that it was situated on the copper trade route, thus allowing them to become an important center for processing copper, as proven by the discovery of molds and crucibles.

The large extent of the settlement, the elaborate drainage system, the sophisticated multi-story buildings with magnificent wall-paintings, furniture and vessels, show its great development and prosperity. The various imported objects found in the buildings indicate the wide network of its external relations, including the Greek mainland, Cyprus, Syria, and Egypt.

The town’s life came to an abrupt end in the last quarter of the 17th century BC when the inhabitants were obliged to abandon it as a result of severe earthquakes. Upon the eruption that followed, volcanic materials covered the entire island and buried the town, similar to Pompeii. In contrast, the excavations here revealed no human remains exist, indicating the people had time to evacuate.

Cycladic Architecture in Pyros @EvaVarga.netPerivolos & Pyrgos

On our first morning on Santorini, the coach drove to Profitis Ilias, the highest point on the island, for stunning views. There are more than 300 churches and monasteries located here and many of the iconic blue domed structures were visible from our vantage point. Thereafter, we enjoyed a walking tour of the village of Pyrgos to see the classic Cycladic architecture.

In the afternoon, we made our way to the black sand beach of Perivolos, passing picturesque villages. Here we enjoyed a traditional Greek meal at a beach side restaurant before spending the remainder of the day in leisure, swimming and sunbathing.

Paradise of Oia @EvaVarga.netOia

Often touted as the most picturesque village in the Greek islands, Oia is perched upon the island’s craggy northwestern edges. With its stunning views of the caldera and surrounding islands, blue and white church domes, and lack of power lines to clutter its panoramas, Oia is paradise.

Red, white and black volcanic rock decorate curvy footpaths, and there are other delightful elements: whitewashed windmills, fuchsia bougainvillea blooms trailing on buildings, and the occasional mural or quirky shop decoration to inject a bit of whimsy.

Oia was most prosperous in the late 19th and early 20th centuries, thanks to its merchant fleet, which engaged in trade in the Eastern Mediterranean, particularly from Alexandria to Russia. Today, large number of tourists visit this place during afternoons to witness one of most beautiful sunsets in the world. This is also most photographed scenery in all of Greece.

Mythological Secrets of Greece: The Island of Delos

The island of Delos is located near the center of the Cyclades archipelago and is one of the most important mythological, historical, and archaeological sites in Greece. It held had a position as a holy sanctuary for a millennium before Greek mythology and by the time of the Odyssey, the island was already famous as the birthplace of the twin gods Apollo and Artemis.

From our base in Mykonos, we made an excursion to the nearby Delos (just 30 minutes by boat) and spent the day here with a local specialist learning about the history of the small island. Today, it is inhabited only by an antiquity guard and an employee of the Archeological museum and is recognized as a UNESCO World Heritage Site.

Delos @EvaVarga.net

Ongoing excavation work takes place under the direction of the French School at Athens and many of the artifacts found are on display here at the Archaeological Museum of Delos as well as on the mainland at the National Archaeological Museum in Athens.

In the past, Delos was an ancient center of worship – a temple to the twins Apollo (god of the sun, music, and healing) and Artemis (goddess of the moon, maidenhood, and archery). It was here that it is believed Leto gave birth to her children; fathered by Zeus.

Delos, if you would be willing to be the abode of my son Phoebus Apollo and make him a rich temple; for no other will touch you, as you will find: and I think you will never be rich in oxen and sheep, nor bear vintage nor yet produce plants abundantly. But if you have the temple of far-shooting Apollo, all men will bring you hecatombs and gather here, and incessant savour of rich sacrifice will always arise, and you will feed those who dwell in you from the hand of strangers; for truly your own soil is not rich.
 Homeric Hymn to Delian Apollo 51–60

During the Hellenistic period (323 – 30 BC), it became one of the most important center for commerce and religion in Greece. Its inhabitants were wealthy merchants, seafarers and bankers who came from as far as the Middle East. The Romans made it a free port in 167 BC, which brought even greater prosperity to the island. The shift in trade route and the waning interest in ancient religion in the following centuries brought the decline of Delos.

It was fascinating to walk along the streets and homes of ancient Delos. Though not as completely excavated or restored as Pompeii, it is much older. Most fascinating to me were the intact mosaics on the floors; the more elaborate and intricate the design, the more wealthy the home owners. In the House of the Dolphins the atrium mosaic features erodes (winged gods) riding dolphins.

Delos: House of Dionysus floor mosaic @EvaVarga.House of Dionysus

The House of Dionysus was a luxurious 2nd century private house named for the floor mosaic of Dionysus riding a panther. The mosaic depicts the god with outstretched wings and ivy wreath, mounted on a panther with a wreath of vine branches and grapes around its neck. In his right hand the god grasps a thyrsus, a staff crowned with ivy, as if it was a spear.

On the ground, between plants, a kantharos, a wine vessel, another attribute of the god of wine. The wings suggest a Dionysiac daimon, a supernatural being acting as an intermediate between gods and men, rather than the god himself.

The Terrace of Lions

The Terrace of the Lions (pictured at bottom in the collage above) was dedicated to Apollo by the people of Naxos shortly before 600 BCE. Originally there were nine to twelve marble lions guarding the Sacred Way. The lions create a monumental avenue comparable to Egyptian avenues of sphinxes. Today only seven of the original lions remain.

Delos: House of Cleopatra @EvaVarga.netHouse of Cleopatra

The remains of the House of Cleopatra (138 BC), a dwelling of a wealthy merchant family. It was named after the wife of the owner. Headless statues of the owner of the house, Dioscourides and his wife, Cleopatra, are visible here.

The open floor plans of the homes permitted natural light and fresh air to circulate. The city also featured a complex underground sewage system. Located near the theater is a cistern, evidence of the advance water system developed by the ancient inhabitants to overcome the shortage of fresh water supply in the island.
