Deep-Ocean Exploration Technology
Your child can explain why more of the Moon is mapped than the sea floor. The deep sea is dark, freezing, and crushing, which makes it very hard to reach.
In curriculum terms
Explain how crewed submersibles (Alvin, Deepsea Challenger) and remotely operated vehicles (ROVs) allow exploration of the deep; describe acoustic seafloor mapping using sonar and why only ~25% of the ocean floor has been mapped at high resolution; explore why the deep ocean is harder to explore than the surface of the Moon (pressure, cold, darkness, communication difficulties); survey astrobiology missions targeting ocean worlds in our solar system

Try this together
Can your child explain why more of the Moon's surface has been mapped in detail than Earth's ocean floor — what makes deep ocean exploration so much harder than looking at the Moon?
