An example is Pinatex, a pineapple-based leather that is manufactured from the cellulose fibers of pineapple leaves. It is an environmentally friendly alternative to traditional leather due to its sustainability and adaptability. Additionally its lightweight, resilient and biodegradable nature has made it very popular for new and innovative ...
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
Definition [ edit ] The word pedigree is a corruption of the Anglo-Norman French pé de grue or "crane's foot", either because the typical lines and split lines (each split leading to different offspring of the one parent line) resemble the thin leg and foot of a crane [ 3 ] or because such a mark was used to denote succession in pedigree charts.
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
In the Finale of Act I of The Pirates of Penzance, the Pirates sing, "Pray observe the magnanimity we display to lace and dimity".; In the conclusion of Paul Selver's translation of The Insect Play by brothers Karel and Josef Čapek, a group of school children sing: "As I went down to Shrewsbury Town, / I saw my love in a dimity gown: / And all so gay I gave it away, / I gave it away—my ...
More intense retting separates the fibre bundles into elementary fibres, which can be several centimetres long. Often bast fibres have higher tensile strength than other kinds, and are used in high-quality textiles (sometimes in blends with cotton or synthetic fibres), ropes, yarn, paper, composite materials and burlap.
Typically, display behaviour is used for courtship between two animals and to signal to the female that a viable male is ready to mate. [2] In other instances, species may make territorial displays, in order to preserve a foraging or hunting territory for its family or group. A third form is exhibited by tournament species in which males will ...
