I’ve been thinking a lot about turkeys lately! If you are in the United States, you might be celebrating the Thanksgiving holiday on Thursday. It is a celebration of thanks commemorating the first harvest feast the Pilgrims had in 1621. Today families often gather to have a big feast of foods and that meal might include a roasted turkey.  So, I’ve been thinking about turkeys.

One of my first thoughts led me to wonder where the word “turkey” originated. Why are they called turkeys? An article in the Atlantic Monthly had a good explanation. You can read it here. I was pretty surprised to find that the origin of the word is debated by etymology experts.

Then I was wondering if turkeys can really fly and I started to investigate. Sure enough, they can fly! This investigation led me to thinking about the wishbone in the turkey at our family Thanksgiving celebration. It’s the “wishbone” that is the bone that connects the wings of birds allowing them to fly.

So what do Tyrannosaurus Rex, the Velociraptors, and turkeys all have in common?  I was amazed to find out that many dinosaurs, including the newly found “Mud Dragon” had wishbones. Yep! The wishbone is actually called the “furcula” and is found in birds and in DINOSAURS!

Next time you eat a turkey and find the furcula, remember that scientists have found that the wishbone dates back more than 150 million years!

HAPPY THANKSGIVING!

The Nobel Prizes

International Campaign to Abolish Nuclear Weapons

In November of 1895, Alfred Nobel passed away and left a very large amount of his money to go toward a variety of prizes. The prizes became known as the Nobel Prizes. It was a generous beginning to yearly honor work in the sciences, literature, and those people working for peace throughout the world.

I am always most interested in The Nobel Peace Prize. Alfred Nobel’s will stated that the Peace Prize would go to “the person who shall have done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses.”

The 2017 award went to an organization, rather than one person. The Nobel Peace Prize 2017 was awarded to the International Campaign to Abolish Nuclear Weapons (ICAN). This is a world-wide partnership of organizations dedicated and focused on a nuclear weapon ban treaty for the world. What an honorable intention to free the world’s people from the use of a nuclear weapon.

In 1904 Ivan Pavlov won the Nobel Prize in Physiology or Medicine. Some of you may have already studied about him and his ideas. You may be studying Pavlov’s work in the Oak Meadow curriculum. On the Nobel Prize website there are educational pages that have some fun facts and games to play. The one about Ivan Pavlov is great!

It is also fascinating to watch the lectures and the award ceremonies. You can view them at: http://www.nobelprize.org/

THE AUGUST ECLIPSE!!

Solar and Lunar Eclipses Worldwide

Solar and Lunar Eclipses Worldwide

Hello! Here in New England we have had a good summer and it isn’t over yet! There are still weeks to go in August of lazy summer days and cool nights. Here at Oak Meadow one event we are all looking forward to is the upcoming eclipse on August 21, 2017. The following is a quick blast of great information from DeeDee Hughes, our Oak Meadow colleague:

Hi Folks,

We are all a little eclipse-crazy here in Corvallis, Oregon since we are in the “zone of totality” for viewing the total solar eclipse on August 21. I did some research and found this cool interactive map that shows the path of eclipses for years to come. I found a page where you can type in a city name and see what the eclipse will look like from there–I couldn’t resist checking out where friends and family members live. It’s fun to compare different places:  

Brattleboro VT

Santa Cruz CA

Corvallis OR

Seems like everyone in the country will be seeing something cool. Oh, and this article has good info about the solar eclipse glasses and how to tell if you have safe ones. 

I was wondering why the upcoming eclipse is being called “Eclipse of the Century” when they happen all the time, so I dug deeper. A total solar eclipse is different than an annular eclipse, but both have the moon lined up exactly in between Earth and the sun. In an annular eclipse, the moon moves fully in front of the sun but because the moon is further from the Earth at that time, there will be a “ring of fire” seen around the moon, rather than having the moon block the sun entirely the way it does in a total solar eclipse. The difference between an annular and a total solar eclipse is the distance between the moon and Earth. Here’s an article with a cool “ring of fire” photo. 

That’s my two cents on cool eclipse fun! DD

I’ll also add that EARTHSKY has a very good “Eclipse Day” checklist for getting ready for viewing. Be prepared, have fun, and enjoy the “Eclipse of the Century” with family and friends!

 

Stamp Collecting!

“The word ‘philatelist’ means a person who practices philately or stamp collecting. It comes from the French word ‘philatelie’, which was derived from the Greek words ‘philos’, meaning loving, and ‘atelia’, meaning exemption from tax which also came to mean ‘postage is prepaid.’.”

American Philatelic Society

The American Philatelic Society is the largest, nonprofit organization in the world for stamp collectors.

When I was little and traveled with my family, we didn’t have computers for emailing and so we wrote lots of letters to family and friends. We also made a tradition of mailing ourselves letters to our own home! We would go to a post office in a country or town that we were visiting, and purchase a special stamp. (You can ask the post master to show you what stamps he/she has available.) Then, using the stamp, we would mail the letter home to ourselves. It was fun to see the letters and the stamps when we arrived home. I don’t have a very big collection of stamps, but the ones that I do have hold some wonderful memories for me.

This year a really cool stamp is going to be offered! A first of its kind! Some background first:

You may have read that there is going to be a total eclipse of the sun across the United States this summer. (Monday, August 21, 2017.) People from all over the world will be coming to different spots in the United States to witness this solar eclipse.

What does a solar eclipse have to do with a stamp? Well, the Postal Service will be offering a first-of-its-kind stamp! It changes when you touch it! The Postal Service announcement says: “The Total Eclipse of the Sun, Forever® stamp, which commemorates the August 21 eclipse, transforms into an image of the Moon from the heat of a finger.”

You can read the story of how the stamp was designed here.

If you would like to view other stamps that have commemorated eclipses, you can view them here.

So, as you travel to new places, or even stay in your hometown, take a look at the many stamps that the post office has to offer!

P. S.  Looking directly at the sun during a solar eclipse can be dangerous; here’s a way to enjoy the eclipse without hurting your eyes: http://hilaroad.com/camp/projects/eclipse_viewer/eclipse_viewer.html

 

A Day to Remember: Memorial Day

Memorial Day, celebrated in the United States on the last Monday of May, is a day in which we honor those men and women (and service dogs) that died while serving the country in the United States armed services.

The day actually started as a way to commemorate those that died during the U.S. Civil War. In 1868 it was established and it was called “Decoration Day.” At that time it was on May 30th and was a day to decorate the graves of those that died in the Civil War.

In 1967 Memorial Day became a national holiday. In 1971 the holiday was moved to the last Monday in May. On the U.S. Department of Veteran Affairs website, it states: “In December 2000, the U.S. Congress passed, and the president signed into law, “The National Moment of Remembrance Act,” P.L. 106-579, creating the White House Commission on the National Moment of Remembrance.”

The law actually requires that U.S. citizens pause, for one minute at 3:00 p.m. on Memorial Day, and honor those that have died in service to our country.

 

The Night Sky

This week’s night sky
(Northern Hemisphere)

“You cannot teach anybody anything. You can only help them discover it within themselves.” ~~ Galileo ~~ (15 February 1564 – 8 January 1642)

I love to go outside on a clear night and observe the stars and planets. Last night the incredibly beautiful full moon was so bright that it was hard to see any constellations! I took a walk in the moonlight and thought about how strong the light from our sun is that our moon can reflect enough light for me to see where I am going at 10:00 at night. Awesome! In the 7th grade science curriculum, Oak Meadow students investigate the moon, its phases, and its gravitational pull on Earth. Students also learn to compare the characteristics of the planets in our solar system. The study of astronomy is so fascinating!

Sky viewing is a great time for gathering friends on an evening and doing some star watching. If you know there will be a clear night for star viewing, it’s a great time to HAVE A STAR PARTY!

Send invitations, make “star” snacks, and put lots of blankets on the ground for friends to sit down on for good viewing. It’s fun to have some binoculars, a telescope, or one of the free astronomy apps available. Make sure you have flashlights for looking at books of constellations!

Some towns have astronomy clubs and the people in the clubs are usually very willing to come join in the fun and help answer star gazing questions. The Astronomical Society of Northern New England can be contacted for Star Parties!

“This Week’s Sky at a Glance” at the Sky and Telescope website is really helpful for learning what is visible in your own evening sky. Check it out for the constellation guide covering the whole evening sky. Observing the night sky is such a fun activity on a sparkling clear night!

Great idea!

My father is about to turn 94 and consequently, we go all out for his birthday parties! We have a tradition of having him tell us what he was doing at the present age of each member of the family. This past year the youngest among us was a great grandson just 13 months old. It was fun to hear my father speak about what he was doing when he was 13 months old. The oldest at the party was 68 years and that too was amusing!

We decided this year to list many of the things that had been invented in the years since our father (grandfather or great grandfather) was born. Each family member brought a description of the invention to the party. Wow! He has certainly seen many, many inventions in his lifetime!

I think we take for granted some of the inventions he saw in his lifetime, such as the color TV or the black box flight recorder. Lithium batteries and the pocket calculator surprised all of us as just being invented in the 1970s.

Not only do I think we take these inventions for granted, but I think we also pay little attention to the people that invented them! Physicists, biologists, chemists, carpenters, farmers–you name it and you may find a profession that has an inventor. Where do these inventors come from? “From 1900 onwards, on average about 10% of Americans have been first-generation immigrants. Yet first-generation immigrants have won 33% of all American Nobel prizes in the sciences since the award began in 1900, representing thirty-five countries from six continents.” (https://m.facebook.com/notes/neil-degrasse-tyson/science-in-america/10155202535296613/)

All this talk about past inventions got me wondering what is being invented (and patented) right now! I found out about The Lemelson-MIT Program which strives to celebrate  “outstanding inventors and inspires young people to pursue creative lives and careers through invention.” It is so interesting to read about the most recent inventions that are being awarded!

Do you have something that you are working on that will one day be an invention that will benefit us all? Join an inventor’s club! Here’s a list of them by state: http://www.freeinventorshelp.com/Organizations.html#states

Good luck!

Sound Waves and Sonic Booms

Why am I playing a Pink Floyd album as I write my blog? Well, I just couldn’t resist after reading about the newly found shrimp that is named after the band! The legend goes that Pink Floyd once played their music so loudly at a concert that the sound waves killed the fish in a nearby pond.

anothershrimpinthewall-fullres by katepocklington.jpeg

The shrimp has a very large pink colored front claw that it uses to kill its prey. It uses the claw by snapping the pink claw and creating a sound so loud that it can kill small fish. So the scientists (Sammy De Grave of the Oxford University Museum of Natural History, Arthur Anker of the Universidade Federal de Goiás in Brazil and Kristin Hultgren of Seattle University) thought it would be a great honor to name the new species of shrimp “Synalpheus Pinkfloydi” after the band Pink Floyd!

A cartoon version of the Pink Floyd pistol shrimp is shown in this handout photo. (Chris Jarvis / Oxford University Museum of Natural History)

This little shrimp creates volumes of sound up to 210 decibels! If you are in the 8th grade physics course with Oak Meadow,  you study sound waves, sound pressure, and sound power and the impact they have on wildlife and humans. You will also study decibels, the speed of sound, and the way sound travels. So when I write that the sound created by the snapping of the claw can reach 210 decibels, you know THAT IS LOUD!!!

Earth Day

Earth Day first began on April 22, 1970. Inspired to improve environmental protection laws in the United States, Gaylord Nelson, a Senator from Wisconsin, together with Pete McCloskey, a Congressman, and Denis Hayes, selected as the Earth Day organizer, joined forces to promote a day of events to bring public awareness to air and water pollution throughout the United States. People from all over the United States planned clean-up activities and rallies for improving the health of the environment. The event was so powerful that the United States Environmental Protection Agency was created and later, in 1990, Earth Day became a global event.

Celebrate Earth Day on April 22nd with your family! This year the Earth Day theme centers around environmental and climate literacy. You can find more information here.

After a successful day of “creating your own act of green,” take the opportunity to watch (57 minutes) the first in the series of 7 videos about the planet Earth brought to you by Annenberg Learner Media.

 

 

Women's History Month

In the United States, March has been designated as Women’s History Month, and it can be a great time to spend time learning about important women who have made, and are making, contributions to our world.

In celebration of the contributions of women in the United States, our blog post this week is written by Deb Velto, a teacher with Oak Meadow. She shares a special interest in the contributions of a woman named Temple Grandin. Thanks to Deb!

Temple Grandin is an animal scientist who was recently inducted into the National Women’s Hall of Fame because of her work to improve the welfare of animals in the meat industry. Temple has a special ability to understand the animals she observes. Because of this gift, Temple was able to design a method of holding animals at a slaughterhouse that was more humane and would reduce the stress the animals experienced. She could see the stress the animals were experiencing and understand what would help them. Today, her methods are used by the meat industry throughout the world. Temple Grandin’s mind works differently than most scientists because she has autism. Although she has had to overcome many challenges related to being autistic, she attributes the way her mind works with her ability to understand animals.

Temple Grandin eventually became an important advocate for people with autism because she was one of the first people who was able to explain to others what it was like to be autistic. Her insights have helped parents and teachers learn to improve the way they interact with and teach autistic children. She invented something called a “squeeze box” which is still used today to comfort children and adults who have autism. Because her parents and others took the time to learn the way her mind worked, Temple was able to succeed. Today, Temple works to help people better understand autism through her books and lectures. She also continues her work for animals as a scientist and professor at the University of Colorado. Temple Grandin believes that the world needs all kinds of minds.  Do you agree? Do you know anyone like Temple, who may have a special gift, but also faces challenges because of the way their mind works? How do you think we can help people better understand and appreciate these kinds of differences?
