PART $4$: CONCLUSION$|$

While standing in line at a local burger place, an older man finds out that you are an expert in physics. He

tells you that he went to the beach on a recent vacation and saw a huge log floating in the ocean. But when

he threw a pebble into the ocean, it sank. He says that he doesn't understand why and asks if you have any

idea.

Write a five$-$sentence minimum explanation of why the log floated but the pebble sank. You must use the

words mass, volume, and density. $(10$ points total$)$
