II.I.II: Know that energy is needed to get things done and that energy has different forms.
II.I.II.1: Identify the characteristics of several different forms of energy and describe how energy can be converted from one form to another (e.g., light to heat, motion to heat, electricity to heat, light, or motion).
II.I.III: Identify forces and describe the motion of objects.
II.I.III.1: Know that energy can be carried from one place to another by waves (e.g., water waves, sound waves), by electric currents, and by moving objects.
II.I.III.2: Describe the motion of an object by measuring its change of position over a period of time.
II.I.III.3: Describe that gravity exerts more force on objects with greater mass (e.g., it takes more force to hold up a heavy object than a lighter one).
II.I.III.4: Describe how some forces act on contact and other forces act at a distance (e.g., a person pushing a rock versus gravity acting on a rock).
II.II.I: Know that living things have diverse forms, structures, functions, and habitats.
II.II.I.1: Explain that different living organisms have distinctive structures and body systems that serve specific functions (e.g., walking, flying, swimming).
II.II.I.4: Describe the components of and relationships among organisms in a food chain (e.g., plants are the primary source of energy for living systems).
II.II.III: Know the parts of the human body and their functions.
II.II.III.1: Know that the human body has many parts that interact to function as systems (e.g., skeletal, muscular) and describe the parts and their specific functions in selected systems (e.g., the nose, lungs, and diaphragm in the respiratory system).
II.II.III.2: Recognize that the human body is organized from cells, to tissues, to organs, to systems, to the organism.
