The document outlines a lesson plan focused on the formation of chondrites and asteroids in the early solar system. It includes objectives for students to experiment with simulations, observe meteorite samples, and understand the processes of condensation and accretion. The lesson features activities involving static electricity and magnetic forces to illustrate how dust particles coalesce into larger bodies, providing insights into the primitive materials that formed planets.

What was the Earth like before it was formed?

The super-hot core heated the mantle, which made the mantle lighter and caused it to rise up. This mantle was cooled at the ocean floor and became plates, or bedrock. These plates moved with the flow of the mantle and collided with other plates. At the boundaries where plates collided, lots of islands were formed.

How did Earth really form?

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.

How was Earth actually created?

Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.

How did we form?

Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. One of the earliest defining human traits, bipedalism -- the ability to walk on two legs -- evolved over 4 million years ago.

How did life first start on Earth?

The Earth formed more than 4 billion years ago along with the other planets in our solar system. The early Earth had no ozone layer and was probably very hot. The early Earth also had no free oxygen. Without an oxygen atmosphere very few things could live on the early Earth.

How did life actually start on Earth?

The same goes for deep-sea hydrothermal vents. These chimney-like vents form where seawater comes into contact with magma on the ocean floor, resulting in streams of superheated plumes. The microorganisms that live near such plumes have led some scientists to suggest them as the birthplaces of Earths first life forms.

How was our moon created?

The giant-impact theory is most widely accepted today. This proposes that the Moon formed during a collision between the Earth and another small planet, about the size of the planet Mars. The debris from this impact collected in an orbit around Earth to form the Moon.
