AUS-e-NEWS

AUS-e-NEWS is AUS-e-TUTE's own free quarterly newsletter for chemistry teachers and students.

Each edition of AUS-e-NEWS contains:

• A feature article (placing the chemistry students learn in an interesting, relevant context)
• Suggestions for further reading (links to AUS-e-TUTE tutorials relevant to the article)
• Suggestions for practical investigations that students could design and conduct
• Questions for students to answer based on the chemistry in the article
• A student tip (based on common student misconceptions or mistakes when answering questions based on the chemistry in the article)
• A chemistry joke (related to the chemistry in the article ofcourse)
• A puzzle (based on the chemistry in the article)

AUS-e-NEWS is emailed out in:

• March
• June
• September
• December
