Balancing Chemical Equations
x
VITAL INFORMATION
line
Subject(s):
Mathematics, Science, Technology

Grade/Level:
8

Time Required:
2 class periods. 45 Min. per class.

Objective(s):
Students will be able to analyze, set up, and balance chemical equations.

Summary:
Students will be introduced to three-dimensional models of various elements through VRML. The students will inquire how to build three-dimensional models of molecules. As the students are balancing one-step algebraic equations they will be introduced to balancing chemical equations.

IMPLEMENTATION

1. Introduction of Balancing Chemical Equations*
 
 
2. Building Molecules*
 


Resources and Unit Handouts:
  • Materials and resources:
    Technology resources:
    PowerPoint, TextPad
    Internet Explorer
    Entension Activity Worksheet


STANDARDS
Standards compiled from learning activities:
International- Intl. Technology Education Association: Standards for Technology Literacy
• Category The Nature of Technology
• Standard 1Students will develop an understanding of the characteristics and scope of technology.
• Grade Range 6-8
 Benchmark HTechnology is closely linked to creativity, which has resulted in innovation.
Most inventions are inspired by perceived needs and wants- the hairbrush, for example. Other inventions are linked to developing creative ideas and the way a person uses them, not necessarily their intended use. For example, the invention of the tea bag grew out of a packaging strategy to replace expensibe tin containers. Althought teas was packaged in small silk bags to give away as sampless, some useers thought it was a new ways to brew the tea, and thus the tea bag was born. An invention can always be improved, and trying new ideas is often key to that improvement.
