Activity 1 in this module investigates Can my finger start a fire?

This two-part instructional activity teaches students about the process of generating electricity from coal and helps them research and discover alternate ways for using coal to produce electricity.

Explore and use models of electric fields to explain how charged objects interact with other objects.

In this module Activity 2 investigates What holds the atoms of a molecule together?The activity will explore what holds atoms together and why they from a molecule. Bonus reading includes Same Molecules but Different Representations.

Activity 4 investigates How does electron distribution impact our observations? Students have described how properties of molecules change depending on what atoms make up the molecule. In this activity students will use those ideas to...

Students will develop explanations connecting observations of water with properties that water exhibits through the following activities. Activity 1 How are water and other liquids similar? Activity 2 Why is water different from other...

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.

Activity 2 of the module explores: If you can't see it, how do you know it's there? Activities include the concepts of J.J. Thomson, electrons, and the Plum Pudding Model of the Atom.

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.
