= Thermal Energy =

Thermal energy, which is also known as heatis the vibration and movement of the atoms and molecules within substances. As an object is heated up, its atoms and molecules move and collide faster. Atoms and molecules, the smallest particles of any substance, are always in motion. The motion of thermal energy is usually not visible, but we can feel or see its effects. Thermal energy is not the same as heat. Heat is energy transferred between substances or systems due to a temperature difference between them. The amount of heat transferred by a substance depends on the speed and number of atoms or molecules in motion. The faster the atoms or molecules move, the higher the temperature, and the more atoms or molecules that are in motion, the greater the quantity of heat they transfer.

= Sun =

An example of thermal energy is the sun because the reactions taking place on it are giving off heat. The main purpose of the Sun is provision of light to living things. Light is very important to almost all living organisms. The sun is referred to as the greater light. It is the self luminous gaseous globe of heat and light around which the earth and other planets make a revolution. The gravity from the sun is what keeps the earth from flying off into space. The sun also helps with the tides, and it heats the earth making life possible.



=Model of Energy= =Experiment=

The purpose of the experiment was to see if different shapes of paper would affect how far the paper blows and what angles you have to blow the paper so it would move. The first shape of paper tested was the regular sheet of paper, when the fan was in front of the paper it didn't blow the paper so you had to hold the fan at the bottom left of right corner for it to pick up the paper and move it. The second shape of paper was the crumpled up paper ball, the fan was held in front of the paper and blew the paper without having to put it at an angle like the flat sheet of paper. The third shape of paper was a frog origami shape made and laid down flat, when the fan blows the paper from the front it doesn’t go very far but when you hold it in the bottom left of right corner it is able to move father. These experiments have proved that to blow certain shapes of paper you have to blow it at an angle and also different shapes of paper travel different distances when blown.
