Forces and Motion TV


EI TV - Educational Innovations BlogNo matter what grade you teach, at some point you will surely need to introduce your students to the three Laws of Motion developed by Sir Isaac Newton in 1687.  His Philosophiae Naturalis Principia Mathematica took Newton two years to write and was the culmination of more than 20 years of thinking.

That was more than 300 years ago.  Today, we live in the YouTube era.  Videos allow us to quickly summarize important scientific concepts like forces and motion in dramatic ways that your students will understand and remember.  We’ve gathered some excellent examples here.  Enjoy!  

If you find a video on forces and motion that you’d like to share with us, please leave a comment!

Forces and Motion in the News


latino-professor-newspaperYou can’t talk about forces and motion without talking about Isaac Newton.  His three Laws of Motion were published more than 300 years ago, and yet their basic concepts—inertia, acceleration, momentum, and mass—are still the standard for how we discuss forces and motion today.  The laws may have been refined over the years (most famously by Einstein) but they still reign as incontrovertible scientific laws.  We couldn’t send the Hubble Space Telescope into orbit without Newton.

While there may not be much NEW about Newton’s Laws, there is still plenty to say about how they affect the world around us.  Read on for some interesting news reports related to forces and motion.  Let us know if you find an article you’d like us to post!

Using Growing Spheres for 3D Modeling


Using Growing Spheres for 3D Modeling - Educational Innovations Blogby Jen Donaldson

In my classroom, I’ve devised two new uses for Growing Spheres which help students have a better grasp on some otherwise complicated science concepts.  

These small spheres are a wonderful way to make the invisible VISIBLE—in three dimensions!

The Chemistry of Currency


Dr. Kenneth Lyle, Duke University Department of Chemistryby Gabrielle Hodgins and Dr. Kenneth Lyle, Duke University, Durham NC

The wonders of magnetic ink!

INTRODUCTION

Demonstrating the magnetic ink used in printing US currency has proven to engage audiences of all ages because of its relevance to everyday life.  Nearly everyone has used machines that distribute and/or accept currency but few understand how the machines distinguish between the various denominations.  The key is in the face of each denomination.  Magnetic ink is used in the printing of the currency.  Each denomination has a different face and, therefore, a different magnetic signature.  Similar to a bar code reader, the machines recognize the denomination by its magnetic signature.  A strong magnet, such as a neodymium magnet, can be used to demonstrate the magnetic character of US currency.
