I know when I give an answer like goofymom23 it is more of a play on words or negative responses I get for homeschooling... ie "why wouldn't you send them to PS and just suplement at home, after all the PS can offer so much that you can not". Another is "People only homeschool because they are too lazy to get up in the mornings". My answer is "yep, it is much easier to sleep until 9 and teach my kids for 7 hours, than it is to spend 30 min to get ride of them every morning at 6:45".
One reaction that the poster would never explain here on the DIS was "your child will never get to look through a prism in science".
Well my kids actually just studied the way chlorophyll affects light. They studied the light spectrum through a spectroscope they built and then looked at the color spectrum while filtering the light through a vial of chlorophyll (even made that, fill a jar with spinach and cover with alcohol, let sit for 3 days). The spectroscope was from a poster from NASA. I can't find the link I used right now for the free poster, but NASA has a lot of free science materials. I also have a Free NASA Earth Science curriculum that I will use once we finish the Jason Project.
