He explored the differences between thin and thick layers of ice and how they are formed. We appreciated the beauty of Jack Frost at work.
When we returned home he did some work with A+tutorsoft math. This is a new math program that we are testing out. So far the lad is saying "but I know this mom". So we are skipping lessons and going to test areas to see what he knows and what needs to be fine tuned a bit. Generally though the lad has an appreciation for the format so I think it will work for him.
What else....OH.. our homeschool group has a lego competition in about a month and so the lad's busy making an entry for it. He's quite enthused. He's really hoping that the judges will like it. Personally I think he's done an excellent job coming up with the idea and building it without any assistance.
