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...

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel 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...

Assist your class with understanding collisions as they apply the Law of Conservation of Momentum. Pupils measure the momentum before and after manipulation of two objects so that one strikes another in an inelastic collision. The lesson...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

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...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

How high will it bounce? Groups determine the height different balls bounce off of different surfaces. By performing the necessary calculations, they determine the initial and final momentum of the balls. The included worksheet provides...

Vive la résistance! Provide young historians with a list of important people and events during the French Revolution and Napoleonic periods.

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

If you have a rotating office chair in your classroom, you can have physics pupils participate in this simple, yet effective demonstration of angular momentum. One partner sits in the chair, arms outstretched, holding heavy weights. The...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

Dalton's Playhouse is an interactive concept simulation meant to convey fundamental concepts in chemistry, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.

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 with weights and scales that teaches about balancing chemical equations and conservation of mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional...

In this human behavior science fair project, the student will learn about Piaget's developmental stages and the Theory of Conservation. The student will investigate the age at which children understand the equality of numbers and mass....

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...

This site provides a set of four Physics problems dealing with the conservation of momentum principle.

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...

A collection of experiments, projects, and articles that will help students understand particle collision and mass, kinetic energy, magnetic field, the Large Hadron Collider, and detection of the Higgs particle.

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...
