I am in the process of preparing an Ignite presentation on climate change, expressing the basic point that the amount of climate change we experience will depend primarily on what proportion of the world’s fossil fuels we burn.
The Ignite format is an odd and challenging one. Each person speaks for five minutes. At the same time, each has a set of 20 slides which automatically advance every 15 seconds. These factors make it challenging to express yourself clearly and effectively.
The earliest drafts of my presentation suffered from my natural tendency towards digression. I am moving forward now more confidently, having timed myself reading four examples of text for five minutes each. Two were written by me, two were speeches written by others.
I found that I read text similar to that in my presentation at a rate just over 180 words per minute. That translates to about 45 words per slide. To compensate for any issues with shuffling notes or distractions, I will write 40 words of pre-prepared comments to accompany each slide, reducing the risk that the unusual Ignite format will leave me unable to express my point fully.
