  • A group of interacting parts that work together to perform a function.
    System
  • The interior of any cell. There are many structures and functions that happen here that are too small to see even with a microscope.
    Cytoplasm
  • The process of water turning from a gas into a liquid
    Condensation
  • Part of some plant cells that allow the cell to make the food they need to live using energy from the Sun.
    Chloroplast
  • The natural and manmade places where water is found
    Reservoir
  • A push or a pull on an object, or from one object to another.
    Force
  • The process of creating new molecules by breaking apart the molecules in the starting substances, which creates one or more new substances.
    Chemical Reaction
  • Two or more atoms held together by a bond.
    Molecule
  • The process that causes a liquid to turn into a gas.
    Evaporation
  • Criteria: The “like-to-have” parts of a solution to a problem. These parts let us compare solutions and decide if one solution is better than another.
    Criteria
  • The “must-have” parts of a solution to a problem. These parts must be done in order to have a possible solution.
    Constraints
  • Part of the cell that stores and protects the parts of the cell (genes) that control the cell's growth, reproduction and function.
    Nucleus
  • Water draining down into the ground/soil
    Infiltration
  • The starting substances that are mixed together to start a chemical reaction.
    Reactants
  • The layer that controls what enters and leaves the cells, the boundary of the cell.
    Cell membrane
  • An area of higher elevated land that naturally determines where surface water and groundwater drain.
    Watershed
  • When molecules move at a medium speed and slide past each other.
    Liquid
  • The ending substances that are created during a chemical reaction.
    Products
  • The smallest particle of matter that has unique properties. The basic building blocks of all matter.
    Atom
  • A system composed of tissues that work together to perform a specific function
    Organ
  • The ability to dissolve, or become integrated into a liquid, such as water.
    Solubility
  • Variable/condition that is purposely changed in the investigation. Mnemonic device: “What I CHANGE in the investigation.” (Independent starts with “I”)
    Independent Variable
  • A system composed of cells that work together to perform a specific function.
    Tissue
  • The material, process or condition that is purposely kept the same in the investigation.
    Control
  • The number one way to know if something is living.
    It's made of cells.
  • The force that pulls things toward the Earth
    Gravity
  • The process that causes a liquid in plants to be released as a gas.
    Transpiration
  • When molecules move slowly/vibrate and are tightly packed.
    Solid
  • The measured results of the investigation. "This is the variable that DEPENDS on what I changed.”
    Dependent Variable
  • Part of the cell that converts food into a form of energy that the cell can use to grow, reproduce or do its function.
    Mitochondria
  • When molecules move fast, far apart and do not touch unless they collide.
    Gas
