There may be some specific knowledge or skills you want teach, that's great! But also think about the core behaviours and processes that you would like the learners to develop during the course of your experience. These are often referred to as a growth mindset.
It can help to think about three aspects of learning. Skills to develop, knowledge to take away and perhaps most importantly, learning behaviours and characteristics.
Here are some examples:
To be able to throw and shape a pot on a wheel.
To be able to groom and tack up a nervous horse.
To be able to control and time a serve.
To know the difference between the queen, the worker and the drone honey bees.
To know a range of opening moves in chess.
To know the creation of the world according to Norse mythology.
Develop focus and concentration.
Practice seeking helpful feedback.
Work persistently through challenges.
