Saturday 20 and Sunday 21 July 2019


10am – 5pm


Based around The Hive, Princess of Wales Conservatory and Jodrell Laboratory.


Included with entry to the Gardens

Grab your goggles, slip on a lab coat and get stuck in to the Kew Science Festival.  

Join us for a weekend of wild workshops, hands-on experiments, shows and behind the scenes tours, that will captivate children and adults alike.

Meet Kew’s scientists and find out what they’re doing to protect rare and threatened plants and fungi.

Unleash your inner scientist as you carry out your very own experiments. Size up a tree, peer down a microscope, hold the world’s largest seed and taste the smallest. Chat to a giant, glowing fungus, and experience the best tasting chemistry lesson ever.

With a broad and varied programme designed to appeal to all ages, there’s something for everybody. Come curious, leave inspired.

Important information

Most of the activities are drop-in. However, some activities need to be booked when you arrive at the Science Festival.

Bookable activities are very popular and are available on a first come, first served basis. We recommend arriving and booking early, to avoid disappointment.

Parents, guardians and carers must ensure that children and vulnerable adults are accompanied and adequately supervised at all times.


Photography and filming may be taking place at the Science Festival for promotional purposes.

If you would prefer not to be caught on camera, please do alert the photographer/filmmaker clearly on the day.
