When I was in high school, I remember friends who were jealous that my parents knew math and science – since obviously that meant I could ask them for help with my homework. What my friends didn’t know was that my parents treated the most straightforward question as an invitation to a freewheeling Socratic dialogue of no less than 30 minutes. While I would have been happy just to finish my assignment with time to watch some TV, my parents wanted me to understand how things worked. Isn’t it funny how we do to our kids the very things our…

pH – A SCIENCE CREATIVE QUARTERLY PIN UP (NO. 2)
(CLICK HERE FOR PIN-UP POSTER – pdf file ~140k) – We suggest photocopying at 129% – LTR to 11×17 – Metric: pH Range: 0-14 (no units) Measures: Degree of acidity or alkalinity. It is a logarithmic scale expressing the concentration of Hydrogen ions in solution. pH = -log10 [H+] A solution is “acidic” if pH is less than 7 (Hydrogen ion concentration is greater than 10−7 M), “neutral” if pH equals 7 (Hydrogen ion concentration equals 10−7 M), and “alkaline” if pH greater than 7 (Hydrogen ion concentration is less than 10−7 M). As was pointed out here, pH measures…
AFRICAN LION FAMILY OBJECTS TO THEIR PORTRAYAL IN RECENT DISCOVERY CHANNEL DOCUMENTARY
(Last week was reading week at UBC, but we were so freaking busy that we didn’t even get a chance to rest. Therefore, this week we get to catch up on our sleep by reprinting some of our finest. Enjoy.) – FROM THE ARCHIVE – Papa Lion (Carl) First off, that tree we were lying around in the shade by, that wasn’t even our tree. The producers literally brought in that tree and told us it was going to be our new tree. They said our tree—the tree we’ve lay under for years—“didn’t have a river view” and was “a…
