Chris Hadfield is coming to our classroom!

Ok, so not in person. But on Oct 16th, we will take part in a virtual lesson with him over cyberspace. We have the chance to submit questions to him to answer during the lesson. Questions might be about his time on the International Space Station, or his preparation for becoming an astronaut. If you have something you want to ask, please submit your questions to me via the blog. Remember to include your name in the post.
