Discover the physics of buoyancy, water displacement, and how heavy metal objects can float in this exciting underwater adventure. Join Emma, Dr. Owl, and Ziggy the Robot as they explore the secrets…
Welcome back, Emma.
We missed you in the lab over the break.
Did you have a good summer trip?
I had the best trip ever, Dr. Owl.
That sounds absolutely fascinating, Emma.
Did you get to look through the periscope?
I did, and it was super cool! But the submarine was just parked on the water, and it didn't sink or float around.
It made me wonder, how does a giant metal ship actually dive down deep into the ocean and come back up?
Beep boop.
Did someone say submarine? Because I, Ziggy, have invented the ultimate underwater exploration vessel.
It is called the bathtub-o-matic.
Just ignore the fact that it sank straight to the bottom of the kiddie pool.
Oh, Ziggy, I don't think bathtubs are supposed to sink like that.
Indeed, they are not.
But Ziggy's little mishap brings us right to the heart of today's mystery.
How does a heavy metal submarine control when it sinks and when it floats? Explorers, get ready to dive deep into the science of submarines.
