Aren't we all different? Different hair. Different skin. Different faces. Different heights.

But then, aren't we similar: same body shape, heads, two arms and legs, ears and eyes.

Mrs. Bates's science class have been finding out about how similar and different they are.

They have been looking at what colour their eyes are and they have been measuring their height.

With help from their teacher they have drawn block graphs of the results to show how similar or different they are.

Then they will be in a stronger position to decide whether the variations they observe are determined by inherited characteristics or whether they are caused by the environment that they've grown up in.

Let's join the class and see what's going on....
