There are many forms of energy, but they can all be put into two categories: kinetic and potential. Kinetic energy is motion of waves, electrons, atoms, molecules, substances, and objects. Potential energy is stored energy and the energy of. unrenewable

When the plankton died, they sank to the bottom of the sea or lake. In the water, they didn't decay completely. All of the dead planktons mixed with the mud and made rich organic matter, similar to peat. Over time, pieces of dirt, sand and mud cover the organic matter. More time passed and much more sand covered the organic matter. The heavy weight of the sand compressed the organic matter. As more sand build up over millions of years, the pressure on the organic matter increased-making it even more compact. Over time, the layers of sand formed sedimentary rock above the original layer of organic matter(dead plankton mixed with mud). Pressure from the layers of rock and heat from the Earth(200-300 degrees) gradually broke down the organic matter into oil and gas. Then people gather them under the sea or lake.]]> 2017-11-22 09:45:23 UTC https://padlet.com/j013675/29zslzjpvkyq/wish/209379932 Products from oil j013675 https://padlet.com/j013675/29zslzjpvkyq/wish/209390415 Floor wax

Where else haven’t we looked? Water! Energy from moving water is usually called hydro power.

When a dam is put on a river, it may interrupt the natural path of some fish. Hydro power plants install fish ladders to help fish swim upstream to reproduce. Some hydro power plants have fish lifts (elevators) instead. ]]> 2017-11-26 05:35:00 UTC https://padlet.com/j013675/29zslzjpvkyq/wish/210100962 Whose kite experiment helped scientists understand the principles of electricity? j013675 https://padlet.com/j013675/29zslzjpvkyq/wish/210101272 Benjamin Franklin.]]> 2017-11-26 05:42:22 UTC https://padlet.com/j013675/29zslzjpvkyq/wish/210101272 j013675 https://padlet.com/j013675/29zslzjpvkyq/wish/210106863 The other important thing that we need to know to understand electricity is that everything in the universe is made of tiny, tiny things called neutrons, protons and electrons.]]> 2017-11-26 07:35:26 UTC https://padlet.com/j013675/29zslzjpvkyq/wish/210106863 j013675 https://padlet.com/j013675/29zslzjpvkyq/wish/210107595  They are made up of tiny parts called neutrons, protons, and electrons.
