Class - Fourth Grade Science

Definition: In science, a class is a group of objects or organisms that have similar characteristics. These shared characteristics can be used to classify and organize the objects or organisms into groups.

Types of Classes:

1. Living Things: This class includes all living organisms such as plants, animals, and humans. Living things can further be classified into different groups based on their characteristics, such as vertebrates and invertebrates, or flowering plants and non-flowering plants.
2. Non-living Things: This class includes objects and materials that do not possess life, such as rocks, water, and air. Non-living things can be classified based on their properties, such as solid, liquid, or gas.
3. Matter: Matter is another class that includes both living and non-living things. Matter can be categorized into solids, liquids, and gases based on their physical properties.
