Final answer:
Andrea taught the kids relaxation techniques such as sitting comfortably with a relaxed body posture, being in a quiet environment with eyes closed, repeating calming mantras, and focusing the mind on pleasant thoughts.
Step-by-step explanation:
The ways Andrea taught the kids to relax in public involve several relaxation techniques. Firstly, she encouraged the children to sit upright on a comfortable chair with feet on the ground and body in a relaxed position. This posture helps in reducing tension and promoting a sense of groundedness. Secondly, being in a quiet environment with eyes closed allows the kids to focus inward and calm their senses. Thirdly, Andrea taught them to use mantras by repeating a word or a phrase, such as 'alert mind, calm body,' which can guide the mind to a peaceful state. Lastly, she showed them how to engage in passive relaxation by allowing the mind to focus on pleasant thoughts, such as the beauty of nature or the comforting sensation of warmth circulating in the body.
