Questions+from+Class

Physical Science is such a broad subject. So..... as unanswered questions are raised during class, I will post them here. The first student who correctly answers the question by emailing me (mchughc@nasdschools.org) a response/explanation will be granted extra credit. Don't forget to include your name with your response, and to include a link to your sources. Please provide complete correct responses.
