Understanding key vocabulary is important in reviewing for the E-LST(Science State Test). A group of educators at Cattaraugus Allegany BOCES has developed a useful website (with linked activities and demonstrations) that can help students review the vocabulary most often required for good performance on the E-LST. The website is:
benefits its survival in the environment.
2. Attract: when two objects are drawn together (two examples would be a
metal paper clip and a magnet).
3. Camouflage: a successful strategy to avoid an early death by being able
to hide in one’s surroundings.
4. Characteristic: an identifiable part of an object that becomes associated
with that object (a characteristic of a snake is that it has scaly skin.)
5. Condensation: when water changes its state from gas to liquid.
6. Conductor: a material through which an electric current moves easily
(such as, copper wire, a nail.)
7. Decomposers: organisms that break down organic matter from a
complex to a simpler form.
8. Decomposition: the process of breaking down organisms from a complex
to simpler forms.
9. Decrease: a decrease means that something lessens or gets smaller in its
mass or measurable characteristics.
10.Displacement: the amount of a fluid such as water that is forced to move
by an object floating or submerged in it.
11.Disperse: to cause something to scatter in different ways.
12.Energy: the capacity for doing work.
13.Environment: all the external factors influencing the life and activities
of people, plants and animal.
14.Erosion: the wearing away and movement of weathered rocks and soil,
usually by wind or water.
15.Evaporation: when water changes its state from liquid to gas.
16.Friction: the force that resists motion between two surfaces when they
rub against each other. (Your hands heat up when you rub them together,
that is caused by friction.)
17.Function: the work or job that something does (the job of a hammer is to
drive in a nail.)
18. Germination: When a plant or seed begins to sprout or grow.
19.Gravity: the force of attraction through which terrestrial bodies tend to
fall towards the center of the Earth.
20.Habitat: the natural environment where a plant or animal lives.
21.Heat Energy: energy produced by heat (like when an ice cube melts.)
22.Increase: when the amount of something gets larger or more
measurable in volume.
23.Inherited Trait: a characteristic of an organism that it receives from its
parent (curly hair, eye color, cleft in chin).
24. Insulator: Material through which an electric current willnot flow
(such as, rubber, wood, and plastic).
25. Life Span: the length of time an organism is expected to live.
26. Magnetism: the properties of attraction possessed by magnets.
27. Magnetic Energy: the capacity to work when magnets are used.
28. Matter (States of): solid, liquid or gas.
29. Mechanical Energy: the capacity to work generated by a machine.
30. Migration: the act or process of moving from one place to another.
31. Nutrients: chemicals that plants and animals need in order to survive.
32. Organism: any living thing.
33. Precipitation: the water (in various possible forms) that falls through the
air to strike the Earth.
34. Predator: animal that hunts and eats other animals.
35. Prey: an animal that is hunted and killed by another animal for food.
36. Process: the steps involved in an operation or cycle (egg, larva, pupa,
37. Producers: green plants are producers because they make their own
38. Property: a characteristic or attribute that helps describe a substance,
such as color, shape, size, smell and texture.
39. Repel: one of the forces of magnetism, that drives two objects apart.
40. Revolution: when something moves around one central point, as the
Earth moves around the sun.
41. Rotation: the act of spinning on one’s own axis, as a wheel turns on an
42. Runoff: when water on the Earth’s surface is unable to sink in, and
instead moves across the surface.
43. Salivating: the act of producing saliva which results from smelling, or
seeing a food or stimulus.
44. Sound Energy: the capacity to work and produce a sound (like when the
beating of a drum results in a noise.)
45. Texture: one of the properties of an object that can be determined from
its feel and/or appearance(sandpaper has a rough texture.)
46. Transformation: when an object or organism undergoes a noticeable
change in appearance or form.
47. Weathering: the breaking down of rocks due to air, wind, water,
temperature or chemical changes.
