We think everyone can learn about invasive non-native (Alien) species so we’ve put together an educational resource – ‘Alien Detectives’. It is full of exciting, challenging and fun activities for the young - and not so young!
You'll find presentations, activities, worksheets, quizzes, crafts, puzzles and games, all themed around invasive alien species and the river environment which can all be downloaded and shared. There is an introductory presentation to start you off and all activities have notes and answer sheets to help you along – so you don’t need any prior knowledge to use and enjoy them. The activities can be done in groups e.g. a school class but many can be completed individually at home or in the outdoors
When you’ve learned about invasive non-native species your teacher, group leader, mum, dad or carer can award you ‘Alien Detective’ status and you can download your hard earned Alien Detectives certificate. Or you could award it to yourself!
The activities are mostly, but not all, aimed at primary school students, but we think anyone with an interest in invasive species will enjoy and learn from them too! Several of these activities could also be used if you are working towards your John Muir Award, to help you explore and conserve your wild space.
The Alien Detectives resource is presented over seven sections, most is on this page, but there are a couple of other places to visit too:
- The Alien Detectives activities (Sections 1-5, below)
- River and Outdoor activities (Section 6)
- Activities, games and puzzles (Section 7)
- Additional Information (Links for background material and images, curriculum links and links for people how may be able to help you deliver some of the activities in a group or school setting).
You are welcome to copy and share these resources for personal and educational use. All content is ©Scottish Invasive Species Initiative.

Section 2 : Alien Landings
In this session you'll think about how the aliens have travelled and landed!
2.1 Around the world
Where did they come from? This worksheet activity looks at where all these species travelled from around the world. (Indoor)
2.2 Alien landings
How and why did they get here?
This is a active game to learn about the methods of non-native species introductions, but could easily be adapted to do as an individual quiz. (Group, hall or outdoor)

2.5 Plant collecting
A worksheet activity about plant collecting that follows on from the boardgame.
2.6 Make a Wardian case
The Wardian case (a terrarium) revolutionised plant collecting. A practical activity to discover if and how the Wardain case worked.
Session 3 : The Alien Invasion
What makes a successful alien? These activities will help you explore what makes something "invasive", what are typical invasive characteristics and traits.
3.1 What makes a good invader
Watch the powerpoint presentation and let us explain what are the typical invasive traits that an alien may have. (Indoor)
