and properties of matter.
Tools - Use content-specific tools, software and simulations
(e.g., environmental probes, graphing calculators, exploratory environments,
Web tools) to support learning and research.
and Decision-Making Tools - Routinely and efficiently use on-line
information resources to meet needs for collaboration, research,
publications, communications, and productivity.
- You will study
the effects of a change in temperature on gas molecules using a balloon
and an Erlenmeyer Flask.
- After observing
changes in the balloon during the procedure, you or you and your group
will, with the aid of the Beginner's
Guide to Rockets, offer an explanation of the changes and apply
what you have learned to a rocket nozzle.
- You will investigate
a question you or you and your group have about temperature and/or
