I'm not officially decided on science for this year. I'm considering Christian Kids Explore Physics. We did Christian Kids Explore Earth and Space last year and really had a lot of fun with it. I'm considering Apologia's Biology course for Kelsea.
The boys will be starting Latina Christiana I this year to round out a classic education. Kelsea prefers to learn Spanish, so she'll be using Switched on Schoolhouse's Spanish cd-rom.
