Opening Objectives  WHAT IS ENERGY?  How is it transferred ?  What are the types of energy?

Think-Pair-Share  Grab your pair buddy and talk about what you think energy is and why it is important.

Key terms  Energy  Potential energy  Kinetic energy  Transfer  Work  Heat  temperature

What are Energy and work?  Energy is defined as the ability to do work.  Work is defined as the transfer of energy.

Video Slide  Here is a video showing the many ways that energy is used on a regular basis and even some not so regular.

Types of energy  There are two main types of energy that we will focus on in this unit.  Potential energy And  Kinetic energy

Types of energy (cont.)  Potential energy is energy stored due to an object’s position.  Ex. A rock sitting at the edge of a cliff has potential energy. If the rock falls, the potential energy will be converted to kinetic energy.  Kinetic energy is energy of a moving object.  Ex. A car driving up a hill is kinetic energy but when it stops at the top it becomes potential energy.

Fun facts about energy  Energy is never created or destroyed; it merely changes forms.  Most types of energy are either a form of kinetic energy or potential energy.  Plants use energy from sunlight during an important process called photosynthesis.  A person standing on a diving board above a swimming pool has gravitational potential energy.

Critical connection  When you get home today make a list of all the things you do.  Next determine whether or not it requires potential or kinetic energy.  When we return we will compare our list to see which we use more.

Closing objectives  What energy is. The ability to do work. What work is. The transfer of energy. Types of energy. Potential- stored energy Kinetic –energy In motion
