What is cast in science?
The California Science Test (CAST) is part of California's system of assessments called the California Assessment of Student Performance and Progress (CAASPP). The CAST measures what students know and can do using the California. Next Generation Science Standards, which focus on understanding the.
What is a cast in biology?
Cast: 1) A protective shell of fiberglass, plastic, or plaster, and bandage that is molded to protect broken or fractured limb(s) as it heals. 2) An abnormal mass of dead cells that forms in a body cavity. For example, cases of cells that form in the tubules of the kidneys are sometimes detected in urine samples.
What does cast mean?
to give or deposit (a vote) to select (actors) to play parts in (a play, film, etc) to shape (molten metal, glass, etc) by pouring or pressing it into a mould.
What does cast mean fossils?
Noun. cast fossil (plural cast fossils) A fossil formed when an animal, plant, or other organism dies, its flesh decays and bones deteriorate due to chemical reactions; minerals gradually enter into the cavity, resulting in a cast, which is in the general form of the original organism.
What are casts and molds?
We find molds where an animal or plant was buried in mud or soft soil and decayed away, leaving behind an impression of their bodies, leaves, or flowers. Casts are formed when these impressions are filled with other types of sediment that form rocks, which take the place of the animal or plant.
What is a cast and mold fossil?
Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment. The mineralized impression of the organism left in the sediment is called a mold. The mineralized sediment that fills the mold recreates the shape of the remains. This is called a cast.
What is a cast microbiology?
Urinary casts are tiny tube-shaped particles that can be found when urine is examined under the microscope during a test called urinalysis . Urinary casts may be made up of white blood cells, red blood cells, kidney cells, or substances such as protein or fat.
What is molds and cast?
We find molds where an animal or plant was buried in mud or soft soil and decayed away, leaving behind an impression of their bodies, leaves, or flowers. Casts are formed when these impressions are filled with other types of sediment that form rocks, which take the place of the animal or plant.
What is cast example?
The definition of a cast is something formed in a certain way, or the company of a play. An example of cast is what one wears on a broken limb. An example of cast is all of the actors and actresses in a Broadway production.
What is cast in education?

What are molds and casts?
We find molds where an animal or plant was buried in mud or soft soil and decayed away, leaving behind an impression of their bodies, leaves, or flowers. Casts are formed when these impressions are filled with other types of sediment that form rocks, which take the place of the animal or plant.
What is cast in paleontology?
Casts are replicas of the shell or bone that are formed from external or internal molds. Casts can be produced naturally, but paleontologists can also produce casts from molds with latex rubber or even modeling clay. These artificial casts can provide extra information about the fossils under study.
What is a natural cast?
Natural casts are formed when minerals are deposited within the mold. Casts can also be synthetically created when the molds are filled or covered with synthetic material, such as latex or plaster of paris, to generate a replica of the organism.
What is casting and its types?
Casting manufacturing is a process in which liquefied material, such as molten metal, is poured into the cavity of a specially designed mold and allowed to harden. After solidification, the workpiece is removed from the mold to undergo various finishing treatments or for use as a final product.
How are cast fossils created?
Sometimes when an animal dies and its body decays, it can leave an imprint in the sediment. If this imprint fills in with minerals from sediment and groundwater, it can harden to form a fossil. This fossil is called a cast fossil. The fossilized imprint is called a mold fossil.
Is a footprint a mold or a cast?
An imprint or the natural cast of a footprint in rock is an example of a mold fossil and a trace fossil, while a mineral deposit in the shape of a shell is an example of a cast fossil and a body fossil. In rare cases, organisms, or parts of organisms, are entirely preserved.
What do casts mean in urine?
Urinary casts are microscopic clusters of urinary particles, such as cells, fat bodies, or microorganisms, wrapped in a protein matrix and found in the urine. Urinary casts serve as clinical indicators of kidney condition and can be assessed to determine the functioning of the kidneys.
Where are casts formed?
Casts are cylindrical bodies formed either in the distal convoluted tubules or the collecting ducts of the kidney.
What is cast material?
Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay.
What does the cast function do?
The Cast() function is used to convert a data type variable or data from one data type to another data type. The Cast() function provides a data type to a dynamic parameter (?) or a NULL value.
What is cast in high school?
CAST Schools (The Centers for Applied Science and Technology) is a 501(c)(3) nonprofit organization with a network of tuition-free, industry-led, career-themed high schools in San Antonio and one pre–K through 12th academy.
What is a mold vs cast?
A mold is an art form that precedes a cast. A cast is made by filling the casting material into or onto a mold. A cast can be made with the same materials that are used in making a mold. A cast is a final product.
What does a cast show about an organism?
A mold forms when the hard part of an organism, such as a shell, is buried in sediment. Later, water carrying dissolved minerals may seep into the empty space of a mold. If the water deposits the minerals there, the result is a cast, a solid copy of the shape of an organism.
What is casting in chemistry?
Casting is the act of pouring liquid material into the cavity of a mold. After a period of time, this liquid will cure via chemical reaction or cooling. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
What is the process of casting?
Casting processes involve the use of molten material, usually metal. This molten material is then poured into a mould cavity that takes the form of the finished part. The molten material then cools, with heat generally being extracted via the mould, until it solidifies into the desired shape.
Are fossils casts?
Fossils form in special cases when plants and animals are buried in mud or other soft soils. If they don't decay right away, they can be compressed by many layers of sediment over thousands or millions of years and preserved as a fossil. The two main types of fossils are molds and casts.
What are blood cell casts?
Red blood cell casts mean there is a microscopic amount of bleeding from the kidney. They are seen in many kidney diseases. Renal tubular epithelial cell casts reflect damage to tubule cells in the kidney.
What are casts made of?
Most casts are made of fiberglass. Fiberglass is a kind of plastic that is moldable and dries hard. Some fiberglass casts are waterproof. Less often, casts are made of plaster of paris.
Why are casts formed?
Casts are the result of solidification of material (protein) in the lumen of the kidney tubules, more specifically in the nephron. Once formed, these molds (or casts) of the tubule are eliminated via the urine and may be seen in the urine sedi- ment.
What is metal casting?
Metal casting is the process of making objects by pouring molten metal into an empty shaped space. The metal then cools and hardens into the form given to it by this shaped mold. Casting is often a less expensive way to manufacture a piece compared with machining the part out of a piece of solid metal.
