Have you met The Happy Scientist? Robert Krampf is a former museum geologist and instructor turned science showman. His special million-volt tesla coil is the star of his traveling show, and he has taken his show all over the country, including the Discovery Channel and David Letterman. You don't have to travel to see Krampf light up the stage, however. His site, The Happy Scientist, delivers online science lessons right to your computer. Divided by subject matter and also organized by state science standards, the videos and experiments on this site are kid-friendly and homeschooler-approved. Let your science-happy homeschooler off the leash in this site and be prepared to lose them for hours. Here are some links to just a few of his free videos. Members have access to all the content on the site, including many special members-only areas and features, and membership is only $20/year.
Checking the science photo of the day every day is a great way to integrate science into your homeschool schedule in a fun way that will expose your child to a ton of different topics and ideas without overwhelming them in reading. It's always something to think about, but sometimes will spark a train of thought or inquiry that will take your child deeper into a specific topic. Who knows where it might lead?
