Third Grade Standards For:

Energy and matter have multiple forms and can be changed from one form to another. As a basis for understanding this concept:

Students know energy comes from the Sun to Earth in the form of light.
Students know sources of stored energy take many forms, such as food, fuel, and batteries.

Energy and matter have multiple forms and can be changed from one form to another. As a basis for understanding this concept:

Students know sources of stored energy take many forms, such as food, fuel, and batteries.
Students know machines and living things convert stored energy to motion and heat.
Students know energy can be carried from one place to another by waves, such as water waves and sound waves, by electric current, and by moving objects.
Students know matter has three forms: solid, liquid, and gas.
Students know evaporation and melting are changes that occur when the objects are heated.
Students know that when two or more substances are combined, a new substance may be formed with properties that are different from those of the original materials.
Students know all matter is made of small particles called atoms, too small to see with the naked eye.
Students know people once thought that earth, wind, fire, and water were the basic elements that made up all matter. Science experiments show that there are more than 100 different types of atoms, which are presented on the periodic table of the elements.

Adaptations in physical structure or behavior may improve an organism's chance for survival. As a basis for understanding this concept:

Students know plants and animals have structures that serve different functions in growth, survival, and reproduction.
Students know examples of diverse life forms in different environments, such as oceans, deserts, tundra, forests, grasslands, and wetlands.
Students know living things cause changes in the environment in which they live: some of these changes are detrimental to the organism or other organisms, and some are beneficial.
Students know when the environment changes, some plants and animals survive and reproduce; others die or move to new locations.
