We still have friends over for science on Wednesdays; although, I am not as consistent as I used to be. Sometimes we invite everyone; sometimes just one; sometimes we go over to Katy's and do it over there. On average we're spending an hour to 90 minutes on the subject. We are about to embark on the Solar System and most likely finish the year studying about rocks and minerals. The kids will most likely remember Wednesdays though running around outside with their friends and cousins rather than sitting around the table doing experiments and writing glossary words.
