Exciting Energy
compiled by Bernadette Pate Holt
Summary:
This unit is designed to introduce students to differing types of energy sources and their application in daily life.
Connection to the curriculum:
This module will integrate science, math, language arts, and technology.
Time:
This module will take about one week to complete.
Season:
This module may be taught during any season, however, it may be more effective in warmer months.
Materials:
See individual activities.
Objectives:
As a result of these activities, the student will:
* Be able to construct and explain simple circuits.
* Classify items as conductors and insulators.
* Explore the use of solar energy as an alternative to electricity.
* Assess the potential usefulness of chemical reactions as a source of
energy.
Background Information:
There are several key factors to our existence; air, water, food, and shelter. Of these, air is the only one that does not require some type of energy to produce for use in our daily lives. Water must go through a treatment system to be used in our home, food is produced through photosynthesis and the use of farm equipment, and shelter is created through the use of tools that require some form of energy.
There are two sources of energy:
1. Non-renewable sources
fossil fuels
nuclear energy
2. Renewable sources
solar
wind
hydroelectric
geothermal
wood and other biomass
The quality of these energy sources are as follows:
Very high: nuclear
High: natural gas, petroleum, coal
Moderate: wood
Low: wind, solar
While the United States accounts for only 6% of the worlds population, it consumes 30% of all non-renewable energy resources.
Evaluation:
Classification of power sources a Non-renewable and Renewable.
Completion of simple circuits and their diagrams.
Accurate descriptions of conductors and insulators.
Graphs of the roasting times of different colored marshmallows.
