The free event, on Saturday 23 September also features marine touch tanks and robots of all shapes and sizes - including Pepper the humanoid helper.
A mixture of fun-packed events will take place on campus in the Lyell Centre and University library.
Budding scientists will be able to explore science secrets of the world and get their hands on an augmented reality sandbox, which creates virtual floods and earthquakes.
There’s also plenty of fun information on our deep oceans and the strange creatures who live 1000s of meters under the sea.
This is a fun-packed day for all the family, revealing top science secrets that the public don’t normally get to hear about.
The British Geological Society, will host tours of their marine operations workshop where equipment used to survey the seas will be on display.
Visitors can also find out more about geomagnetism, thermal rock imaging, maps, apps, gold panning, seismology and volcanology. There’s also a special visit from Barnie the Dino.
Elsewhere on campus, the Museum and Archive will be joined by the Institution of Civil Engineers (ICE) Scotland on the ground floor of the university library.
On display will be 'Building for the Future' exhibition, featuring Thomas Telford’s Dean Bridge and the work of New Town based civil engineers, Carfrae Morrison CE.
A building heritage trail quiz for children and families will also take place in the Museum, the ICE Scotland Museum in the William Arrol Building and the Lyell Centre.
Laura Wicks, Public Engagement Co-ordinator added:
“Our museum also has a wealth of information behind closed doors, and we’d urge everyone to come and visit us for this free day out.”
The events at the Lyell Centre are on between 10am and 5pm while the events at the museum are on between 11am and 4pm.
Volunteers will also be on hand to offer guided tours of the ICE Scotland museum. People can sign up here for these tours.
