CHAPTERRESOURCESCHAPTERRESOURCES
Energy from sunlight is transferred to plantsand then to animals.
Electromagnetic energy from the Sun is absorbed by the grass, which changes it into chemical energy.
As the cow eats the grass, it gains chemical energy stored in the grass. The cow can use some of this energy to produce milk.
The person gains chemical energy by eating foods such as yogurt, which is made from milk.

6.3.a Students know energy can be carried from one place to another by heat flow or by waves, including water, light and sound waves, or by moving objects.
6.3.d Students know heat energy is also transferred between objects by radiation (radiation can travel through space).
6.4.b Students know solar energy reaches Earth through radiation, mostly in the form of visible light.

6.3.c Students know heat flows in solids by conduction (which involves no flow of matter) and in fluids by conduction and by convection (which involves flow of matter).
6.4.d Students know convection currents distribute heat in the atmosphere and oceans.

Conduction transfers energy by direct contact.
Energy from the cocoa is transferred to the mug,to the gloves, and then to the person’s hands.

conduction
convection
density
convection current
CHAPTERRESOURCESCHAPTERRESOURCES
Convection transfers energy by the motion of a gas or liquid. Less dense air rises, and denser air sinks.
The warm ground transfers energy to the air.
Warmer, less dense air rises and is replaced by cooler, sinking air
As the air cools, it becomes denser and starts to sink.
Sinking air moves to replace the rising air. When this air is warmed, it will rise and be replaced too.
