Peter Liu-Brown reflects on various activities from rock climbing to camping during a school trip. For rock climbing, he was initially frightened but overcame his fear of heights by completing the climb with encouragement. During a bike ride, he was impressed by others' determination after falling yet continuing. At a school, Peter felt sorry for students without shoes and was happy they seemed satisfied with little. He reflects on teamwork lessons from building catapults and how communication helped in constructing a stable tent during camping. Caving was an enjoyable challenge where teamwork allowed them to find clues and win a prize.
