Science, treasure hunts, shire horses, pram walks, bird walks and more for an illuminating weekend

1 Six scientists will be busy doing their scienctific thing around the streets of Norwich tomorrow, waiting to be discovered. Families can follow the free Science Treasure Hunt to find the scientists, see the science, learn about how how science shapes our lives and enjoy exciting hands-on experiments and activities.

The six science stands will focus on: the science of tea, the science of sound, amazing animals, electric bacteria, the chemistry behind smell, and solar science. The treasure hunt has been created by members of British Science Association Norwich as part of British Science Week. To join the fun simply pick up a free map and clues at the Forum, and if you collect all six stamps there is a prize draw too. The treasure hunt runs from 10am to 5pm and should take around two hours to complete, including enjoying the science activities at each stop.

2 Have a go at geocaching. At Dunwich Heath there are three geocaching trails to choose from and each geocache has fascinating information about the place where it is hidden. The National Trust can loan a GPS unit and explain how to get started. This weekend the Dunwich Heath shop and tearooms are open 10am to 4pm and the heath is open from dawn to dusk.
