Wow, we only had BTT two times this week! Thursday was the Ontario Science Centre trip, and on Friday it was a Day 2. Speaking of the Science Centre trip, it was awesome!! We had two labs: one about chemistry (stuff blew up and we got to see liquid light) and electricty (we learned about it's history and saw electricty before our own eyes). We also watched an Imax film called Roving Mars, which was about two rovers (Spirit and Opportunity) who landed on the surface of Mars. These two rovers confirmed that Mars did have liquid water sometime in it's past, which raises the chance of their being life on it (be it present or past).
