Neon By: Ariana Neon was discovered by Morris Traver‚ and William Ramsay in 1898. Neon is a gas that produces a colored glow when excited by electricity passing through a glass tube in which the glass is confined. But you may wonder how are these neon lights even made? Well‚ the Neons gas is inserted into glass tubing using a thin pipe then the pipe is quickly removed‚ and the glass is fused at the end. The neon tube produces the light when an electrical current bombards the gas atoms with electrons

Activity 1 – Water Holding Capacity & Capillary Action of Soil 1. Grain size and the amount of air space between particles. 2. Water-holding capacity determines the amount of water a soil is capable of holding. Since water is a necessity of any agricultural endeavor it is important for a soil to have a good water holding capacity. 3. We’d add humus because it has the highest water-holding capacity. 4. It would benefit plants in a dry climate because it could easily take groundwater

The modern atomic theory was developed by many scientists‚ such as Neil Bohr‚ Democritus‚ James Chadwick and John Dalton. Each of these intelligent scientists have found different discoveries in their research with the atom. Why has scientific understanding of the atom changed over time? This would be because each scientist has had a different approach and has discovered new understandings from their research. Without these men researching and experimenting‚ we would not know all of the different

The Atomic Model has changed over time‚ as the years‚ decades‚ and centuries go by we get a better understanding of the atom and what it looks like. The Atomic Model has changed drastically based on the understanding we have on it‚ each new model has added more information to what we know about it‚ making it easier for scientists and the world to understand. The Atomic Model is a very important part of Science and Chemistry‚ it helps explain the structure and what is inside the atom‚ the particle

The Progress of the Atomic structure Different theories about the atomic structure were introduced over time. These theories changed as a result of development of different experiments. Leucippus was the first to introduce the theory of atomism‚ however he didn’t write about his theories in detail. However‚ Democritus‚ his student wrote about the theory of atoms in detail. He theorised that everything was composed of atoms and that atoms are solid and indestructible. He also had a theory that

Fifteen to twenty billion years ago‚ the universe arose as a cataclysmic eruption of hot‚ energy-rich sub-atomic particles. Within seconds‚ the simplest elements (hydrogen and helium) were formed. As the universe expanded and cooled‚ material condensed under the in-fluence of gravity to form stars. Some stars became enormous and then exploded as supernovae‚ releasing the energy needed to fuse simpler atomic nuclei into the more complex elements. Thus were produced‚ over bil-lions of years‚

Democritus was an Ancient Greek pre-Socratic philosopher of Ancient Greece. He along with Leucippus were atomic theorists who proposed during the fifth century B.C that 1. Matter is composed of atoms separated by empty space by which atoms move. 2.Atoms are solid‚ homogeneous‚ indivisible‚ and unchanging. Democritus knew that if he took a rock and chisel it in half‚ that both halves would characteristically have the same properties as the whole. He rationalized that if he was to continue to cut the

The Egg-Drop Device Process The process of dropping an egg is more complex than a normal person would believe. The egg-dropping process requires knowledge of history‚ engineering‚ and mathematics and physics. To fully understand how an egg drops‚ the knowledge of the history of physics‚ the engineering behind a device‚ and the mathematics and physics of free-fall is needed. Classic physics originates in Ancient Greece. The theories Thales‚ the first physicist‚ designs gives the discipline of physics
