aluminum: The third most abundant metallic element in the Earth’s crust. Because it is light and soft, it is used in many items from bicycles to spaceships.
angle: The distance (usually measured in degrees) between two intersecting lines or planes at or near the point where they intersect.
Note: A phenomenon in which mental resources are concentrated on a specific object or event.
average: Term (in science) for arithmetic mean. The sum of a number group divided by the size of the group.
botany: A field of biology centered on plants. Scientists in this field are known as botanists.
Control: (n.) A part of an experiment that does not change from its normal state. Control is essential in scientific experiments. This indicates that any new effects are likely due to only part of the test that the researchers changed. For example, if a scientist is testing different types of fertilizers in a garden, they may want to leave some sections of it unfertilized as a control. The area will show how the plants in this garden grow under normal conditions. And it gives scientists something to compare experimental data with. (v.) The inclusion of unaltered or unaffected conditions in an experiment so that the results can later be compared with the results if the changes were made.
data: Facts and/or statistics collected together for analysis. They are not necessarily organized in a way that gives them meaning. For digital information (the type stored by computers), these data are typically numbers stored in binary code and represented as strings of 0’s and 1’s.
erosion: (v. erode) The process of removing rock or soil from one location on the Earth’s surface and depositing it on another. Erosion can be very fast or very slow. Causes of erosion include wind, water (including rainfall and flooding), the scouring action of glaciers, and the cycles of freezing and thawing that occur in many parts of the world.
element: Something that plays a role in a particular state or event. Contributor.
fertilizer: Nitrogen, phosphorous, and other plant nutrients added to soil, water, and foliage to promote crop growth and to replenish nutrients previously lost through use by plant roots and leaves. .
field: Research fields such as: Her field of research is biology. It is also a term used to describe any real-world environment in which some kind of research is conducted, such as the ocean, forest, mountaintop, or street. This is the opposite of artificial environments such as laboratories.
Power: external influences that can change the motion of objects, move objects closer together, or cause motions or stresses in stationary objects.
horizontal: A line or plane that runs from left to right, like the horizon when you look into the distance.
mass: A number that indicates how much an object resists acceleration and deceleration. Basically, it is a measure of how much material an object is made of.
Insecticide: A mixture of chemicals or compounds used to kill insects, rodents, and other organisms that are harmful to cultivated plants, pets, and livestock. or unwanted microorganisms that invade homes, offices, farm buildings, and other protected structures.
plastic: Any of a series of materials that are susceptible to deformation. or synthetic materials made from polymers (long strings of component molecules) that are lightweight, cheap, and resistant to deterioration.
spill: Rainwater that flows from land into rivers, lakes, and the ocean. As that water moves through the soil, it picks up some soil and chemicals that are later deposited as pollutants in rivers, lakes, and oceans.
simulate: To imitate the form or function of something to deceive in some way. For example, simulated dietary fats can trick your mouth into thinking you’re tasting real fat because they have no calories and have the same feel on your tongue. The simulated tactile sensation could trick the brain into thinking the fingers touched something, even though the hand no longer exists and has been replaced by an artificial limb.
system: A network of parts that work 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 elevated tracks are among the potential components of a country’s railway system. Systems can also apply to processes and ideas that are part of a method or ordered sequence of steps for completing a task.
tool: An object made or obtained by humans or other animals that they use to accomplish some purpose, such as to reach food, protect themselves, or groom themselves.
vegetation:Lush green plants. This term refers to a collective community of plants in an area. These usually do not include tall trees, but instead plants that are no taller than shrubs.
vertical: A term used to describe the direction of lines or planes that extend up and down, such as the vertical poles of street lamps. This is the opposite of a horizontal line running parallel to the ground.
weather: The state of the atmosphere at a local location and at a particular time. It is usually described in terms of specific characteristics such as barometric pressure, humidity, humidity, precipitation (rain, snow, ice), temperature, and wind speed. Weather constitutes a real situation that occurs anytime and anywhere. This is different from climate, which describes the conditions that tend to occur in a general area during a particular month or season.
