Students become planets during this activity students will pretend to be particles of various masses, each having their own gravity floating around in space each 'particle' is drawn towards other 'particles', eventually forming a planet set up: 20 min activity and discussion: 1 1/2 hr clean up.
Earth formed at least 453 billion years ago gravity pulled material from a nebula of rock, gas, and dust into a spinning disk the sun formed in the center, and the disk then coalesced into the planets young earth contained seas of magma and had regular asteroid impacts. Earth is the planet we live on it is the third planet from the sunit is the only planet known to have life on it lots of scientists think the earth formed around 45 billion years ago.

One of the oldest questions for mankind is how the earth was formed however, no one has an exact answer first by the best estimates it occurred over 4 billion years ago before any life appeared so there are no eyewitness accounts and other pieces of evidence.

The most accepted theory on how the creation of the solar system is core accretion, which took several steps over some 46 billion years the collapsing of gravity caused the material in a nebula to spin that created the sun, with smaller particles fanning out and forming planets such as earth.Download
