Concord Consortium What Are All Materials Made Of?

Activity 3 of this module explores: Is the particle model always better? Models are considered most useful when a variety of observations can be explained. A model of matter should explain observations of all types of matter. In this...

Activity 2 of this module explores: Does 5 + 5 always equal 10? In this activity liquids are mixed together and evaluated whether the continuous or particle model of matter provides a better explanation of observations of the behavior of...

Activity 4 of this module determines: Which model best supports our observations? This activity reviews the evidence gathered in this investigation and considers how that evidence informs your model of matter. A timeline of the history...

In this learning module from The Concord Consortium, students will watch what happens when a Van de Graaff generator is used.

In this learning module from The Concord Consortium, students will start to develop their own computer simulation models of how attraction and repulsion between charged objects work.

In this learning module from The Concord Consortium, students will investigate how polar and nonpolar regions in big molecules interact to result in certain shapes and properties for those molecules.

The module will develop, revise, and interpret representations of atomic structure and interactions of charges within atoms. The following activities will be explored: Activity 1. What are the particles that make up all substances and...

Activity 1 of this module explores What are the particles that make up all substances, and how small are they? A history of the atom is included.

Activity 4 What are the electrons? This question is answered in the context of Niels Bohr's model and the probability model of atomic structure.

In this learning module from The Concord Consortium, students will will explore how uncharged objects interact with charged objects.
