Germs in the News


Whether it’s the Ebola virus or more commonplace “bugs,” we often hear about germs in the news.  Check out this selection of noteworthy news items.


Good Morning America goes into a classroom to see how quickly germs can spread.  (Our Glo-Germ powder makes a cameo appearance!)

In November 2014, Dutch researchers reported that 10 seconds of kissing can translate into 80 million germs moving from one person to the other.

What’s the Weather? Check Your Weatherglass Barometer


Ted Beyer, Educational Innovations

by Ted Beyer

Predicting the weather is an age-old guessing game.

Over time, more and more sophisticated devices have been developed to aid in the guessing game.  Indeed, some of the largest computers in the world today are dedicated to modeling the weather using millions of data points collected all over the world—all in an effort to determine if going to the beach this weekend is a good idea, or if you should just stay home and binge watch Game of Thrones (again).

Weatherglass BarometerAfter temperature, one of the earliest scientific observations about the weather is the variation in barometric pressure.  Local changes in air pressure usually signal changes in the weather.  Falling pressure generally indicates rain, snow or wind storms, and increasing pressure most often indicates nicer weather.

One of the earliest gadgets used to try and track barometric pressure was the Weather Glass, also known as the Goethe Barometer [1].   Evangelista Toricelli [2] came up with the first truly accurate barometer—the classic, mercury-filled device—sometime around 1643-44.  [Note: Educational Innovations has a mercury-free version of this Science classroom “must-have.”] Read the rest of this entry »


A Firsthand Lesson on Colds, Flu & Infectious Disease


Priscilla Robinson, Educational Innovationsby:  Priscilla Robinson

Talking about Infectious Disease

These days, it’s hard not to hear reports about the spread of infectious disease, from serious viruses like Ebola to the “common” cold.  There are ads for flu shots and cold remedies, nightly media coverage about rampant epidemics all over the world, and pundits predicting whether these contagious diseases might someday get to this country.

So how is this affecting your students?  Are they asking questions?  Are they anxious about where these germs may be lurking, and whether they or their families are in any danger?

As a teacher, I’ve found that the science classroom is the perfect environment to help students understand the world around them.

A few years ago, my students and I survived an outbreak of the Swine Flu.  So many kids were getting sick that our school had to establish a quarantine room to isolate ill students until their parents could pick them up.  During this time, I set up stringent hand-washing techniques for students (and myself), as well as protocols for disinfecting desks, chairs and door handles.  Ultimately, my students had a lower rate of absences than their peers, and I stayed healthy as well.

Below you’ll find two fun and engaging classroom activities related to infectious disease transmission and prevention.  Try them with your students! Read the rest of this entry »

What It Means to Be a Teacher

If you’re reading this, chances are you’re a teacher.

If you spend more than an hour a day with kids—from 1 to 100 (in age and quantity)—chances are you’re a teacher.

If you’ve grinned at our Facebook comics or said “I need that!” while clicking through our website, chances are you’re a teacher.

But what is a teacher?

Here’s what the dictionary says:
