1. The Water Cycle
Precipitation – liquid water or ice that falls back to Earth’s surface. Rain is precipitation.
Evaporation – the change in phase of liquid water to water vapor. Example would be water from oceans or rivers is evaporated into the atmosphere as water vapor.
Condensation – water vapor in the air gets cold and changes back into liquid and forms clouds.
Transpiration – the process by which plants lose water out of their leaves. Gives evaporation help in getting the water vapor back up into the air.
Infiltration – the movement of surface water into rock or soil through cracks and pore spaces.
Sun – the sun heats up water on land, oceans, and lakes and causes evaporation
Run-off – when precipitation gathers in streams and rivers and flows back down to the oceans, seas, and lakes

3. What is energy? Energy is the ability to do work.
Energy makes change; it does things for us.

4. How Can energy be transferred?
Conduction
Convection
Radiation

5. Types of Energy
Chemical Energy - energy stored in the bonds of atoms and molecules.
Mechanical Energy – energy stored in objects by the application of a force.

6. Types of energy
Nuclear Energy – energy stored in the nucleus of an atom – the energy that holds the nucleus together.
Gravitational Energy – the energy of position or place. A rock resting at the top of a hill contains gravitational potential energy.

7. Types of energy
Electrical Energy – the movement of electrical charges.
Radiant Energy – electromagnetic energy that travels in transverse waves.

8. Types of energy
Thermal energy – heat energy, is the internal energy in substances. Geothermal energy is an example of energy.
Motion energy – the movement of objects and substances from one place to another. Wind
Sound energy – the movement of energy through substances in longitudinal waves. Sound is produced when a force causes an object or substance to vibrate.

9. Energy transformations
An energy transformation is a change from one form of energy to another form of energy. This is sometimes called an energy conversion.
