Center of Mass Challenge


By Jeremy Johnson

In my 13 years of classroom teaching experience, I’ve learned a few tricks to keep my students from becoming overwhelmed—or bored—by their science textbooks.  One of my favorite tricks is to get my kids up on their feet, doing science instead of reading about it.

When I teach about gravity and center of mass, for example, I like to shake things up by turning our classroom into an impromptu biokinetics lab.  I challenge my students to perform a series of seemingly simple physical tests, described below.  Lift a chair?  Raise your leg?  Pick up a quarter?  No problem!  (Or so they think…)

First Graders and the Drinking Bird: A Love Story


First Graders & the Drinking Bird: A Love Story - Educational Innovations Blogby John Frassinelli

Having first seen a “drinking bird” in elementary school myself, I had never forgotten it.  Our teacher, I think, had placed one on the windowsill.  We had no air conditioning in those days, and the windows actually opened!  Air circulated through the room, and that probably influenced the bird.  I think it’s too bad that many classrooms are hermetically sealed these days, but we do what we can.

Recently I decided to introduce my first graders to my old friend, the Drinking Bird.   I bought a few birds and fooled around with them, making sure each one would “drink” as it was supposed to.  I learned that some birds need a bit of adjustment—their centers of mass might be too high or too low.  But this is easily remedied by gently twisting the bird’s body and raising (or lowering) it on its metal clasp.

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 »


Engaging Students with Electrochemistry… and Goldenrod Paper


Educational Innovations Blogby Nancy Foote

I’m in love with goldenrod paper.  I’ve loved it for a long time.  In my never-ending quest to emotionally entangle my students in the content of our science curriculum, Color-Changing Goldenrod Paper provides a long-lasting entanglement.

If you’ve never done the bloody handprint goldenrod paper demo with your students, you are truly missing out—and so are they)!  This is the most engaging “engage” part of the 5 E’s I’ve ever experienced.  I like to do the bloody handprint demo around Halloween, but we don’t do acid/base chemistry until February.  That’s a long time to wonder, ponder and try to figure out exactly what is happening.  But that’s for another blog post.

Having a Blast with Articulating Stomp Rockets


Articulating Stomp Rockets - Educational Innovations Blog

by Paul Reyna

Have you ever had a science activity or demonstration that you really liked to do with your students, but then were told you could not do it anymore—or it did not fit your curriculum?

That is exactly what happened to me a few years ago.
