Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

This lab experiment shows students that mass is not gained or lost during a chemical reaction. Lab also includes a set of lab questions that requires students to balance the chemical equation for the reaction that occurs in this lab.

An interactive simulation that teaches about periodic motion, simple harmonic motion, and conservation of energy. Observe one or two pendulums to determine how the swing is influenced by the length of the string, the mass of the pendulum...

An interactive simulation that teaches about springs, Hooke's Law, and conservation of energy observing changes in kinetic, potential, and thermal energy by adjusting the stiffness and damping of springs holding various masses. This...

Manipulate the mass of a weight and the length of string in this interactive pendulum simulation. Change the speed, friction, and gravity to make the pendulum swing change as measurements are displayed on the screen. Younger students can...
