Not too difficult if you keep it simple and are dealing with people who have some outdoors experience.
I teach survival in Australia for Aeromedical Evacution Teams using four simple rules:
PROTECTION - includes:First Aid, Clothing, Shelter and Fire.
LOCATION- Improvised signals and Safety Equipment Aids.
WATER- Preserving(water loss, symptoms etc)and Obtaining water.
FOOD. Last and least important as the others in order.
Includes Procurement, rules for toxic plants and edibility test, Common native food(animal and vegetable), Traps and snares, Cooking and Food Preservation.
A big call to do it in an hour but you can use handouts to cover your information in more detail.
The above is only a rough outline, but feel free to pick it all to bits.
I don't mind friendly debate.
