Weight and Mass & Forces in Equilibrium
I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Chemical Equilibrium
We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...
Concord Consortium
Pendulum and Spring
Up, down, back, and forth. When you make a pendulum out of a spring, there's a lot to observe. Aspiring masters of motion examine the combined kinetic energies of spring and pendulum motion using a detailed interactive. Learners observe...
Concord Consortium
Spring and Mass
Here's a resource with more bounce for the ounce! Engage your physical science class with an interesting interactive that allows individuals to perform tests with a mass attached to a spring. Participants can customize the scenario by...

Solubility Product of an Ionic Compound
How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...
Khan Academy
Khan Academy: Weak Acid Base Equilibria
Learn about weak acid and base ionization reactions and the related equilibrium constants, Ka and Kb. Relate Ka and Kb to pH, and calculate percent dissociation.

Ck 12: Le Chatelier's Principle
[Free Registration/Login may be required to access all resource tools.] Students explain the factors that stress a system at equilibrium and use Le Chatelier's principle to predict how the system will respond to each stress. They will...
Physics Aviary
Physics Aviary: Practice Problems: Gas Partition Problem Level 2
Determine the temperature required to keep a piston in equilibrium. You must use information about the speed of the atoms in the left hand chamber to help you find the equilibrium pressure.

Ck 12: Chemistry Simulation: Flat vs. Fizzy Soda
[Free Registration/Login Required] Explore Le Chatelier's Principle by changing the volume, pressure, and temperature in a bottle of soda. Try carbonating the soda to see how adding a reactant affects the chemical equilibrium.
