Pronounced petals

I'm midway through a spare time (what spare time!) Preparing to Teach in the Lifelong Learning Sector course, acronym PTLLS but pronounced petals. It quickly became apparent to me that my stock approach to talks by Powerpoint with pretty pictures wouldn't cut the mustard if I was going to succeed at this particular challenge. Formal post 16 teaching needs to incorporate so much these days from inclusion, equality and diversity to Health and Safety, numeracy, literacy and ICT, with a touch of healthy living and Education for Sustainable Development and Global Citizenship sprinkled on the top for good measure. 

There's only a couple of sessions left, one of which is a 30 minute Micro Teaching session that will be, gulp, filmed!! We've been advised to pick a subject to talk about that we are interested in. Whilst some former attendees as an example have delivered a session around the History of the Musket or the finer points of Yoga I'm toying with the lofty concepts of Citizen Science or Nature Deficit Disorder. Am I being too ambitious?
