This lesson plan explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. Students think about how atoms and molecules can influence new technologies...

This lesson focuses on the structure of atoms. All substances are made from atoms. Each atom is made of a nucleus - containing protons and neutrons - surrounded by electrons. It provides a link to an assessment.

Describes the structure of an atom and the characteristics of the electrons, neutrons, and protons inside it. Includes some interesting facts about atoms.

An atom is made of three parts - protons, neutrons, and electrons. Here you can explore these different parts.

Fun and interesting illustrated information on atoms including composition, elements, and history.

We're about to move into the modern age of physics. In the early 1800's, scientists began examining the basis of matter, space, and time. Sometimes it gets very confusing, but the big idea is that Newton's physics describe about 90% of...

Students explore the periodic table and learn the basic information given for elements: the name, symbol, atomic number, and atomic mass for each element.
