I sea I care!

This term our integrated unit is called “I sea I care” and it’s about marine life. We watched two videos about the Great Barrier reef and life in the deep ocean. Here are some questions we came up with after watching the videos:

How many sea creatures are in the ocean?
How many sharks are in the ocean?
Why do people catch creatures?
How can spiders live under water?

What would be different if people didn’t fish?
What would change if there were no fish in the ocean?
Why and how do some sea creatures glow in the dark?
If people can go to the moon, why can’t people go to the very bottom of the ocean?
Is it possible for people to make gear to go to the very bottom of the deep ocean
What would change if everyone knew everything about the ocean?
Why do whales only eat plankton? Shouldn’t they eat more than that?

What would happen if we didn’t have coral reefs? As a class, we explored this question and came up with these answers:
Fish wouldn’t have a place to hide or live so sharks/predators could easily get them.
The food chain would be affected. For example bigger fish eat the small fish. So if the small fish were no longer there, the bigger fish would die.

Can you answer any of these questions? Or can you think of another question?
