Do you know the difference between a sphere and a circle? Here are five stunning spheres facts for kids.

Spheres Facts for Kids Fact Number 1: Spheres have Perfect Symmetry

A sphere is a three-dimensional shape. A sphere is perfectly symmetrical, meaning if you were to fold it in half both sides would match up exactly. Because a sphere is perfectly symmetrical, it doesn’t matter what way you fold the sphere, both sides will match up exactly.

Spheres Facts for Kids Fact Number 2: Diameter and Radius are Used to Measure The Length of a Sphere

The distance from the centre of a sphere to its surface is called the radius. The diameter of a sphere is the maximum distance through the sphere. The diameter is twice the size of the radius, meaning that two radii are equal to the diameter. You can work out the volume and surface area of a sphere using the number Pi (π), which is the same for every sphere.

Spheres Facts for Kids Fact Number 3: A sphere has only One Surface

Did you know, because a sphere is completely round it has no corners or no edges. This makes the sphere the only shape to have no flat surfaces. The Earth is often mistaken for a sphere shape and although the Earth looks like an exact sphere it is called a spheroid. This is because the Earth’s North and South poles are slightly flat, meaning it is not a perfect sphere.

Spheres Facts for Kids Fact Number 4: You See Spheres in your Everyday Life

There are many real-life objects in the shape of a sphere. You can see spheres in the food you eat, such as oranges, cherries and melons. You see spheres in your house such as light bulbs, Christmas decorations and marbles. You also see spheres when you are outside, such as footballs, stones and golf balls. Look around your house and see what sphere shaped objects you can find!

Spheres Facts for Kids Fact Number 5: Half a Sphere is Known as a Hemisphere

A hemisphere is exactly half a sphere. Any sphere can be divided into two equal parts called hemispheres. They are divided by a two dimensional surface that goes through the centre of the sphere. Although the Earth isn’t a perfect sphere, it uses hemispheres to divide it into four separate sections. There is the Northern Hemisphere, Southern Hemisphere, Western Hemisphere and Eastern Hemisphere. The Equator is similar to a sphere’s diameter, it separates the Northern Hemisphere from the Southern Hemisphere.
