School visit: scale of the Universe
I went on a school visit this week to Springfield Technology College - a secondary school with a focus on science/technology just to the north of Portsmouth. Kudos to the teachers at the school for suggesting I speak with two groups one after another - thus giving me maximum outreach impact for my travel. The first group I spoke with was 60 YR7 pupils (11 and 12 yr olds). I chose to talk to them about "The Scale of the Universe" as it allows me to talk about planets and use my fun solar system model, but also link to cosmology and the types of science we focus on here in Portsmouth ICG. I started with the inflatable solar system model. As previously used at out BBC StargazingLIVE Event at the Spinnaker Tower, and already on their 3rd school visit. Inflatable planets decorate the Spinnaker Tower (in an approximation of the actual layout of the Solar System in Jan 2012). To introduce this to children I start with the Earth. I ask them to think about distances they are familiar...
