IT’S A JETSONS WORLD by Jeffrey Tucker (PDF ebook)

Today we feature this fascinating economics book, just published by the Mises Institute book for junior high – adult readers on how free market has changed our lives today,  particularly in the digital universe, and yet we don’t appreciate or realize this nearly enough. Meanwhile, the public (government) sector is systematically wrecking the physical world in sneaky and petty ways that really do matter.
Easy to read, full of great stories, and written with an Austrian School of economics viewpoint, this book is and eye-opener for older students and parents who want to gain a better understanding on the changes in our world today and in the years ahead.

The pace of change is mind-boggling. The world is being reinvented in our lifetimes, every day. Email has only been mainstream for 15 years or so, and young people now regard it as a dated form of communication used only for the most formal correspondence. Today young people are brief instant messaging through social media, but that’s only for now, and who knows what next year will bring.
Oddly, hardly anyone seems to care, and even fewer care about the institutional force that makes all this possible, which is the market economy. Instead, we just adjust to the new reality. We even hear of the grave problem of “miracle fatigue”—too much great stuff, too often. Truly, this new world seems to have arrived without much fanfare at all.

The Jetsons’ world is our world: explosive technological advances, entrenched bourgeois culture, a culture of enterprise that is the very font of the good life. But there is one major difference, and it isn’t the flying car, which we might already have were it not for the government’s promotion of roads and the central plan that manages transportation. It is this: we also live in the midst of a gigantic leviathan state that seeks to control every aspect of our life to its smallest detail.

The government, however, is still the Flintstones, an anachronism that operates as this massive drag on our lives. With its money manipulations, regulations, taxation, wars (on people, products, and services), prisons, and injustices, we similarly look the other way. We try to find the workaround and keep living like the Jetsons.

THE THEOLOGY OF CALVIN & HOBBES

Well, not quite… but today we feature something completely different: Here from the Experimental Theology blog is a playful and thoughtful “young-reader friendly” online book of theology lessons derived from none other than Calvin & Hobbes. “How can this possibly be?” you ask. Well, give it a look-see. Regardless of your theological persuasion, this contains some fascinating material (AND great cartoons) for young and old readers alike.

THE MEGA PENNY PROJECT

Visualizing huge numbers can be very difficult. People regularly talk about millions of miles, billions of bytes, or trillions of dollars, yet it’s still hard to grasp just how much a “billion” really is.
The MegaPenny Project aims to help by taking one small everyday item, the U.S. penny, and building on that to answer the question: “What would a billion (or a trillion) pennies look like?”

THE HUMAN HEART

Did you know that the human heart beats about 100,000 times a day, 35 million times a year, and two and a half billion times in an average lifetime?
Did you know that, on any given day, your heart beats roughly 100,000 times and your blood travels about 12,000 miles as it circulates throughout your body?
Did you know the average heart pumps more that a gallon of blood a minute?
Did you know a kid’s heart is about the size of a fist… and an adult’s heart is the size of two fists?

Here is a great collection of links from “Education World” all about the human heart. You’ll learn how the heart works, take an interactive tour of the heart, learn about the heart’s electrical system, blood flow and blood supply, see some amazing videos, and much more.

HANG OUT WITH BATS!

BatsLive is a virtual field trip into the amazing world of bats! The site contains dozens of interactive resources, including video tours, lesson plans, webinars, and printable resources about bats. Here’s their introduction to this extensive and well-done resource site:

Bats are vital to healthy ecosystems and human economies worldwide. As primary predators of night-flying insects, bats consume enormous quantities of agricultural pests and reduce the need for chemical pesticides. Yet these wonderfully diverse and beneficial creatures are among the least studied and most misunderstood of animals. Bats are threatened worldwide, and their colonies and habitats are destroyed – both intentionally and inadvertently – because of myths, misinformation, and lack of scientific knowledge and understanding. Bat populations are declining almost everywhere in North America especially due to the devastating White-nose Syndrome. Losing bats has far-reaching consequences for natural ecosystems and human economies. Knowledge is the key to their conservation and protection.

BatsLIVE: A Distance Learning Adventure is an exciting, free education program for children in the 4-8th grades and their educators, that will bring bat conservation to life in your classroom or community.

SIMPLE MACHINES NOTEBOOKING PAGES

Betsy at NotebookingNook.com has put together this neat little resource page on some of the “simple machines” we use every single day, but hardly even think about. Here’s what she says about it:

In the past, when we have studied simple machines, I found it easy to find information on this topic but not as simple to find good free resources. My son and I had an occasion to discuss simple machines this week and I remembered how difficult it was to find what I needed once upon a time and thought I’d put something together for any of you looking for something on this topic. I hope this helps.

Included in her PDF download are: Notebooking pages & matchbooks for levers, wheel & axle, the pulley, inclined plane, wedges and screws.
Also on the page are links to 5 short, simple online videos explaining and demonstrating how these “simple machines” work.

LEGO BALLOON CAR PROJECT

Okay, LEGO builders. Here’s today’s engineering challenge for you: Can you build a LEGO car that zooms across the floor that uses a balloon as its engine/source of power? All you should use for this project are LEGO parts, LEGO wheels if you have them, and a balloon.

There’s no one “right” way to do this, but you might keep in mind:
Which way the balloon opens
Horizontal to vertical stability
Balloon staying away from tires

Try to invent your own working Balloon Car first… and then, if you get finished, or stuck, or are ready to see how some other students did it and solved their own “engineering” problems, you can click the link below:

Rather than burden students with morphological technicalities right off the bat, the pupil will learn Greek grammar in the same way he learned his mother tongue; in context and as the need arises.

Here’s a complete 30 lesson spelling course especially designed for students grades 6 to 8, with a complete course outline, lesson plans, dictation, answer key, and more. Good stuff!

Says the author, Marie Rackham:

“Spelling, like grammar and punctuation, is a technique of English.  Spelling is an important communication skill. In my opinion, since the advent of the Internet, it is even more important because words on a web page may determine what people think of you and your abilities. Spelling, grammar, and punctuation errors will make you appear less credible to your audience. Good luck and have fun with the course!”

FREEBIE FRIDAY ROUNDUP: BALLOONS, ART, CIVICS & CLASSICS

Since our server crash a while back killed off our archives, we are re-posting a handfull of past freebie links every Friday for the forseeable future. In other words, it’s time for another “Freebie Friday Roundup!” Here’s this week’s goodies:

MAKE YOUR OWN BALLOON ANIMALS!

You just KNOW somebody in your household needs to know how to make some cool balloon animals this summer. It occurs to me that a nice stock of balloons from the local party store along with these links would sure keep ’em occupied for a long while. And who knows? They might be a big hit at your next party or get-together.

And below is a great site with dozens of well-illustrated tutorials on how to make your own balloon animal sculptures… from very basic shapes to crazy, intricate creations. Have fun!

i-CIVICS

iCivics is chock full of interactive games, curriculum and lesson plans for teaching young people more about civics… and it’s all free! Here’s what they say about their mission on the site:

There is an important link between civic knowledge and civic engagement. Our system thrives if Americans understand how our government and its branches work. In fact, our public schools were founded to teach young people to understand these structures, and to cultivate informed citizens. Yet students are growing up in an uncivic-minded era. Civic education has nearly disappeared from the school curriculum. More than ever, youth are not voting and are becoming disillusioned with the political process. This is why, after serving 25 years on the bench of the Supreme Court, Justice Sandra Day O’Connor founded iCivics in 2009: to restore civic education in our nation’s schools.

The success of any democratic system depends on the active participation of its citizens. iCivics gives students the necessary tools to learn about and participate in civic life, and teachers the materials and support to achieve this goal. Our free resources include print-and-go lesson plans, interactive digital tools, and award-winning games.

iCivics teaches students how government works by having them experience it directly. Through our games, the player steps into any role – a judge, a member of Congress, a community activist fighting for local change, even the President of the United States – and does the job they do. Educational video games allow for concepts to happen to us. They convey information while teaching skills for effective civic engagement.

Your tweens and teens may get a kick out of following along and deciphering these humorous 1 minute summaries of these famous stories. Along with partners Jim Becker and Andy Mayer, John “Mighty Mouth” Moschitta recorded a pugnacious take on ten classic novels in which he summarizes each book’s entire story in approximately one minute. Included in this collection, entitled Ten Classics in Ten Minutes, are Herman Melville’s Moby Dick; William Shakespeare’s Romeo and Juliet; F Scott Fitzgerald’s The Great Gatsby; Margaret Mitchell’s Gone with the Wind; and John Steinbeck’s The Grapes of Wrath.

Yep, this resource is really just for the fun of it, but students will also at least get a notion of what these classic stories are about. If you want to have some fun with these and see if your student actually listens, have your student tell YOU what the story is about after watching one of these videos. Then try it with someone else in the family (mom, dad, siblings, etc.).
