Daryl Science

Here's another site that takes some sorting through, but has some treasures to be found. I was fortunate enough to attend a couple of workshops presented by Daryl, which were loaded with great demo ideas for science classes. He's a high school physics teacher, so the bulk of his things are geared to that set, but many are appropriate/adaptable to younger students and he's tried to add some demos for other branches of science. In order to get to the demos, you have to do a bit of navigating on the site... on the top left of the home page, click on "Professional Stuff", then on "Science Teacher Demos". There's a lot of other good stuff to look through while you're at the site, so spend some time there.

When I've had questions about some of his demos - things I saw in person or found on the site - I found Daryl to be very responsive to emails (his address can be found on the site). That said, I'm not sure if he's regularly updating his site anymore and if that's still the case, but I suspect that if he gets your question, he'll answer it to the best of his ability.

A warning of sorts.... he's got a sense of humor... some of us appreciate it, others have to wade through it. Regardless of whether or not you find him funny, he knows physics and has solid activities.
