能量守恒定律指出：能量不能被________或__________

Energy 能量

• The ability to do work and cause change. Energy transfers cannot be seen with the human eye. 

  做功和引起变化的能力。能量转移是肉眼无法看见的。

• There are many forms of energy:

• 能量有多种形式：

What is an electron?

什么是电子？

Electrical Energy. 电能

• Electrical energy is caused by moving electric charges called electrons. The faster the charges move, the more electrical energy they carry.

• 电能是由移动的电荷（称为电子）产生的。电荷移动得越快，它们携带的电能就越多。

• As the charges that cause the energy are moving, electrical energy is a form of kinetic energy.

• 由于产生能量的电荷在移动，所以电能是一种动能。

• Lightning, batteries and even electric eels are examples of electrical energy in action!

• 闪电、电池甚至电鳗都是电能发挥作用的例子！

Light Energy. 光能

• The Electromagnetic Spectrum includes all kinds of light. The human eye can only see visible light.

• 电磁波谱包括各种光。人眼只能看到可见光。

• When you watch TV, send a text message, or pop popcorn in a microwave, you are using electromagnetic energy. You depend on this energy everyday. Without it, the world you know could not exist.

• 当你看电视、发短信或用微波炉爆米花时，你都在使用电磁能。你每天都依赖这种能量。没有它，你所知道的世界就不可能存在。

What does 'Therm' mean in Greek?

希腊语中的“Therm”是什么意思？

Thermal Energy 热能

• As a form of energy cannot be created or destroyed. It can be transferred from one place to another. Heat can also be converted to and from other forms of energy.

• 能量是一种既不能被创造也不能被毁灭的能量形式。它可以从一个地方转移到另一个地方。热量也可以与其他形式的能量相互转化。

• Thermal energy is the energy a substance has due to its temperature. (The energy of moving or vibrating molecules。)

• 热能是物质因温度而具有的能量。（运动或振动分子的能量.）

What do you see/hear? 你看到/听到了什么？

What do you think? 你觉得怎么样？

What do you wonder? 你想知道什么？

Sound Energy. 声能

• Light and sound energy both travel in the form of waves.

• 光能和声能都以波的形式传播。

• Sound is the energy things produce when they vibrate (move back and forth quickly).

• 声音是物体振动（快速来回移动）时产生的能量。

Chemical Energy. 化学能

• Breaking chemical bonds requires energy. 打破化学键需要能量

• Forming new chemical bonds releases energy. 形成新的化学键会释放能量

• When bonds between atoms are broken or formed, this is called a chemical reaction.

• 当原子之间的键断裂或形成时，这被称为化学反应。

• Is the potential energy stored in the arrangement of atoms within molecules.

• 是分子内原子排列中储存的潜在能量。

What is a neutron?

什么是中子？

Multiple Choice

Which particle makes the identity of the atom?

哪种粒子构成了原子的特性？

• Proton

  质子

Nuclear Energy 核能

• Nuclear energy can be used to create electricity, but it must first be released from the atom. In the process of nuclear fission, atoms are split to release that energy.

• 核能可用来发电，但必须先从原子中释放出来。在核裂变过程中，原子分裂并释放出能量。

• Nuclear energy is the energy in the nucleus, or core, of an atom.

• 核能是原子核或核心中的能量。
