## Science Milestones: The Art and Science of Rube Goldberg

July 3, 2016

Rube Goldberg was a famous cartoonist who took simple and compound machines which are meant to make tasks easier, and made them overly complex. His cartoons depicted complex machines that worked in an indirect and convoluted way, such as the “Self-Operating Napkin”.

### Rube Goldberg Physics

When Goldberg showed his “Self-Operating Napkin” machine to his friend, his friend said it would not work. Using what you know about mechanical advantage and work, prove to Goldberg’s friend that the invention will actually work.

Work (in Joules, J) = Force (Newtons, J) x Distance (m)

Mechanical Advantage of a Lever = Distance from fulcrum to the applied force / Distance from fulcrum to weight lifted

You raise your spoon of soup 0.15 meters with 2 Newtons of force. How much work did you do?

The spoon pulls a string as you move it. How much work is transferred?

The string jerks the ladle, which is a lever. The string is attached 10 cm from the fulcrum and the force is applied 0.5 m from the fulcrum. What is the mechanical advantage?

The spoon throws a cracker past a parrot. The parrot jumps after the cracker, applying force to the perch he is sitting on. The perch spins around throwing the seeds into a pail. The perch is another lever. It has a mechanical advantage of 2. If it would take 0.5 J of work to move the seeds 0.1m without the lever, how much force will be needed with the lever?

The extra weight in the pail pulls a cord, which goes around a pulley and opens and lights an automatic cigar lighter. If the pail can apply 3 N of force to the cord, and the pulley system has a mechanical advantage of 2, how much total force can be applied to the match?

The match sets off the rocket, which causes a sickle to cut the string, allowing a pendulum with attached napkin to swing back and forth thereby wiping off your chin. If 3 N of force is needed to strike the match, will the system work?

### Biography

Reuben Lucius “Rube” Goldberg was born on July 4, 1883, in San Francisco, California. He loved to draw and received some basic art instruction when he worked with a sign painter as a young teen. Rather than pursue a career in art, though, he followed his father’s advice and attended the University of California at Berkeley, where he earned his degree in engineering.

Mapping out sewer pipes and water mains in San Francisco didn’t hold Rube’s interest for long, though. He began creating cartoons for local San Francisco papers. He eventually moved to New York where he landed a job as a cartoonist for the Evening Mail.

He used his engineering background to create funny cartoons featuring complicated machines that were described as new inventions to accomplish easy, straightforward tasks through a series of convoluted steps involving chain reactions. The public quickly fell in love with Rube’s inventions.

His work became popular nationwide, as his cartoons were syndicated in hundreds of newspapers across the country. The art world also loved his works, some of which were displayed in the Museum of Modern Art in New York City. Rube even made it to Hollywood, where his move script “Soup to Nuts” introduced a trio who would soon become famous as the Three Stooges.

## The Raven: A Mini Unit for Middle School

October 31, 2015

I have been fascinated with ravens since I was a child. I recall my mother reading aloud Edgar Allan Poe’s The Raven at Halloween. Poe was one of her favorite authors and she delighted in reading this glorious poem in narrative voice.

New research has found that ravens remember prior interactions with people and even communicate these interactions with others of their kind. I’ve read stories of ravens leaving trinkets and gifts for those who have shown them kindness. My father has a pair of ravens that visit him regularly and when we visit, they can always be seen perched nearby keeping an eye on things.

## Raven Mini Unit

Yesterday, I stumbled upon an Audubon post, How to Tell a Raven From a Crow on Facebook and the wheels in my head immediately started spinning. Would not this make a wonderful Halloween themed mini unit? Yes! I must put something together …

### Science

The Audubon link I shared above is the perfect place to begin. While ravens and crows may look similar in some ways, there are several distinctive traits that help set them apart.

You probably know that ravens are larger, the size of a red-tailed hawk. Ravens often travel in pairs, while crows are seen in larger groups. Also, watch the bird’s tail as it flies overhead. The crow’s tail feathers are basically the same length, so when the bird spreads its tail, it opens like a fan. Ravens, however, have longer middle feathers in their tails, so their tail appears wedge-shaped when open.

Go outside and watch them. Bring along your nature journal and record your observations. How many do you see? How do they interact? What are they eating? Do they scratch at the soil with their feet? What sounds do they make?

Consider adding several quick sketches in your journal or taking photographs. When you return indoors, take more time to illustrate the birds you observed. Feel free to use a field guide or photograph to help you.

### Literature

Ravens are perhaps the most common bird symbol in the mythologies and religions of ancient cultures. They assume a variety of roles, ranging from messengers of deities and sages to oracles and tricksters. They play a central part in many creation myths and are typically associated with the supernatural realms lying beyond the ordinary experience.

The history of ravens as mythical birds can be traced as far as the 1000-year-old Norse mythology. Odin, the chief god in Norse mythology, had a pair ravens called Hugin and Munin perching on his shoulders. Each morning they were sent out into the world to observe what was happening and question everybody. They would come back by sunrise and whisper to Odin what they had learned. Sometimes Odin himself would turn into a raven.

Hugin and Munin
Fly every day
Over all the world;
I worry for Hugin
That he might not return,
But I worry more for Munin.

Huginn ok Muninn
fljúga hverjan dag
Jörmungrund yfir;
óumk ek of Hugin,
at hann aftr né komi-t,
þó sjámk meir of Munin.

I encourage you to research the symbolism of ravens in a culture of your choice. Here are two of my favorites:

The Raven by Edgar Allan Poe

How Raven Stole the Sun (Native American Myth)

### Art

Ravens have appeared in the mythology of many ancient people. It is no surprise, therefore, that ravens are also popular subjects in art.

I have often been inspired by children’s books. My kids and I will periodically try to recreate the illustrations we enjoy in picture books. I am not alone.

On the website, Native American Art Projects and Lesson Plans, I found two lesson plans centered around children’s books featuring ravens:

A Man Called Raven (Oil Pastel)

How the Raven Stole the Sun (Crayon Batik)

## Exploring Digital Animation with Pixar & Khan Academy

October 5, 20151

STEM has always been a major part of our homeschool curriculum. As my children have gotten older, their interests have only strengthened in relation to math and sciences. They have both expressed an interest in computer programming and we have dabbled a little with different curricula (Homeschool Programming) and online resources (Khan Academy).

In addition to computer programming, my daughter has also become interested in digital animation and graphic art. For Christmas she received a Wacom tablet and has spent many hours learning how to create elaborate graphics. Her work has even won two different t-shirt design contests!

She also loves Japanese anime – some of her favorites are Sword Art Online, Hunter X Hunter, and Fairy Tale. It was no surprise when she expressed interest in learning how to animate her own illustrations.

We were thereby very excited to learn of Pixar in a Box, a collaboration between Pixar Animation Studios and Khan Academy, This free course sponsored by Disney, is a series of video lessons, interactive exercises, and hands-on activities.

The course materials will enable students to discover how the academic concepts they learn in school enable Pixar filmmakers to create new worlds, animate unique characters and tell stories through animation. Although designed especially for students in middle and high school, these resources are available to learners of all ages, completely free of charge.

There are presently six topics in the course:

• Environment Modeling
• Character Modeling
• Animation
• Crowds
• Sets & Staging
• Rendering

Each topic begins with a design focused lesson that doesn’t require math concepts beyond the elementary level. The goal is for people of all ages try these lessons – to first get you creating things with interactive tools while exposing the connections to mathematics.

The second lesson dives deeper into the concepts involved and are designed to increase in difficulty so that students can attempt more advanced material. Each lesson is designed to take approximately one hour to complete and includes hands-on activities to extend the lesson.

What I love best about Khan Academy is that the course material is self-paced. We can pick up a lesson at any time and work through the material at a pace with which we are comfortable. There is no deadline and thereby no pressure.

We look forward to integrating this course into our curriculum more fully in the near future. She’s already begun a story board for an animated show of her own.

## Encouraging Student Passions with DK Books

September 10, 2015

From fly tying and whips to architecture and Lego, passion projects don’t just provide educational value, they fuel students to take control of their education.

Passion Projects, or how we have come to refer to the independent study projects that my children have pursued over the years, are an excellent opportunity for middle and high school students to invest in themselves.

Many thanks to DK Publishing for providing these books to us for review. Please see my full Disclosure Policy for more details.

Passion Projects build a sense of ownership, improve communication skills, help develop research skills, and encourage entrepreneurship. It is not unusual for children to also have a variety of interests.

My son, for example, is passionate about Lego, Minecraft, aeronautics (as well as container ships and trains), and music. Some weeks he will devote his leisure time solely to music theory and composition. The following week, he’ll move on to Lego and spend hours building models and redesigning his Lego city.

This summer, I wanted to find a book for each of my children that not only complemented their interests but also really inspired them to take their passion projects to the next level. DK Books provides a wonderful selection of books providing inspiration to middle and high school students.

### Lego Architecture: The Visual Guide

For my son, I selected LEGO Architecture: the Visual Guide by Philip Wilkinson. The book comes in an extremely durable slipcover with glossy matte finish and Lego artwork.

Each of the twenty-two offerings in the Lego Architecture line get their own section. Each also includes interesting information about the design and  many photographs of the complete piece, each from different angles. Footnotes provide additional tidbits about the design process.

You also get photos of the real architectural structure the Lego set was patterned after. There is a side by side comparison of the real thing with the Lego version, and also a history of the building and its chief designer(s).

My son has poured over this book for hours on multiple occasions. He shared, “Mom, this book is really cool. It helps me get an idea for how I want to design my Lego city buildings.”

## Sketch Book for the Artist

For my daughter, I selected Sketch Book for the Artist by Sarah Simblet. My daughter has always been interested in art and in recent months has devoted considerable time to improving her drawing skills. She has watched video tutorials on YouTube, taken online illustration classes, and worked diligently in her own sketch books.

She has been delighted with Sketch Book for the Artist. The book shows many of the author’s works and is also beautifully illustrated with inspirational and exemplary works by significant artists from the Reniassance to the current era.

A variety of mediums including pencil (graphite), pen and ink, chalk, etc. are well represented. The reproductions are great and help create new ideas and directions. The author also gives tips as well as suggested exercises for improving your own skills.

### Getting Started

Passion Projects work well in a public or private school classroom as well. Here, students are asked to complete a mini-research project on the topic of their choice and are given an hour each school day to work on their projects. This hour is sometimes referred to as the Genius Hour. Because the topics are selected by the students, they truly enjoy the research process and presenting their findings.

• What do you want to know more about or learn how to do?
• How does that passion inspire you when things are tough?
• In what ways can your passion inspire others? Who do you want to help?

### Encouraging Student Passions with DK Books

Whatever topic your child chooses to pursue, you’ll surely find resources and books from DK Publishing. Whether their interests are related to art, cooking, or super heroes, you’ll surely find something for everyone.

## Jumping into National History Day

August 25, 2015

I love history! My favorite books are all historical fiction. Had I not pursued a degree in science – I likely would have considered a career in history.

History, as a school subject, is often overlooked in the elementary years (with the exception of a few isolated unit studies). As a homeschool mom, I am blessed to be able to immerse my children in a comprehensive and chronological study of history.

When we first started homeschooling, we had the opportunity to volunteer at the High Desert Museum in Bend, Oregon as living history interpreters. It was an amazing experience living and homeschooling in 1880.

In addition to reading about history, initially in the four volume series by Susan Wise Bauer, Story of the World and now in her series for older readers, The History of the Ancient World, we enjoy a variety of research projects, timelines, hands-on activities, and field trips around the world. One of our favorite annual experiences is a living wax museum.

I have written previously about our experiences in Bringing History to Life and the Collision of Art & Literary History. We have had a lot of fun over the years and have learned a great deal not just about the historical characters we have researched, but also about public speaking, goal setting, and historical re-enactments.

In all the years we have been engaged in these long-term history projects, I have had a little whisper in my ear to take it to the next level through participation in National History Day. National History Day began in April 1974 – an idea of history professor David Van Tassel, who was worried about the decline of the humanities in general and history in particular in America’s schools.

Van Tassel was particularly distressed by the boring rote memorization he saw in most history classrooms.  He wanted to reinvigorate the teaching and learning of history.

Today, National History Day contests are taking place in every state. Providing a learning adventure that teaches critical thinking, writing and research skills and boosts performance across all subjects – not just history.

Every year National History Day frames students’ research within a historical theme. The theme is chosen for the broad application to world, national, or state history and its relevance to ancient history or to the more recent past. This year’s theme is Exploration, Encounter, Exchange in History.

The theme provides an opportunity for students to push past the antiquated view of history as mere facts and dates. It encourages students to use critical thinking skills to dive into historical content and thereby develop perspective and understanding.

We will be participating for in the National History Day contest for the first time this academic year. I’ll be coordinating the contest for the Southern Oregon coast and sharing our progress along the way.

I want to encourage you to join us. The NHD website provides an incredible array of lesson materials and curriculum to help you get started.
