Inverness Science Festival returns this month – entirely on-line – with a range of activities for people of all ages.

The Festival is organised by the University of the Highlands and Islands science technology engineering and maths (STEM) team.

Running from Thursday 29 April to Saturday 15 May, the event aims to inspire people to learn more about science and to develop a passion for subjects including biology, chemistry, astronomy and physics.

This year's event will include a virtual lab tour, a biology-themed knitting event and an online lecture about the crossover between art and archaeology.

There will also be a range of family resources and try at home activities developed with support from Aberdeen Science Centre and the Royal Zoological Society of Scotland. Children can learn how to build a Lego catapult, make a battery from an orange or create a mini satellite.

A virtual science, technology, engineering and maths fayre will be held on Monday 3 May to celebrate the University of the Highlands and Islands' tenth birthday, with hands-on activities linked to a variety of university courses.

The festival will draw to a close on Saturday 15 May with an online pub quiz where participants will be encouraged to test their knowledge on a range of scientific topics.

Evelyn Gray, the university's STEM Administrator, said: "The Inverness Science Festival team have worked hard to create an exciting virtual programme to inspire people of all ages about science.

"The online format means that people don't have to be in the Inverness to enjoy the events and activities, the festival can now be accessed from anyone across the globe!

"It's fantastic to be part of such a fun event, particularly in the year our university partnership celebrates its tenth birthday. We hope you can join us!"
