Why do large ships float even though they are very heavy?

Their shape displaces a large amount of water, creating enough upthrust to balance their weight

If two objects have the same mass but one floats and the other sinks, what is different about them?

Their shape or density

What does it mean if an object is denser than water?

It will sink

What happens when the upthrust on an object is greater than its weight?

The object floats

Why is accuracy important in a floating and sinking experiment?

So that the results are reliable and can show true patterns

What is an example of a real-life object that floats due to its shape, even though it is made of a dense material?

A boat

What does it mean if a result does not fit the pattern in an experiment?

There may have been an error in measurement, or an additional factor affected the result

How does changing the shape of an object affect whether it floats or sinks?

A flatter or more spread-out shape may help it float by increasing the upthrust

If an object is floating, what does that tell us about the forces acting on it?

The upthrust is equal to the object's weight

What is the term for how much space an object takes up?

Volume

What is the dependent variable in an experiment on floating and sinking?

Whether the object floats or sinks

What is the force that pushes objects up when they are in water?

Upthrust

What happens to water when you place an object in it?

Some water is displaced

What do we call the variable that stays the same in an experiment to keep it fair?

The control variable

What is the independent variable in an experiment on floating and sinking?

The factor that we change, e.g., the type of material or shape of the object
