Energy Transformations (Chapter 5 Lesson 2)

Energy Transformations (Chapter 5 Lesson 2)

Author: Jason Fritz
Description:

6.2.3.2.2 Trace the changes of energy forms, including thermal, electrical, chemical, mechanical or others as energy is used in devices.

Key Concepts for Students to Understand:

•What is the law of conservation of energy?
•How does friction affect energy transformations?
•How are different types of energy used and transformed?
 

•All forms of energy can be transformed into thermal energy.
•Energy can change form, but according to the law of conservation of energy, energy can never be created or destroyed.
•Friction transforms mechanical energy into thermal energy.
•Different forms of energy, such as sound and radiant energy, are used when someone talks on a cell phone.

Energy Transformations

The changes from one type of energy to another type of energy are called energy transformations.

Energy Pathway

http://www.sophia.org/energy-pathway


Harvesting energy from places such as wind turbines, radioactive elements, and fossil fuels require knowledge of concepts such as Transfer of Energy, Energy Forms and Electric Circuits. To establish a 
sustainable environment, comprehensive knowledge of Conservation of Energy is mandatory. Energy impacts everything and to understand it, is 
to create an environment in which to thrive. Skills and techniques mastered in Mechanical Energy and Fission and Fusion, will establish a foundational proficiency that is directly applied to understanding the creation and manipulation of Energy. Proceed completing the concepts in the "Energy Pathway."

The Transfer of Energy
In The Transfer of Energy, aspiring scientist Sylvie uncovers some compelling examples of how energy is never lost -- it just changes form as it moves through the universe. Discover that without energy transfers, there could be no life on Earth! Colorful, fast-paced visuals help students learn that heat energy from the sun is transferred to the Earth's surface and among objects in three different ways: conduction, convection and radiation. Find out that the sun's energy is also continually being transferred into different forms that we depend on to live and grow. A fun experiment with golf balls and ping-pong balls allows kids to see an energy transfer in action. James Watt's steam engine is an excellent historical example of how heat energy can be harnessed to do work as it changes form. Part of the multivolume Energy in Action Video Series.

Energy and Energy Transformations Choice Assignment

We have been studying the different forms of energy and how energy can transform from one form to the next. You job is to choose a method of demonstrating your knowledge of how energy is not created nor destroyed but transforms from one form to the next.

Plan
1. Look over all of your research from your notes and book analyzing the different form of energy and how they can transform from one form to the next.
2. Create a project that will demonstrate your knowledge of the forms of energy and their transformations.

Energy Observation and Transformation Stations Directions

Station 1 Materials:

1.  Sun/Window

2.  Calculator

Directions: hold the calculator near the window for a few moments. Take your finger and cover the solar panel of your calculator. Do you notice anything?

On your lab sheet use pictures and words to draw up the energy transformation happening at this station.

Station 2 Materials:

1.  Lamp

2.  Thermometer

3.  Sand

Directions: use thermometer to take temperature of sand. Plug in lamp and have shine on sand for 1 minute. Take temperature again. Did you notice any change?
