Lesson Objective To describe how living things are

Lesson Objective: To describe how living things are classified into broad groups according to common observable characteristics and based on similarities and differences Introduction: Classification means to group similar species together. There are millions of different species living on our planet - different types of plants, animals, fungi, and bacteria. In order to learn more about them, it is necessary for scientists to sort them into groups. Related species can be sorted into different groups by comparing their similarities and differences.

Classification Scientists sort living things into groups using a number of areas. For example: birds have feathers, but no other living things do. So if an animal has feathers, it is classified as a bird.

Carl Linnaeus • A Swedish doctor and scientist, Carl Linnaeus, developed the classification system in the 1700 s. Living things are divided into several main groups, such as animals, plants fungi and bacteria. Each group is then able to be split into smaller groups and then these groups can be divided again and so on. • The classification chart looks similar to a tree! • You can classify or sort any species into groups depending on your theme.
