3D: Short for three-dimensional. This term is an adjective that describes something that has characteristics that can be described in three dimensions: height, width, and length.
Arthropods: A type of invertebrate animal in the phylum Arthropoda, which includes insects, crustaceans, arachnids, and myriapods, characterized by an exoskeleton made of a hard substance called chitin and by body segments with paired articulated appendages.
Ash: (in geology) Small, light pieces of rock or glass ejected by a volcanic eruption.
biology: The study of living organisms. Scientists who study living organisms are called Biologists.
Crustacean: Hard-shelled aquatic animals such as lobsters, crabs, and shrimp.
eruption: (Earth science) A sudden explosion or eruption of hot material from deep within a planet or moon, erupting from the surface. On Earth, volcanic eruptions usually spew hot lava, hot gases, or ash into the air and onto the surrounding land. In colder parts of the solar system, eruptions often spew liquid water through cracks in the icy crust, as happens on Saturn’s icy moon Enceladus.
evolution: (verb: to evolve) The process by which species change over time, usually through genetic mutation and natural selection. These changes usually result in new types of organisms that are better suited to the environment than previous types. The new type is not necessarily more “evolved,” it is simply better adapted to the particular conditions in which it developed.
Exoskeleton: The hard, protective membrane that covers the outside of the body of many animals, such as insects, crustaceans, and mollusks, that do not have a true skeleton. The exoskeleton of insects and crustaceans is made mainly of chitin.
Extinct: An adjective describing a species that has no extant species.
fossil: Traces or preserved remains of ancient life. There are many different types of fossils. Dinosaur bones and other body parts are called “body fossils”. Things like footprints are called “trace fossils”. Even specimens of dinosaur dung are fossils. The process by which fossils are formed is called fossilization.
Insight: The ability to accurately and deeply understand a situation through thought alone, rather than finding solutions through experimentation.
limbs: (in physiology) An arm or leg.
Paleontologist: A scientist who specializes in the study of fossils, the remains of ancient organisms.
Specialized field: The act of concentrating or specializing in a particular interest, skill, or technique.
system: A network of parts working together to accomplish some function. For example, blood, blood vessels, and the heart are the main components of the human body’s circulatory system. Similarly, trains, platforms, tracks, road signals, and overpasses are some of the potential components of a country’s rail system. System can also apply to a process or idea that is part of some method or ordered series of steps to complete a task.
Organization: The different types of material made up of cells that make up animals, plants, and fungi. Cells within tissues function as units that perform specific functions in the body. For example, the various organs of the human body are often made up of different types of tissue.
Trilobites: A group of extinct arthropods related to modern insects.
