Experiment
DRINK UP (DOWN)!
If you drink water upside down, will it run out through your nose or ears?
Curriculum objectives - Science:
- conversation about what energy is, and explore different energy chains
- describe how muscles and bones work, and link this to movement
You need:
- A glass of water.
- A straw with a kink.
This is what you do:
Here it is best to be two helping each other!
Place the straw in the water glass.
Stand with your head against the wall.
Get someone else to help you set the glass so you can suck through the straw.
What is going on?
You might think that the water would follow gravity and flow down (and out through the ears?), but the muscles in the esophagus in the throat are so strong that they squeeze the water up into the stomach.
