Any ways to sink a can or jar in a bucket of water so that only half of it is submerged? 10th grade science homework help

Answer 1

This is basic stuff that you already know. You may not know the terms for it, but you already know it.

Anything that floats in water does so because it displaces (pushes aside) water, until it's weight can be born by the water. Aircraft Carriers are made of steel, the carry jet planes and thousands of people, plus tons of fuel, food, equipment, supplies, etc. etc. etc. and they still float.

They are big enough to push away enough water until the water underneath the ship can successfully bear the weight of the ship. Same for container ships, ferries, etc.

A can or a jar can prove the same property.

You can change the shape of the can or jar.

A thinner can (skinnier) or jar will displace less water causing it to sink further.

(A wide shallow pan will displace a lot of water and appear to almost not sink at all.)

You can increase the weight of the can or jar causing the same area to weigh more.

You can do some of both, or all of one or the other.

You can even change what you fill the can or jar with, and that too will change how much it weighs.

Try filling the can with several different things, one at a time, and notice that spent uranium encased in lead, causes the jar or can to sink further than an equal amount of hydrogen gas does.

Surface area and weight of the floating object combine to form a balance which is affected by many factors. An object like an aircraft carrier or a cargo ship will float higher in the sea than it will on a river.

Because the density of the ocean water is heavier or thicker than that of fresh water.

Think these things through.

It's time to start believing in your own knowledge.

Answer 2

ok how about putting in something light but not 2 lite....maybe 10 eggs or something

Answer 3

Fill the jar half way full of water, and put the lid back on. It'll float half way up now.

Answer 4

I'm in 8th but I'll give it a try.  How about putting an object that has a low mass to weight ratio and high buoyancy.  Try styrofoam or maybe stuff the thing with grapes!  Close the lid and it should float.
