​​Bark: This is the protective outer layer of a tree,.
Bulking agent: In the context of humans, a substance, such as cellulose, that adds volume to the material in the digestive system.
Carbon-based: A substance or compound contains carbon as its primary element.
Cell walls: These are rigid structures that surround the cells of plants, fungi, and some bacteria, providing support and protection.
Cellophane: This is a transparent, thin film made from cellulose, often used as a packaging material.
Composite: A material made up of two or more different substances that are combined to create new properties or characteristics.
Fibrous: Something that has a thread-like structure. In the context of wood, it refers to the arrangement of cellulose fibers within its structure.
Grains: In the context of wood, grains refer to the direction and pattern of fibers within the wood.
Matrix: It’s the surrounding substance or structure in which something is embedded or enclosed.
Organic compounds: Chemical compounds that contain carbon atoms bonded to other elements such as hydrogen, oxygen, nitrogen, etc.
Porous: It means having small holes or spaces that allow fluids or air to pass through. In the context of wood, it refers to its ability to absorb and release moisture.
Structural tissue: The specific type of tissue in plants that provides support and structural integrity.
Wood pulp: This is a fibrous material derived from wood, primarily used in the production of paper.

Knock on Wood

The most popular choice for indoor basketball courts, hard maple flooring can be found in most NBA stadiums and premier NCAA arenas. Hard maple is a dense wood with fine fibers, making it particularly resistant to splintering. The wood’s tightly packed grains also yield a smooth surface with no room for dirt and grime to hide. As a result, hard maple courts offer exceptional durability and require little maintenance.

What is Wood?

Wood is a porous and fibrous structural tissue found in the stems and roots of trees, and other some plants. It is an organic material, a natural composite of cellulose fibers which are strong in tension embedded in a matrix of lignin which resists compression. In a living tree lignin performs a support function, allowing trees to stand up.

Wood has been used for thousands of years for fuel, as a construction material, for making tools and
weapons, furniture and paper.


What is Organic Material?

Organic material refers to the large pool of carbon-based compounds found within natural and engineered environments. It is matter composed of organic compounds that has come from the remains of living things such as plants and animals and their waste products in the environment. Organic molecules can also be made by chemical reactions that don't involve life. Organic matter is very important in the movement of nutrients in the environment and plays a role in water retention on the surface of the planet.

What is Cellulose?

Cellulose is an organic (carbon based) compound with the formula, C 6 H 10 O 5 (six Carbon atoms join with ten Hydrogen atoms and five Oxygen atoms). The cellulose content of cotton fiber is 90% that of wood is 40–50%. Cellulose for industrial use is mainly obtained from wood pulp and cotton. It is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane.


In humans, cellulose acts as a bulking agent for feces and is often referred to as "dietary fiber".

What is Lignin?

Lignin is a type of organic compound that forms important structural materials in the support tissues of plants. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Lignin does not dissolve in water.

  1. Right Sizing the Court
    a.         What is the length & the width of a standard court?
    b.         Who is you favorite player?
    c.          What is the ratio in height between your favorite player and yourself?
    d.         How big (length & width) should the court be so that you would have the same proportional relationship to the court as your favorite
