Cyberwellness 2 - Handling Inappropriate Content
I never ever seen anything online that made you afraid, uncomfortable or feel excited and yet guilty because you sensed that it was wrong. I discern if the content on the Internet is inappropriate by asking myself is the content asking me to hurt myself or other. if the content on the Internet is inappropriate i would tell my parent.

air foil shape

airfoil-shaped body moved through a fluid produces a force perpendicular to the motion called lift. Subsonic flight airfoils have a characteristic shape with a rounded leading edge, followed by a sharp trailing edge, often with asymmetric camber. Foils of similar function designed with water as the working fluid are called hydrofoils. (information taken from wikipedia)
rotor
A rotor is the rotating part of a helicopter which generates an aerodynamic Lift (force). The helicopter rotor, also called the rotor system, usually refers to the helicopter's main rotor which is mounted on a vertical mast over the top of the helicopter, although it can refer to the helicopter's tail rotor as well. A helicopter's rotor is generally made up of two or more rotor blades, although several earlier helicopters had a rotor with a single main rotor blade. The main rotor provides both lift and thrust, while the tail rotor provides thrust to compensate for the main rotor's torque. (information taken from wikipedia)
propeller
propeller is a type of fan which transmits power by converting rotational motion into thrust. It can be used to drive an aircraft ship, or the fluid within a pump. It consists of one or more blades about a central shaft and operates like a rotating screw or wing. A pressure difference between the forward and rear surfaces of the airfoil-shaped blade is produced and air or water accelerated behind the blade. Propeller dynamics can be modeled by both Bernoulli's principle and Newton's third law. (information taken from wikipedia)
sun
The Sun is the star at the center of the Solar System. The Earth and other matter (including other planets, asteroids, meteoroids, comets, and dust) orbit the Sun, which by itself accounts for about 99.86% of the Solar System's mass. The mean distance of the Sun from the Earth is approximately 149.6 million kilometers (93.0 million miles), and its light travels this distance in 8 minutes and 19 seconds. This distance varies throughout the year from a minimum of 147.1 million kilometers (91.4 million miles) on the perihelion , to a maximum of 152.1 million kilometers (94.5 million miles) on the aphelion . Energy from the Sun, in the form of sunlight, supports almost all life on Earth via photosynthesis, and drives the Earth's climate and weather. The Sun consists of hydrogen (about 74% of its mass, or 92% of its volume), helium (about 24% of mass, 7% of volume), and trace quantities of other elements, including iron, nickel, oxygen, silicon, sulfur, magnesium, carbon, neon, calcium, and chromium.
The Sun has a spectral class of G2V. G2 means that it has a surface temperature of approximately 5,780 K (5,510 °C) giving it a white color, which often appears as yellow when seen from the surface of the Earth because of atmospheric scattering. It is this scattering of light at the blue end of the spectrum that gives the surrounding sky its color.[ The Sun's spectrum contains lines of ionized and neutral metals as well as very weak hydrogen lines. The V (Roman five) in the spectral class indicates that the Sun, like most stars, is a main sequence star. This means that it generates its energy by nuclear fusion of hydrogen nuclei into helium. There are more than 100 million G2 class stars in our galaxy. Once regarded as a small and relatively insignificant star, the Sun is now known to be brighter than 85% of the stars in the galaxy, most of which are red dwarfs (information taken from wikipedia)

eye

Eyes are organs that detect light, and send signals along the optic nerve to the visual and other areas of the brain. Complex optical systems with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in cnidaria, molluscs, chordates, annelids and arthropods.
The simplest "eyes", such as those in unicellular organisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment.

Cyberwellness - Cyber Addiction (Pupils' Response)
my favourite computer game is club penguin. I spent 1 hour playing computer games but sometimes i go down and play table tennis with my friend. it does not affected my daily routine. i can do some sport like tennis. I would tell to take a break and do some sport friend who is a game addict

Pupils' Response 19 - Effects of Preventive Measures on Pupils
I think of the school's preventive measures for H1N1 such as temperature-taking, no assembly in the hall, cancellation of remedial lessons, CCA and other activities is helping in prevent the spread of h1n1. the cancellation of activities have not affected me. I think the school is less interesting now because we are not allow to go to many parts of the the school. i study during my free time. my activities outside school are not affected.
