For over 140 years the Institution of Engineering & Technology (The IET) has been inspiring, informing and influencing the global engineering community; supporting technology innovation to meet the needs of society. Come to complete the assembly of a Mediaeval siege engine experiment before trying it out to see how well your finished design works.

Institution of Mechanical Engineers works with leading companies, universities, and think tanks to create and share knowledge, fresh thinking and authoritative guidance on all aspects of mechanical engineering. At the park, the IMechE will be hosting a model bridge building competition and demonstrating a manually operated hydraulic robot arm.

Institute of Physics is a leading scientific society; a charitable organisation with a worldwide membership of more than 50,000, working together to advance physics education, research and application. Join them at the event to take part in various hands-on physics experiments including blowing large bubbles, understanding bouncing balls, exploring the way slinkies travel down steps, trying out balloon helicopters, testing ‘exploding’ lolly sticks, as well as investigating pendula, rope waves, and grass whistles.

STEM Ambassadors use their enthusiasm and commitment to encourage young people to enjoy STEM subjects. They open the doors to a world of opportunities and possibilities which come from pursuing STEM subjects and careers. STEM Ambassadors not only inspire young people, they also support teachers in the classroom by explaining current applications of STEM in industry or research.

Dinosaur detective trail: No longer Priory Park, but Jurassic Park! Find the eight hidden dinosaurs and complete the prehistoric quiz.

The Big Bang Theory: One day we'll try to get the real actors, but in the meantime, you'll have to make do with our life-size cardboard cutouts. Featuring Amy (neuroscientist), Bernadette (microbiologist), Howard (aerospace engineer), Leonard (experimental physicist), and of course Sheldon (theoretical physicist).

Mad Lab: Scientists aren't really all mad, but you can put on an Einstein wig, labcoat and safety specs to look a bit crazy if you'd like.

Trans-park communication dishes: We've sourced a couple of parabolic dishes that are used for directional sound recordings, and we're wondering how well we'll be able to communicate between the two across Priory Park. We have no idea if it will work or not, so come along, try it out for yourself, and see what the results are like.
