In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
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.

Genera such as Rhynia have a similar life-cycle but have simple tracheids and so are a kind of vascular plant. [44] It was assumed that the gametophyte dominant phase seen in bryophytes used to be the ancestral condition in terrestrial plants, and that the sporophyte dominant stage in vascular plants was a derived trait.

All organisms follow a specific sequence in their development, [9] beginning with gestation and ending with death, which is known as the life cycle. Events in between usually include birth , childhood , maturation , reproduction , and senescence , and together these comprise the life history strategy of that organism.
The Google Science Fair was a worldwide (excluding Cuba, Iran, North Korea, Sudan, Myanmar/Burma, Syria, Zimbabwe and any other U.S. sanctioned country [1]) online science competition sponsored by Google, Lego, Virgin Galactic, National Geographic and Scientific American. [2] [3] [4] It was an annual event spanning the years 2011 through 2018.
It included 46 events, a street fair and, on its first day, the one-day World Science Summit at Columbia University. The Festival was attended by 120,000 people. [7] It featured several different kinds of presentations: science events for a general audience, a cultural program focusing on art inspired by science, and a youth and family program. [8]
