Pulse Science
Mama: "What is your hearts job?"
Miss C: "Loving."
'Growing Grade By Grade' tested wrist pulse with marshmallow and toothpick.

Results were recorded as mixed.
We switched it up a bit by getting our heart rate up, before placing the marshmallow and toothpick (matchstick!) on your neck pulse!
So much fun!
If you can get it to balance, it bounces pretty high!
To add some math, count the pulse for 15 seconds and multiply by 4 to get your heart rate.
