A common search carried out by sciencebase visitors is “Phylum Arthropoda”. Innocent enough, of course, there are bound to be lots of followers of the site interested in insects, arachnids, and crustaceans.
Anyway, the best starting point to get plenty more info on the arthropods is, as usual, Wikipedia. But, if you’re after science lessons on arthropods then check out the K5 science lesson plans page and follow the link to the Columbia Education Center in Portland, Oregon, to get to the specific listings. If you’ve got a particular creature in which you’re interested, please use the sciencebase search box top right, we can’t guarantee that you’ll find what you’re looking for among the sciencebase pages themselves but there are usually other links on the site you can follow to find out more.
