Science activities for Halloween!

October 27, 2009

With halloween fast approaching, it’s time to take advantage of a frivolous holiday to do some fun science stuff. No post about Halloween would be complete without a reference to the Grossology site. Scroll down for  “lab activities”:  This gets high marks from one teacher who says, “It has the simpliest of the slimey things, […]

Science, art, and Bay Area culture

October 12, 2009

One of the things that I miss most about the Bay Area is the intensive culture of geekery and delightful playfulness that goes with the unabashed celebration of membership in the pocket protector set.  I invited Alan Rorie — an artist and a scientist at the Exploratorium (who happens to hold my old job) — […]

If a boy pees on the floor and there’s nobody there to see it

September 26, 2009

We see the darndest questions on teacher listservs. It seems that, at one school, there was a mystery to be solved. The boys’ urinals were often surrounded by a puddle of “liquid.” Were the urinals weeping water? Or were the boys purposely urinating on the floor (as the janitor believed)? And, most importantly, how can […]

The inner life of the cell

September 24, 2009

I was recently reminded of this wonderful visualization of the processes inside the cell.  As a physicist, I found this quite powerful in imagining this mysterious (and usually, to me, boring) microscopic world.  It was created by a Harvard professor in conjunction with a scientific animation company.  Here’s the video: In my art and science […]

A couple of beautiful things – Science and images

September 10, 2009

I’m in a scientific visualization seminar now, so I’ll probably be sharing some beautiful things with some regularity. There is something very satisfying about complex geometrical objects.  I think my brain feels this sigh of relief at such orderly intricacies.  So, I love these images created by computer algorithm, basically tweaking parameters to get surprising […]

Enriching the intellectual life of teachers

August 27, 2009

This post is based on ideas from a presentation by Rachel Scherr of the University of Maryland and Seattle Pacific University. Teachers, Rachel says, are disenfranchised.  Just as students who have no voice in what and how they learn in the classroom, professional development is often inflicted upon teachers who have no voice in the […]

Engineers Make Art: Visualizing Fluid Flow

August 20, 2009

Our most famous fluids tend to be transparent — air and water, for example.  This makes it hard for us to imagine how fluids are moving as members of the general public, but also poses an interesting problem for budding engineers.  They need to know how to make fluids do what they want them to […]

Hands on Science Sunday: Feeling pressured?

May 31, 2009

Here’s today’s science classroom activity.  We’re surrounded by the crushing weight of layers of atmosphere above us, but we don’t feel it.  Why?  Our perception is tuned to differences, not absolutes.  If we were in a completely pink world, we would notice anything that wasn’t pink, but (I’m pretty sure) after a few minutes, we […]

Exchange of scientific ideas

December 17, 2008

I just read this lovely discussion of how a more open scientific culture (think open-access science) could improve the collective memory of science. This was on the Back Page of APS News (subscribers only) and here is the author Michael Nielsen’s blog post about the topic too, with some additional information. His basic premise is […]

Ask a science education question

December 2, 2008

I just found out about a neat free service for science educators.  It’s mostly for those in Colorado, but those outside Colorado are welcome to use it as well.  It’s a free email servicer for teachers to ask questions directly of a science education expert, who will go out and find the answer for you.  […]

Myth: Dang. Looks like Gingko doesn’t work.

November 25, 2008

Just got this from Bob Park’s What’s New column. Looks like Gingko has failed a double-blind study to see if it really improves memory. I’ve been taking it for a while, in hopes that it would defuzz my neuronal connections (I’m not that old, but my memory took a real hit ever since I was […]
