What floats and what sinks? Have a go of this quiz to see what you know.

• 1.

### Will a paper clip float or sink?

• A.

Float

• B.

Sink

B. Sink
Explanation
A paper clip will sink because its density is greater than that of water. When an object is denser than the fluid it is placed in, it will sink. The density of a paper clip is higher than that of water, so it will not be able to displace enough water to float. Therefore, it will sink when placed in water.

### Will a wooden block float or sink?

• A.

Float

• B.

Sink

A. Float
Explanation
A wooden block will float because wood is less dense than water. When an object is less dense than the fluid it is placed in, it will displace an amount of fluid equal to its own weight and float. Since wood is less dense than water, it displaces enough water to support its weight and remains afloat.

### Will a lemon float or sink?

• A.

Float

• B.

Sink

A. Float
Explanation
Lemons will float because they have a density lower than water. The density of an object determines whether it will sink or float in a liquid. If the object's density is greater than the liquid, it will sink. However, if the object's density is lower than the liquid, it will float. In the case of a lemon, its density is lower than that of water, causing it to float when placed in water.

### Will a marble float or sink?

• A.

Float

• B.

Sink

B. Sink
Explanation
Marbles are denser than water, so they will sink when placed in water. The buoyant force acting on the marble is not enough to counteract the force of gravity pulling it down, causing it to sink.

### Will a kowhai seed pod float or sink?

• A.

Float

• B.

Sink

A. Float
Explanation
Kowhai seed pods are known to float. This is because they have a hard outer shell that is filled with air, making them less dense than water. When placed in water, the air trapped inside the pod provides buoyancy, causing it to float on the surface.

### Will a kowhai seed float or sink?

• A.

Float

• B.

Sink

B. Sink
Explanation
A kowhai seed is likely to sink in water. This is because kowhai seeds are relatively heavy and dense. Objects that are denser than the liquid they are placed in will sink, while objects that are less dense will float. Since the kowhai seed is denser than water, it will sink when placed in it.

### Will a crayon float or sink?

• A.

Float

• B.

Sink

B. Sink
Explanation
A crayon will sink in water because it is denser than water. When an object is denser than the liquid it is placed in, it will sink. Crayons are made of wax and other materials that have a higher density than water, causing them to sink when placed in water.

### Will a rubber band float or sink?

• A.

Float

• B.

Sink

B. Sink
Explanation
A rubber band will sink in water because it is denser than water. When an object is denser than the liquid it is placed in, it will sink. The rubber band is made of a material that is heavier than water, causing it to sink rather than float.

### Will a rock float or sink?

• A.

Float

• B.

Sink

B. Sink
Explanation
A rock will sink because it is denser than water. Density is the mass of an object divided by its volume. If an object is denser than the liquid it is placed in, it will sink. Since rocks are generally made of materials that are denser than water, they will sink when placed in water.

### Will a peeled lemon float or sink?

• A.

Float

• B.

Sink

B. Sink
Explanation
A peeled lemon will sink when placed in water. This is because the density of the lemon is greater than the density of water. When an object is denser than the liquid it is placed in, it will sink. In the case of a peeled lemon, removing the peel does not significantly change its density, so it will still sink.
