The Periodic Table of Elements shows all the elements known to mankind. For example, gold is one element that is used to make jewelry and other things.
For example, there is millions of workers in a building. They all get assigned to do a different job like collect sunlight and turn it into sugar if it was in a plant or even fight off diseases or even bacteria from a door handle or something. Cells are the building blocks of life.
Mars is the closest planet to Earth and is the fourth planet in the Solar System. It is made of red rock that is kind of like hard red, orange clay. Mars is cool!!!
The water cycle is a couple of steps that water goes through to get clean. The first step is evaporation, the water gets heated by the Sun and turns into water vapor. The vapor floats up into the sky and gets colder and colder. The water gets cold and turns into clouds...
The clouds are called condensation and they give of rain that is called precipitation. The water eventually gets down to the ocean and the cycle starts over again!!!!!!!!
