Ways to use these human body questions
Use these as a health-class or science warm-up: read a question, then have everyone point to the body part before anyone says the answer, which gets kids moving and checking their own elbows, wrists and collarbones. The easy ones about pulse, pores and the funny bone suit a younger crowd, while words like epiglottis and cochlea give older students and grown-ups something to chew on. They also work at a sleepover or on a long car ride, where a quick round of 'which grows faster?' and 'find your own pulse' turns the human body into a game everyone can test on the spot.
