Summer chemistry in Cornwall - suncreme supplied

Posted by Larissa Paver on May 14, 2015 1:40 pm

On holiday in Cornwall this summer?  Or lucky enough to live here?  Keen to get people engaged with the chemistry around them?   Why not join our team of public engagement volunteers at the Telegraph Museum Porthcurno to help deliver our Royal Society of Chemistry sponsored ‘Sun, Sea and Sand Chemistry’ project in July and August.
 
Sun: Wednesday 29th July.  Sun-safe or sun-sensitive?  We’ll be working with visitors to get hands on with sun creme, sunglasses and our UV window filters, exploring how UV-sensitive beads work.   We'll encourage them to think about why the beads change colour, and apply this to what the sun may do to their skin and our historic objects. We’ll also be using light sensitive paper and chemistry to create sun-art to take home and treasure.
 
Sea: Wednesday 12th August.  A celebration of the chemistry of local seaweeds, in ‘Seaweed Sea Monsters’ visitors will be able to create their own weird and wonderful beasties, using coloured sodium alginate solution dripped into ice-cold calcium chloride solution. For the young at heart, we’ll have vege-gel sensory activities: a tray of seaweed-based ‘sand’ castles and animals to explore, and the chance to prod, colour, and make worms out of vege-gel ‘jellies’.   We’ll also have local seaweeds, and seaweed based food products on hand for visitors to explore and even taste.
 
Sand: Wednesday 29th August.  Quick, slow or strange sand?  We’ll be getting hands- and feet-on outdoors with cornflour ‘quicksand’, exploring the properties of this amazing fluid. Indoors, we’ll be playing with hydrophobic ‘magic sand’, ‘moon sand’ and good old play sand in an investigation into which makes the best sand sculptures, talking and thinking about the different properties. Visitors will also have the chance to make and take away their own sand art.
 
Activities run from 9,30 am to 4 pm, including set-up and clear-up time.  Detailed activity info will be provided in advance, and training will be available on the day.  One night's free accommodation may be available or we will cover transport costs of up to £25 for each day.  Note Porthcurno is not easy to reach by public transport, but we may be able to arrange lifts to and from Penzance railway station.
