Valentine's Day is almost upon us, so today, I have a selection of Valentine's Science experiments for you.
Valentine Science Experiments
Make a stethoscope and listen to a friend's 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.
How about making some pretty flowers ?
The Imagination Tree has some lovely spin art cards.
Finally, as always, we have a themed lava lamp.
If you have any other ideas for me, please add them to the comments below, and if you try any of these, let me know how you got on.
We've got even more ideas in this updated Valentine's Day Science post.

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/
