# When we put something on a fire, it become hot. It becomes hot by absorbing the heat from the fire. How hot it becomes depends on the the material and the mass of the object. Every material absorbs heat differently. This depends on how the molecules are arranged in the object.

* '''Developmental Questions (What discussion questions)'''<br>
#How does the water become more hot in the first video?
#We have seen that energy means ability to do work. When we say energy we usually think of movement, potential energy, kinetic energy, light, etc.

#What about heat? Heat is a form of energy. When we rub our hands together, drag an object over another or even sharpen a tool, we will notice that heat is generated. Our hands will get warm and the tools will also become very hot.

#Why does this happen? Molecules inside an object are always moving and when their movement is increased, their energy is increased. And this is what is felt as heat. We can see that heat is a form of energy.
