LS.5.1 Understand how structures and systems of the human body perform functions necessary for life.
LS.5.1.1 Use models to recognize the organizational structure of humans as a multicellular organism (cell, tissue, organ, system, organism).
LS.5.1.2 Use models to compare the major systems of the human body (digestive, respiratory, circulatory, muscular, skeletal, nervous) as it relates to their functions necessary for life.
Organisms, or any living thing, can be classified as unicellular (surviving with only one cell) or multicellular (needing multiple cells to stay alive).
Unicellular organisms, like bacteria, can only be seen with a microscope while multicellular organisms can be as small as a tick (but still visible to the naked eye). Multicellular organisms are more complex in structure and include plants, animals, and fungi.
PS.5.2.1 Carry out investigations to explain how factors such as gravity, friction, and change in mass affect the motion of objects.
PS.5.2.2 Use mathematics and computational thinking to infer the motion of an object (including position, direction, and speed).
"Anytime there is a change in motion, force is the responsible party. It has to overcome inertia to act on an object. Inertia keeps an object either sitting still or moving at a constant speed. " - Scholastic Inc.
