What are some solar system projects for kids?

To build a three-dimensional solar system model, use different colored balloons to represent the various celestial bodies. For example, use a yellow balloon for the sun and a red one for Mars. Inflate the balloons to different sizes depending on the planet each one represents, and use a piece of yarn to hang them in line starting from the sun to the last planet.\nA hanging solar system foam model involves representing the eight planets and the sun using different-sized Styrofoam balls bought from an arts-and-crafts supply store. With the largest ball representing the sun, assign planet names t..

Why does solid sodium conduct electricity?

Sodium is a metal. Its outermost shell or energy level has only one electron. Each sodium atom is surrounded by eight other sodium atoms, each of which has one electron in its outermost energy level. The close proximity of the atoms in solid sodium leads to the sharing of space between the atoms and therefore the sharing of the outermost electrons. The central sodium atom shares electrons with its eight neighbors and each neighbor in turn shares electrons with its eight neighbors and so on.\nThe electrons are able to detach themselves from their parent atom and move around freely. They are sai..

Why is my blood thin?

New Health Guide explains that platelets can be destroyed more quickly than they reproduce. This problem can occur when the liver removes too many platelets or the bone marrow does not produce the sufficient amount.\nAccording to New Health Guide, some of the most common symptoms include continual bleeding instead of scabbing of wounds, nosebleeds, bleeding of gums and frequent bruising of the skin. Severe thinning of blood can also result in vomiting of blood and the presence of blood in urine. New Health Guide recommends consulting with a physician if these symptoms are experienced for prope..

When were the first planets around other sun-like stars discovered?

After the 1992 discoveries, a third planet was discovered and confirmed in 1994, followed by discoveries in 1995 and the first discovery of a multiple planetary system in 1999.\nIn addition to confirmed discoveries, NASA's Kepler mission catalogues possible planetary objects, identifying over 2,900 potential planets as of early 2014.\nScientists search for exoplanets using techniques in direct imaging, transit observations, the Doppler method, astrometry, pulsar timing and polarimetry.

How do dinoflagellates obtain nutrition?

Phagotrophy is a type of intracellular digestion and osmotrophy involves osmosis causing the uptake of organic compounds after dissolving them. Dinoflagellates are very common in aquatic ecosystems, about half are heterotrophic, and the other half are photosynthetic. Due to the diversity among this type of protest, they are common in freshwater and marine ecosystem zooplankton and phytoplankton. They are also in sea ice and benthic environments.

How do you convert 47 centimeters to inches?

Learn the conversion rateLearn how many centimeters are in each inch and vice versa. There are approximately 2.54 centimeters (cm) in each inch (in), which creates the equation 2.54cm = 1in. Because 1/2.54 is approximately 0.39, you can also write 1cm = 0.39in.\n\nThis tells you that there are a little more than 2.5 centimeters in every inch and that 1 centimeter is about 0.4 or 2/5 of an inch.Convert centimeters to inchesTo convert centimeters to inches, create an equation that cancels the centimeter unit and replaces it with inches.\n\nFor example, 47cm * 0.39in / 1cm = 18.33in, because 1cm/..

How long does it take to orbit the Sun?

Mercury, the closest planet to the Sun, orbits the Sun in 88 Earth days, and Venus, which is the planet second closest to the Sun, orbits it in 224.7 Earth days. Mars, the fourth planet from the Sun, completes an orbit around the Sun in about 1.8 Earth years, and Jupiter orbits the Sun in 12 Earth years. Though it is the fifth planet from the Sun, it is so far away from the star that it's considered the first of the outer planets. The asteroid belt intervenes between Mars and Jupiter.\nSaturn orbits in 29.45 Earth years, and it takes Uranus 84 Earth years to complete an orbit. Neptune is ..

What is the triple product rule?

According to TutorVista, the product rule serves as a way to differentiate functions that are being multiplied by one another. When two functions are multiplied together, the product's derivative equals the first function multiplied by the derivative of the second, added to the second function multiplied by the derivative of the first function.\nProduct rules and derivatives can be difficult to analyze and prove, but the triple product rule makes finding solutions a bit easier. Using the triple product rule, it is possible to find the quotients of partial derivatives, which are easier to ..
