Structure and Properties of Matter (9
- 12)
* Atoms interact with one another by transferring
or sharing electrons. * An element is composed of a single type of atom. * Bonds
between atoms are created when electrons are
transferred or shared. * The physical properties of
compounds reflect the nature of the interactions among its molecules.
* Solids, liquids, and gases differ in distances
between molecules & atoms and the energy that binds them together.
* Carbon atoms can bond to one another in chains and rings to form a variety of structures, including the
large molecules of life. (NSES,
1996)

This incredible learning tool is called
States of Matter and comes to us from the incomparable web site
called PhET.
Watch different types of molecules form a solid, liquid, or gas. Add or
remove heat and watch the phase change. Change the temperature or volume
of a container and see a pressure-temperature diagram respond in real
time. Relate the interaction potential to the forces between molecules.
A great learning tool! Thanks to all at
PhET. |

This "learning tool" is called
WebElements. There are lots of
periodic charts out on the web, but this one is one of the best.
ScientificAmerican.com has
selected the WebElements web
site as a winner of the 2002 Sci/Tech Web Awards. |

The name of this learning tool is called
Gas Properties. This is a Java applet, just click RUN NOW to start.
Pump gas molecules to a box and see what happens as you change the
volume, add or remove heat, change gravity, and more. Measure the
temperature and pressure, and discover how the properties of the gas
vary in relation to each other. This tool is brought to us by The
PhET
Project and made possible by the
Kavli Operating Institute. |

The
Chemistry Collective is a
collection of virtual labs, scenario-based learning activities, and
concepts tests which can be incorporated into a variety of teaching
approaches as pre-labs, alternatives to textbook homework, and in-class
activities for individuals or teams. It is organized by a group of faculty
and staff at Carnegie Mellon University for college and high school
teachers. |

This elegant and conceptually clear
"learning tool" is called
Gas Law
Animation. Within a closed container students can adjust pressure,
volume, and temperature. They can also increase and decrease the number of
Helium and Neon atoms that enter the container. Make sure you click on the
"click here" button for a great pdf that describes the instructions and
more! Developed by Dr. John Gelder at the
Department of Chemistry at
Oklahoma State University. |

This learning tool is called
Density and
has been produced by the incredible people at the
PhET web site. Discover the
relationship between mass, volume and density by weighing and submerging
various materials under water. Do objects like aluminum, Styrofoam, and
wood float or sink? Can you identify all the mystery objects by weighing
them and submerging them underwater to measure their volumes?

Just click the element you want to start
with and then click one that will bond with it, the name of this "learning
tool" is called
Bonding. This textured and elegant demonstration is brought to us by
the
Department of Chemistry at Iowa
State University. |

With this "learning tool" students can
learn to use the
Element Builder. One of the most innovative science education
companies is
Explorelearning.com, they call their simulations, Gizmos. They are a
subscription site ,
but they allow you to see this Gizmo for 5 minutes.
Shockwave is required. |

With this "learning tool" you can see
how the volume of a container of gas is affected by changes in number of
gas particles, velocity, and atmospheric pressure. The name is
Molecular
Model for an Ideal Gas and comes to us from H Wang. This is a java
applet. |

This simple and elegant learning tool is
called
Boyle's Law. Just press your space bar and drag the plunger to see
the relationship between volume and pressure. The interactive creates a
data table automatically and students can choose to test air, hydrogen,
helium, or oxygen. This fun interactive was created by
Thomas Greenbowe
at Iowa State University. |
