| Chemical Reaction | A process in which atoms rearrange to form new substances |
| Organisms | Living things, such as plants, animals, and bacteria |
| Metabolism | The body's use of molecules for energy and growth |
| Phase | A noticeably different form or state of the same substance |
| Model | An object, diagram, or computer program that helps us understand somthing by making it simpler or easier to see |
| Scale | The relative size of things |
| Glucose | A molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms |

| Refute | To provide evidence that goes against a claim |
| Substance | Something that is made up of all the same atoms or groups of atoms |
| Extended Structure | A structure formed by repeating groups of atoms linked together in a large network |
| Molecule | A group of atoms joined together in a particular way |
| Kinetic Energy | The energy that an object has because it is moving |
| Product | An ending substance that is made during a chemical reaction |
| Property | Something that can be observed about a substance, such as color, smell, or boiling point |

| Claim | A proposed answer to a question about the natural world |
| Evidence | Information about the natural world that is used to support or go against a claim |
| Scientific Argument | A claim supported by evidence |
| Prokaryotic | Smallest, simplest cells that make up single cell organism and lack a nucleus |
| Eukaryotic | Cells containing specialized internal organelles |
| Nucleus | The control center of the cell, holds the DNA |
| Mitochondria | Bean shaped organelle that releases energy from glucose molecules for the cell to use |
| Cell Membrane | Barrier around the cell that controls what goes in and out of the cell |
| Vacuole | Large storage organelle found in plants, stores water, food, and sometimes waste |
| Chloroplast | Organelles in plant cells that store chlorophyll where light energy is turned into glucose during photosynthesis |
| Organelle | Membrane bound structures within the cell that have specific jobs |
| Cell Division | When a parent duplicates it contents and then divides into 2 new cells |
| DNA ( deoxyribonucleic acid) | Genetic information that is located in to nucleus, and is passed from parent to offspring |
| Ribosomes | Organelle that makes protein for the cell |
| Cytoplasm | Gel like substance that fills the cell |
| Oxygen | A molecule that organisms get from the air or water around them and use to release energy |
| Amino Acids | Molecules that are the buliding blocks of proteins |
| System | A set of interacting parts forming a complex whole |
| Digestive System | The body system that takes in food and breaks it down |
| Respiratory System | The body system that takes in oxygen and releases carbon dioxide |
| Circulatory System | The body system that transports molecules to and from all cells of the body |
| Energy | The ability to make things move or change |
| Protein | A category of large molecules that perform inportant functions inside living things |
| Starch | A type of energy storage molecule made of many glucose molecules connected together |
| Tissue | A group of cells that work together to perform a specific job |
| Heart | Muscular organ that pumps blood throughout the body |
| Arteries | Blood vessels that carry oxygen rich blood from the heart to the body |
| Veins | Blood vessels that return oxygen poor blood back to the heart |
| Capillaries | Tiny blood vessels where the exchange of oxygen, carbon dioxide, nutrients and waste occurs between the blood and the cells |
| Circulation | Movement of blood through the heart and blood vessels, delivering oxygen & nutrients to the body, and removing waste products |
| Lungs | Main organ of the respiratory system where gas exchange occurs |
| Diaphragm | Muscular structure that separates the chest cavity from the abdominal cavity and plays a key role in breathing |
| Alveoli | Tiny air sacs in the lungs where the exchange of oxygen and corbon dioxide take place |
| Ingestion | Process of taking food into the body |
| Digestion | Process of breaking food down into it's smallest parts |
| Respiration | Process by which oxygen is taken in and carbon dioxide is released by an organism |
| Excretion | To remove waste |
| Homeostasis | The body ability to maintain a stable environment, even when external conditions change |
| Voluntary | You need to decide on the action (think it) before it happens, done by choice |
| Involuntary | Happens without you thinking about doing it, occurs automatically |
| Smooth Muscle | Type of muscle found in internal organs that operates involuntarily (you dont have to think about it, it just happens). Example the muscle that makes up the esophagus |
| Cardiac Muscle | Type of muscle tissue that makes up the heart and operates involuntarily (you dont have to think about it for it to happen) |
