Material Noun

---

[muh-teer-ee-uhl]

Back

Material

---

The matter from which a substance is or can be made, possessing distinct properties based on its composition.

---

Example: Steel beams are used in construction for their strength and durability.

Properties Noun

---

[prop-er-teez]

Back

Properties

---

The characteristic physical and chemical qualities that can be used to identify and describe a specific material or substance.

---

Example: Lists different physical properties such as mass and conductivity, but doesn't explain their significance or how they identify materials.

Front

Density Noun

---

[den-si-tee]

Back

Density

---

A fundamental physical property of a material that measures the amount of mass contained within a specific unit of volume.

---

Example: Objects with different densities float or sink in water, showing how mass and volume affect density.

Front

Displacement method Noun

---

[dis-pleys-muhnt meth-uhd]

Back

Displacement method

---

A technique for measuring an object's volume by observing the amount of fluid it pushes aside when fully submerged.

---

Example: An object in water pushes fluid aside, showing how its volume is measured.

Front

Natural material Noun

---

[nach-er-uhl muh-teer-ee-uhl]

Back

Natural material

---

Any physical matter obtained from plants, animals, or the ground that has undergone very little human-made modification.

---

Example: This image shows natural materials like wood, rock, and plants, which are minimally modified by humans.

Front

Synthetic material Noun

---

[sin-thet-ik muh-teer-ee-uhl]

Back

Synthetic material

---

A material created from natural resources that have been chemically changed in a laboratory or factory to form new substances.

---

Example: Monomers chemically bond to form polymers, creating synthetic materials like fibers.

Front

Technology Noun

---

[tek-nol-uh-jee]

Back

Technology

---

The application of scientific knowledge for practical purposes, especially in industry, to create tools, machines, and processes.

---

Example: A generator uses magnetic fields and a wire coil to produce electricity, showing technology in action.

Front

Chemical reaction Noun

---

[kem-i-kuhl ree-ak-shuhn]

Back

Chemical reaction

---

A process that involves the rearrangement of atomic bonds in substances, resulting in the formation of new, different substances.

---

Example: The image shows how hydrogen and oxygen atoms rearrange to form water in a chemical reaction.

Front

Reactants Noun

---

[ree-ak-tuhnts]

Back

Reactants

---

The initial substances that are present at the beginning of a chemical reaction and are consumed during the process.

---

Example: The image shows hydrogen and oxygen as reactants combining to form water.

Front

Products Noun

---

[prod-uhkts]

Back

Products

---

The new substances that are created as the result of the atomic rearrangement that occurs during a chemical reaction.

---

Example: The image shows water as the product formed when hydrogen and oxygen react.
