There was a record turnout for the Edinburgh International Science Festival family open day at Oriam, last weekend.
More than 5,200 people attended events hosted by the university - in support of the much-loved science event.
This year, the institution partnered up with the British Geological Survey, Scottish Seabird Centre, Strathclyde and Napier University to bring science to life for all age groups.
And university organisers worked with Ratho Coaches to bring the local community of Wester Hailles to the event, which included activities such as a robotic surgery, glow stick workshops, underwater robots and earthquakes.
Linked to Heriot-Watt University's Year of the Sea campaign, participants joined marine scientists and got up and personal with some a variety of sea creatures from around Scotland's shores.
Gareth Pender, Deputy Principal Research and Innovation, said: “Well-done to all the team for an incredibly successful event. Opening up science to our local communities and all age-groups is particularly important and one of our key strengths.”
Simon Gage, Director, Edinburgh Science Festival, added: “Congratulations to everyone involved in staging such a hugely popular day of science. It was very pleasing indeed to see so many enjoying the very varied content on the campus. Well done!”
