The events, in Brighton, Eastbourne and Newhaven, are being run by University Technical College (UTC), a college offering academic and technical education for 14 to 18 year olds.
The college, being built at Railway Quay, Newhaven, currently is receiving applications and will welcome its first students next September.
UTC, also sponsored by the educational charity the Aldridge Foundation, Lewes District Council, and Veolia Environmental Services plc, will focus on science, engineering, technology, maths and computing, specialist skills which are in demand by the growing marine engineering and environmental technology sectors.
