1. Ask the students to name a few things that are hot, cold.
2. Take three large mugs. Label them as A, B and C. Put cold water in mug A and hot water in mug B. Mix some cold and hot water in mug C. Now dip your left hand in mug A and the right hand in mug B. After keeping the hands in the two mugs for 2–3 minutes, put both the hands simultaneously in mug C. Do both the hands get the same feeling?
