Rube Goldberg

Posted by tigerhawkvok on July 29, 2009 19:59 in lhs , teaching

So for the past month or so I've been teaching summer camps again at the Lawrence Hall of Science, and I thought I'd put up last week's group's final Rube Goldberg project with the Lego Mindstorms kit:

They got really close, and if they had 30 more minutes I think they could have pulled it off, but getting that far in about 5 hours total is pretty impressive.

On an aside, for anyone that wants to embed YouTube code that doesn't use that pesky, invalid "<embed>" tag:

<object width="500" height="405" data='EMBED_URL' type="application/x-shockwave-flash">
<param name="movie" value="EMBED_URL_AGAIN"></param>
<param name="allowFullScreen" value="true"></param>
<param name="allowscriptaccess" value="always"></param>
</object>

Remember to escape ampersands (&) in the URL with "&amp;". This method is verified to work on Safari, Firefox, Chrome, IE6+, and Opera.

Credentialed

Posted by tigerhawkvok on February 18, 2009 14:21 in teaching

Nice — finally, after three months, I am a credentialed substitute teacher!

In addition to providing a source of income, this will let me gain teaching hours needed if I want to get a regular teaching credential, as well. Now, I just have to submit myself to the county of Alameda / city of Berkeley ....

I'll try to get up a post about science later today, particularly as I rather egregiously didn't post for Darwin Day, then I'll post a bit about black holes by Friday in honor / celebration of a talk I'll be giving to the Tri-Valley Stargazers.

I leave you with the brilliance of Randall Munroe:
