Physical Science Properties of objects and materials Objects have many observable properties, including size, weight, shape, color, and the ability to react with other substances. Objects can be described by the properties of the materials from which they are made, and those properties can be used to separate or sort a group of objects or materials. The characteristics of organisms Organisms have basic needs. Each plant or animal has different structures that serve different functions. Organisms and their environments An organism's patterns of behavior are related to the nature of that organism's environment, including the kinds and numbers of other organisms present, the availability of food and resources, and the physical characteristics of the environment.
All organisms can cause change in the environment in which they live.
Some of these changes are beneficial. Others are detrimental. Earth and Space Science Properties of earth materials Earth materials are solid rocks and soils, water, and the gases of the atmosphere. The varied materials have different physical and chemical properties which make them useful in different ways, for example, as resources for growing plants. Soils have properties of color and texture, capacity to retain water, and ability to support growth of plants.
