This activity describes the basic structure of an atom using an edible model and explains the quantum mechanical nature of the atom. For example, originally, each electron orbital was pictured as having a specific...

The Physics Classroom presents this tutorial on the theory and fundamentals of vectors. Throughout the tutorial, students will learn how to “explain and analyze the motion of objects in two dimensions.” Some of the key...

The Physics Classroom presents this tutorial on momentum and its conservation. The three laws are three laws are explained and their application to the analysis of the motion of objects in one dimension is discussed....

In this interactive simulation, the path of a charged particle in a capacitor can be traced. Users may adjust the strength of field, initial velocity and mass of the moving particle, and magnitude of its charge. The...

New physics teaching resource sites continue to pop up every day, and this one from the University of Minnesota's Physics Education Research Group is a good find. The site is divided into two areas, one covering...

This activity was created by Jim and Jane Nelson, and is from the PTRA manual "Role of the Laboratory in Teaching Introductory Physics." It is a life-sized activity for students to investigate the forces and torques...

This website targets teachers, providing them with ideas for simple activities and experiments that can be used to demonstrate concepts related to kinetic and other forms of energy. Each activity and the science concepts...

This site, from UCLA's Department of Physics, contains web and in-class demonstrations of physics concepts in the topic areas of mechanics, harmonic motion and waves, electricity and magnetism, acoustics, optics, matter...

This webpage is simply an active calculator of buoyancy. It allows changes in mass, apparent mass, volume or density to explore variations. This site would be an excellent resource for any biology, chemistry or physics...
