    Make a Stethoscope and listen to a friends heart beating.

    Find out what happens to your pulse rate after exercise and how fast it returns to normal.

    Explore respiration by making a pizza.

    How about learning about melting, by making these melt and pour soaps from Red Ted Art.

    Red Ted Art also has a fantastic post about making  candle wicks.

      What a fun list. We of course love the lava lamps for Valentines Day. I’m going to try the homemade stethoscope. Here’s another heart science project to add to your list – http://www.stevespangler.com/science-experiments/mix-a-little-science-into-your-valentine%E2%80%99s-day/
