Scuba diving is certainly a one of a kind experience. Have you ever thought, how do scuba divers or submarines take such deep dips in the water?
Here’s an easy experiment to help kids understand the science behind this.
What you need:
– A sheet of paper
– Sketch pens
– 2 paper clips
– Straw
– A bottle of water
Steps:
1. Draw a scuba diver on a sheet of paper and fill in some colors. Cut out the diver.
2. Bend a straw and attach it to the back of the scuba diver cut out, extending to the bottom area of the cut out.
Place the diver cut out in a bottle of water and ask the kids to squeeze the bottle and then release it, observing close, what happens!
When the bottle is slightly squeezed, the cut out moves downwards. As the pressure is released, it moves upwards!
What is happening here is that, the straw that’s stuck behind the scuba diver fills up with water when the bottle is squeezed.
The actual scuba divers go down by inflating and deflating their buoyancy control device!
