Carl is feeling much better, but I have to keep him home today too.
I am looking for projects for him for Earth Day. I have found a site with a lot of good ideas:
I used it last time Carl was on recovery day – looking for projects that have something to do with topics of study that week and to keep me from going crazy.
Last time he was sick, I found some great pages (on dltk and on other sites) for the letter X. Besides Xray and Xylophone, we learned about Xenops (a south american bird) and Xiphias (a swordfish).
