The Power of Electricity, Magnetism… and Infomercials!


Educational Innovations BlogBy Cathy Byrne

Virtually all fourth grade students explore electricity and magnetism.  As part of this unit, students are asked to do two things:

1 –   Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents (4-PS3-2)

2 –   Apply scientific ideas to design, test, and refine a device that converts energy from one form to another (4-PS3-4). 

This year, the teachers at my school put a new twist on our electricity and magnetism unit… and the results were amazing!

Fidget Spinners, Physics, and Sir Isaac Newton


by Ted BeyerTed Beyer, Educational Innovations, Inc.

Fidget spinners are the latest fad to sweep, seemingly, the world. Love them or hate them, they are everywhere—on playgrounds, in backyards, living rooms, and even schools, although many schools have banned them as being distractions.  But wait just a minute here!  For once, let’s see if we can’t use a fad to teach something.  You see, there is actually a fair bit of science lurking in those spinney things.

Join Our Elementary Science Club Today!


Tami O'Connorby Tami G. O’Connor

As elementary school teachers, we aim to help our students become scientifically literate (among many other things).  But let’s face it:  too often we have limited time for science instruction during the school day.  Still, we know that kids just love science!  They’re always eager to learn more about the world around them, especially when they’re having fun while they’re learning.

But what can we do when our science teaching time is so limited in school?  How do you get students involved in scientific discovery outside the classroom?  Sure, you can give them homework, but many kids find simply reading about science unappealing.  You want your students to LOVE learning more about science… not dread it.

Classroom Fun with the Static Electricity Electroscope


Educational Innovations Blogby Nancy Foote

The latest addition to my classroom’s Curiosity Table is a Static Electricity Electroscope.  The fact that it looks a bit odd made it even more intriguing to my students.  Once they began to play with the electroscope, they couldn’t stop. Read the rest of this entry »


The Chemistry of Currency

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.
