Hooked on Science: The beating heart
Using a few items from around the house you can observe your pulse.
STEP 1: Using the scissors, cut the straw in half.
STEP 2: Place the straw into the clay.
STEP 3: Flatten the bottom of the clay.
STEP 4: With your palm up, rest your hand on a flat surface.
STEP 5: Place the bottom of the clay on your wrist.
You can observe your pulse by watching the straw move back and forth. This happens each time your heart pumps blood throughout your body. You can discover how many times your heart beats in a minute by counting the complete back and forth movements the straw makes in one minute.
