An experiment to determine the oxygen produced in relation to the distance of the light source

Mars continues to dazzle in the November sky Mars continues to put on a great show these November evenings. Although the Red Planet officially reached opposition way back in July, it has remained one of the most conspicuous sights in the night sky ever since. Researchers are 3D-printing fake Moon dust into useful hardware A future on the Moon To support a potential future lunar base, researchers at the European Space Agency ESA have 3D printed and baked fake Moon dust into screws, gears, and even a coin. Both private and government space agencies have expressed se

Sol is also used by planetary astronomers to refer to the duration of a solar day on another planet, such as Mars.

A mean Earth solar day is approximately 24 hours, whereas a mean Martian 'sol' is 24 hours, 39 minutes, and Solar deity Solar deities play a major role in many world religions and mythologies.

In the New Empire period, the Sun became identified with the dung beetlewhose spherical ball of dung was identified with the Sun. In the form of the Sun disc Atenthe Sun had a brief resurgence during the Amarna Period when it again became the preeminent, if not only, divinity for the Pharaoh Akhenaton.

It was adopted as the Sabbath day by Christians who did not have a Jewish background. The symbol of light was a pagan device adopted by Christians, and perhaps the most important one that did not come from Jewish traditions.

In paganism, the Sun was a source of life, giving warmth and illumination to mankind. It was the center of a popular cult among Romans, who would stand at dawn to catch the first rays of sunshine as they prayed. The celebration of the winter solstice which influenced Christmas was part of the Roman cult of the unconquered Sun Sol Invictus.

Christian churches were built with an orientation so that the congregation faced toward the sunrise in the East. The heavy elements could most plausibly have been produced by endothermic nuclear reactions during a supernova, or by transmutation through neutron absorption within a massive second-generation star.

The energy of this sunlight supports almost all life [c] on Earth by photosynthesis[48] and drives Earth's climate and weather.

The Sun does not have a definite boundary, but its density decreases exponentially with increasing height above the photosphere.

This differential rotation is caused by convective motion due to heat transport and the Coriolis force due to the Sun's rotation.

In a frame of reference defined by the stars, the rotational period is approximately Viewed from Earth as it orbits the Sun, the apparent rotational period of the Sun at its equator is about 28 days.

Sunlight The solar constant is the amount of power that the Sun deposits per unit area that is directly exposed to sunlight. When measuring all the photons emitted, the Sun is actually emitting more photons in the green portion of the spectrum than any other.

Despite its typical whiteness, most people mentally picture the Sun as yellow; the reasons for this are the subject of debate. Molecules in stars The Sun is composed primarily of the chemical elements hydrogen and helium.

At this time in the Sun's life, they account for Originally it would have contained about Over the past 4. The proportions of metals heavier elements is unchanged.

Heat is transferred outward from the Sun's core by radiation rather than by convection see Radiative zone belowso the fusion products are not lifted outward by heat; they remain in the core [68] and gradually an inner core of helium has begun to form that cannot be fused because presently the Sun's core is not hot or dense enough to fuse helium.

In the future, helium will continue to accumulate in the core, and in about 5 billion years this gradual build-up will eventually cause the Sun to exit the main sequence and become a red giant.

These meteorites are thought to retain the composition of the protostellar Sun and are thus not affected by settling of heavy elements.

The two methods generally agree well. Hydrogen fuses into helium which cannot currently be fused at this point in the Sun's life. The fusion process releases energy, and the helium gradually accumulates to form an inner core of helium within the core itself. Radiative zone — Convection cannot occur until much nearer the surface of the Sun.

Tachocline — the boundary region between the radiative and convective zones.

Photosphere — the deepest part of the Sun which we can directly observe with visible light. Because the Sun is a gaseous object, it does not have a clearly-defined surface; its visible parts are usually divided into a 'photosphere' and 'atmosphere'.The basic requirements for life support are: Breathing Mix: an atmosphere to breath, or the crew will rapidly suffocate.

Oxygen must be added as it is consumed and carbon dioxide removed as it is exhaled. Humidity must be maintained at a confortable level. This 1, LED unit of nm and nm was used by someone for a relative who has a case of Alzheimer's.

I believe the setting was adjusted to about W and I believe they both used it consistently for 15 minutes twice a day. barnweddingvt.com is for anyone who wants to learn more about astronomy events, cosmology, planets, galaxies, asteroids, astrophotography, the Big Bang, black holes.

Unfortunately, there is a massive confusion between causality and equations. Much of what passes for “theoretical” science is based upon the false subterranean assumption that the equations CAUSE reality.

Demonstrating Oxygen Evolution during Photosynthesis using Pondweed Watching gas bubble up from a pondweed as it photosynthesises can be a great demonstration or student practical.

When placed closer to a light source, the rate of bubbling will speed up, and as the pondweed is taken further away, the bubbles will slow down again - an . Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide, affected the rate of photosynthesis.

The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min).
