Question

what is an easy way to encourage students to stay hydrated?
let them know hydration improves performance.
encourage them to drink water between each class.
tell them to drink 8 glasses of water per day.
have them track their hydration with a \water diary.\

Explanation:

Encouraging students to drink water between each class is a practical and easy - to - implement method. It fits into their daily school routine without adding excessive complexity. Telling them to drink 8 glasses a day might be too abstract or difficult to follow in a school setting. Letting them know hydration improves performance is more of an informational point rather than an easy - to - execute action. Having a “water diary” could be seen as an extra task.

Answer:

Encourage them to drink water between each class.
