There are three &#8220;standard&#8221; middle-school science courses: life science (introductory biology; usually grade 6 or 7), earth science (or earth &amp; space science; usually grade 7 or 8), and physical science (introductory chemistry and physics; usually grade 8 or 9). Many homeschool parents try to cover all three of these courses in two years, grades 7 and 8, leaving grade 9 available for a first high school level science course. Traditionally that&#8217;s been first-year high school biology, with first-year high school chemistry in grade 10, but increasingly homeschoolers (and many public schools) are swapping those, teaching first-year chemistry in grade 9 and first-year biology in grade 10. That&#8217;s because modern biology courses are increasingly taught bottom-up&#8211;starting with the chemistry of life, life processes, cellular chemistry, and so on&#8211;rather than the old top-down approach of starting with organisms and working down toward cell-level issues.<br \/>\n<\/span><\/p>\n<p><span style=\"font-family: Arial;\">We&#8217;re already planning to introduce separate kits for each of those three courses, starting with life science, but I realized that there are likely to be enough materials in common in those three kits that it might make sense to also offer a consolidated kit that would include the equipment and chemicals to do all three courses. It&#8217;d be a relatively expensive kit, but not as expensive as the three separate kits. If we do decide to offer a consolidated kit, it&#8217;d be a 2014 or even 2015 product, but it makes sense to think about it now because it would effect how we design the three separate kits.<br \/>\n<\/span><\/p>\n<p><span style=\"font-family: Arial;\">And, on that note, I think I&#8217;ll make up a liter of universal indicator solution today, because that&#8217;s one of the chemicals that would probably be in the kit and I haven&#8217;t used it in probably 40 years. The stuff is <a href=\"http:\/\/www.sciencelab.com\/page\/S\/PVAR\/SLU1051\">ridiculously expensive to buy<\/a>, but considerably less so to make.<br \/>\n<\/span><\/p>\n<hr style=\"width: 65%; height: 3px; font-family: Arial;\" \/>\n<p><span style=\"font-weight: bold; color: #000099; font-family: Arial;\">11:49 &#8211;<\/span><span style=\"font-family: Arial;\"> I thought this was interesting. Apparently, <a href=\"http:\/\/www.cnn.com\/2013\/02\/28\/us\/guam-snake-drugs\/index.html?hpt=hp_t2\">acetaminophen is even more toxic to snakes than it is to people<\/a>. That&#8217;s pretty damned toxic, considering that something like 50,000 Americans a year are treated in emergency rooms for acetaminophen poisoning and about 500 of them die.<br \/>\n<\/span><\/p>\n<hr style=\"width: 65%; height: 3px; font-family: Arial;\" \/>\n<p><span style=\"font-weight: bold; color: #000099; font-family: Arial;\">14:02 &#8211;<\/span><span style=\"font-family: Arial;\"> I have finally had enough of being spammed by Shapeways. I was surprised that they spam, because they&#8217;re supposed to be a community effort in the MAKER tradition. But they&#8217;ve been spamming me for two or three years now. I have clicked on the unsubscribe link many, many times. I have sent them email. But the spams just keep on coming. So finally I went to their customer service page and left the following.<\/span><\/p>\n<blockquote><p>What do I have to do to get you to stop spamming me? I bought one item from you (a Dremelfuge centrifuge head) two or three years ago, and you have been spamming me ever since. I never &#8220;joined&#8221; your community, nor did I ever give you permission to email me.<\/p>\n<p>So, please take me off your mailing list immediately. I should tell you that I&#8217;m an O&#8217;Reilly\/MAKE author, and if you keep spamming me I&#8217;m going to do everything I can to make sure my readers are aware that I consider your company&#8217;s business practices unacceptable.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>08:56 &#8211; Colin let me sleep in this morning.
